Evaluation of food safety training on hygienic conditions in food establishments

Food handlers' training is fundamental in order to ensure the safety of the foodstuff. However, the success of training programs that provide only information is unclear and changes in improper food practices are not usually achieved. Food training programs based on theoretical as well as practical activities have been revealed as an important tool in which food handlers can put information into practice. Thus, the objective of this study was to assess the influence of food safety training, based on both theoretical and practical approaches, on the microbiological counts of food contact surfaces, food tools, food equipment surfaces and hand washing in canteens and cafes of one university campus. After food safety training, total plate counts decreased about 60% in the case of canteens and almost 45% in cafes while moulds and yeasts decreased approximately 65% in canteens and 55% in cafes. In terms of location, the microbiological reductions observed were higher for food equipment in canteens and for food tools in cafes. The microbiological counts of food handlers' hands decreased after both food safety training and disinfection. Food safety training influenced the reduction of overall microbiological parameters. Parametric t-tests (after vs before training) indicated that reductions were statistically significant before and after disinfection for total plate counts. The decrease observed for total coliforms and Enterobacteriaceae, were statistically significant only before disinfection. The food safety programs cannot be based entirely on a theoretical approach but also on adequate training which includes a practical approach. The success of the microbiological reductions in the study was associated to the practical lessons which let the handler put into practice the knowledge acquired in the theoretical part.     

Occurrence of mycotoxins in commercial infant formulas locally produced in Ouagadougou (Burkina Faso)

Cereals products enriched with leguminous or oleaginous are used in Burkina Faso as food complement or to avoid infant malnutrition. Infant formulas from cereals are consumed as food supplements after the weaning age. They are produced in Burkina Faso with a mixture of several cereals (maize, millet, rice, or sorghum), leguminous (bean), oleaginous (peanut, soya or sesame), sugar or salt and sometimes milk powder. The production is artisanal or semi-industrial. These infant foods from cereals should be free from mycotoxins and pathogenic bacteria. The objective of this work was to determine the occurrence of mycotoxins like aflatoxins, ochratoxin A and fumonisins in infant formulas and grains in Ouagadougou (Burkina Faso). The mycotoxins (aflatoxins, ochratoxin A and fumonisins) were determined by HPLC-FLD in 248 samples of infant formulas produced by the Recovery and Nutrition Education Centers (CRENs) and sold on the market places in Burkina Faso.Results showed that the majority of samples of infant formulas presented high levels of mycotoxins. The frequency of contaminated samples by aflatoxin B1, ochratoxin A and fumonisins in analyzed samples were 83.9% (167/199), 7.5% (15/199) and 1.5% (3/199), respectively. The highest values registered in infant formulas were 900, 6 and 3 times higher for aflatoxin B1 (EU limit: 0.1 μg/kg), ochratoxin A (EU limit: 0.5 μg/kg) and fumonisins (EU limit: 200 μg/kg), respectively, than the EU regulation limits (1881/2006). This study presents the first results concerning the safety assessment of infant formulas regarding mycotoxins in Burkina Faso.     

Hygiene knowledge and practices of night market food vendors in Tainan City, Taiwan

Night markets are a unique part of Taiwanese culture and are ideal places to visit to taste local delicacies. “Visiting night markets” not only has become a habit for local residents, but also a particular favorite for non-local tourists. Street food vending in the night markets has been increasing for several years but this growth presents public health challenges, with evidence of diarrheal diseases. Therefore, there are emerging needs for understanding the hygiene knowledge and practices of food vendors to ensure hygienic preparation of street foods. This empirical study can be used in understanding the current situation of food hygiene practices in tourist night markets and in exploring proper strategies for improving food safety at the markets.     

Evaluation of basic knowledge on food safety and food handling practices amongst migrant food handlers in Peninsular Malaysia

This study was aimed to measure the basic knowledge on food safety and food handling practices among migrant food handlers as these information is scarce in Malaysia. A cross-sectional study was conducted face-to-face amongst 383 migrant food handlers from three major cities in Peninsular Malaysia through questionnaire. Socio-demographic information of all respondents was collected. Questions on food safety knowledge (i.e. food cleanliness and hygiene, symptom of foodborne illnesses and foodborne pathogens) and food handling practices were assessed. The compiled data were analyzed by using the Statistical Packages for Social Science (SPSS) 16.0. Overall, migrant food handlers had poor level of knowledge on food safety with an average food handling practice. Significant effects were observed between respondents’ food safety knowledge and socio-demography (country of origin and educational level) and two factors namely; respondents’ nationality and attendance at food training programs showed significant associations with their food handling practices. Multiple logistic regression analyses revealed that attendance at food training programs was a significant and independent predictor of the respondent’s food handling practice. The study’s findings highlighted issues with regards to the extent of knowledge acquisition on food safety and hygiene by migrant food handlers. Therefore, this warrants improvements not only in the better delivery methods of training modules but also tight enforcement of attendance at the programs by the respective authorities.     

Food safety knowledge,attitudes and practices of street food vendors and consumers in Port-au-Prince,Haiti

This study had the major objective of determining the food safety knowledge, attitudes and practices of vendors and consumers of street food in Port-au-Prince, Haiti. Haiti currently has no food safety legislation in place. 160 consumers and 80 vendors from four different communes (Tabarre, Delmas, Pétion-ville and downtown Port-au-Prince) volunteered to participate in the study. In general, consumers and vendors exhibited average food safety knowledge and attitude levels. Gender, training, level of education and location did not have a significant effect (p < 0.05) on the level of food safety knowledge of the consumers. Vendors were determined to have higher levels of food safety knowledge than consumers, whilst trained vendors had better food safety knowledge and attitudes compared to untrained vendors. The majority of vendors and consumers were aware of the importance of washing hands and proper cleaning with regards to the prevention of foodborne diseases. However, some other aspects were of concern. Consumers and vendors did not know that Hepatitis A, Salmonella spp. and Staphylococcus spp. are pathogens responsible of foodborne diseases. They also had difficulties in identifying the groups at risk of foodborne diseases and most were unaware of the importance of reheating food to fight against foodborne diseases. In the observational part of the study, it was found that in 60% of the cases, flies and animals were evident around the stall and 65% did not have access to potable water. The majority served food with bare hands and did not wash their hands after handling money. Additionally, 70% of the vendors did not chill pre-cooked food. The conditions in which street food vendors operate in Port-au-Prince are largely unacceptable from a food safety point of view and an effort should be made to provide them with adequate infrastructure including potable water, toilets and waste disposal facilities. The results of this study should be used to generate part of the impetus towards the development of enforcement of appropriate food safety legislation in Haiti.     

Evaluating levels of knowledge on food safety among food handlers from restaurants and various catering businesses in Vienna,Austria 2011/2012

The aim of this study was to detect the most important gaps in knowledge on food safety among food handlers in Vienna, Austria and to identify possible differences in levels of knowledge between food handlers from restaurants and catering companies. The survey was conducted from May 2011 to January 2012 in Vienna and 234 food handlers participated. The average knowledge score for all food handlers was 76%. We revealed no significant difference between the two sample groups; food handlers from catering businesses scored similar (75%) to those from restaurants (76%). Persons with a training at their current workplace (internal and external) scored significantly higher (82%) then persons without an on the job training (71%). Food handlers passing the mandatorily required yearly food safety training had a higher knowledge than persons without this on-the-job training (p ≤ 0.001); 23% of the food handlers didn't participate in any training during the last year. The study identified substantial knowledge gaps concerning correct temperatures for cooking, holding and storing foods. Data from this project underline the value of harmonized action in the field of food safety, but also indicate considerable potential for further improvement in Austria.     

Knowledge, attitudes and practices of workers on food hygienic practices in meat processing plants in Fars, Iran

This cross-sectional study was conducted to evaluate the knowledge, attitudes and practices of food workers in four meat processing plants in the Fars province, southern Iran. A self-administered, structured questionnaire was designed and completed by 97 food workers during November 2006–January 2007. Results indicated that the respondents had acceptable level of knowledge, excellent attitudes and poor practices toward food hygiene measures. Almost all of the food workers (97.9%) were aware of the critical role of general sanitary measures in the work place while there was lack of knowledge about microbial food hazards in the majority (67–78%) of them. A significant negative correlation was observed between knowledge and practices (r_s = −0.20, P = 0.04), and attitudes and practices (r_s = −0.27, P = 0.009), revealing that increased knowledge and even attitudes toward food safety does not always result in positive change in food handling behaviors.     

Food safety knowledge,attitudes and practices of street food vendors and consumers in Ho Chi Minh city,Vietnam

This study had the major objective of evaluating the food safety knowledge, attitudes and practices of consumers and vendors of street foods in Ho Chi Minh City (MCMC), Vietnam. There were three main surveys performed in this study. A total of 120 consumers and 40 street food vendors from four districts [Binh Thanh (BT), Thu Duc (TD), district 3 (D3) and district 8 (D8)] in HCMC contributed to the study on a voluntary basis. The surveyed consumers had adequate levels of food safety knowledge and attitudes. No significant difference (p > 0.05) occurred between the food safety knowledge levels of the consumers on the basis of gender. However, significant differences (p < 0.05) occurred on the basis of age, education level, food safety training status and location. In contrast, the street vendors had poor food safety knowledge and attitude levels. No significant differences (p > 0.05) were observed in the food safety knowledge levels of the vendors on the basis of gender and age. However, significant differences (p < 0.05) were found on the basis of food safety training status and education level. It was also noted that the vast majority (95%) of the vendors had not received any food safety training. With regards to the practices, it was determined that 52.5% of the vending sites were open air stands without any protection from the sun, wind and dust. 52.5% the vending stalls had no direct access to potable water, while 47.5% did not have adequate hand washing facilities and a further 30% lacked proper waste water and food disposal facilities. In addition, 52.5% of the vendors did not separate raw, partially cooked food and cooked food products. These findings highlighted that street food vendors in HCMC generally have poor food handling practices and most are operating under unhygienic conditions. These results should provide the Vietnamese government with even more reasons to increase their current efforts to improve the safety of street foods and food safety awareness of the consumers.     

Food safety knowledge,attitudes and self-reported practices of food handlers in institutional foodservice in Accra,Ghana

The aim of this study was to evaluate the food safety knowledge, attitude and practices (KAP) of food handlers from institutional food service establishments that serve hospitals, boarding senior high schools and prisons in Accra, Ghana. A total of 278 food handlers (56.8% of hospital, 30.9% of schools and 12.3% of prison food service) participated in the cross-sectional study. Data was collected by face-to-face interviews, and responses were scored to determine the level of food safety KAP. Respondents who scored ≥70% of the maximum possible score were adjudged to have sufficient knowledge and practices and positive attitudes. Results showed that respondents generally had insufficient food safety knowledge and practices with means scores of 20.99 ± 7.64 (46%) and 9.35 ± 5.62 (52%) respectively. Attitudes towards food safety were generally negative but with a comparatively higher mean score of 12.64 ± 3.06 (63%). Areas of most concern were 1) Lack of knowledge of sources of contamination/cross-contamination and appropriate holding temperatures for food. 2) Poor practices included multiple freeze-thaw cycles for frozen food and 3) Infrequent hand washing during food preparation after coughing or sneezing. There is the need for continuous risk based training to educate and effect behavioral changes among food handlers. This process will encourage positive attitudes towards food safety and consequently promote good food safety practices.     

Food safety knowledge of foodservice workers at a university campus by education level,experience, and food safety training

Food safety knowledge of university foodservice workers was evaluated and the relationship between food safety knowledge and education level, length of employment, and food safety training was assessed using a 40-item food safety questionnaire. Each knowledge question was scored as “1” for a correct answer and as “0” for an incorrect answer. The relationships between the level of education and food safety knowledge scores and length of employment in the foodservice industry and food safety knowledge scores were determined using bivariate correlation analysis. A total of 63.5% of the respondents had limited knowledge, 79% were well-informed about hygiene practices, while 33.9% of persons knew of correct time-temperature control measures. Kendall's tau = 0.067; p = 0.294 revealed a lack of strength of the relationship between education level and food safety knowledge. The relationship between length of employment and food safety knowledge was Kendall's tau = −0.133; p = 0.121. No mean differences (p = 0.426) were observed for mean knowledge scores between groups of food safety trained and untrained persons. Neither education level, nor the length of employment in the foodservice industry had a significant impact on food safety knowledge. The authors recommend that in order to improve food safety knowledge, attention should be given to the planning, implementation, monitoring, and evaluating food safety education programs.     

Essential tools for food safety surveillance in catering services: On-site inspections and control of high risk cross-contamination surfaces

The aim of this study was to assess the routine food safety procedures carried out in catering services so as to provide a useful monitoring program for managers based on the relevant deviations detected in the observational survey and activities carried out in 15 catering services located in Navarra (region of northern Spain). The main hygiene standards, food handler practices and compliance with the HACCP system were evaluated by means of visual inspections (checklist), monitoring of critical control points (food storage and food processing temperatures, total polar compounds) and microbiological analysis of food-contact and hand-contact surfaces. While general high scores were obtained in the observational survey (73.3% above 36 points), none of the evaluated services had obtained the maximum rate of 48 points. The mayor deficiencies were related to the presence of dirty uniforms, improper hand washing or use of gloves, incorrect disinfection of vegetables and the missing records of stated critical points (temperatures and polar compounds in oil). The performed monitoring activities confirmed the safety of frying oil in all the kitchens, despite the fact that only 33% of them applied scientific methods to measure polar compounds. By contrast, holding temperatures were unsatisfactory in 77% of cold dishes and in 19% of hot meals. Despite the fact that 77% of food contact surfaces were considered acceptable (<4 CFU/cm²), high levels of total mesophilic microorganisms and Enterobacteriaceae were detected in hand-contact surfaces such as aprons and handles. The periodic visual supervision focusing on hygienic practices and the microbiological surveillance of surfaces of high risk for cross-contamination should provide valuable information for improving the knowledge, attitudes and practices of food handlers regarding food safety.     

Knowledge,attitude and practices of food safety amongst food handlers in the coastal resort of Guangdong,China

In order to identify risk factors contributing to foodborne disease outbreaks in Guangdong province, China, the present study evaluated the knowledge, attitude, and practices (KAP) of food safety among food handlers in a coastal resort area that has a high incidence of foodborne disease outbreaks from Vibrio parahaemolyticus. The KAP of 171 food handlers from 22 food establishments—including seven food establishments in which outbreaks had occurred and 15 in which outbreaks had not occurred—were evaluated.A self-administered questionnaire designed to access the KAP of food safety was completed by the food handlers. The majority of respondents didn't know the maximum stored time at room temperature and the most common agent of foodborne disease in seafood. Most of the respondents' attitudes about food safety and training were positive. When asked about the practices undertaken, about one-fifth of the respondents admitted they had mixed food (raw and cooked) containers in varying degrees. There was significant variance among different food establishments, different ages, and different times of training. Training programs may achieve good results, but training should be more selective, educate the trainees to realize food safety is more important than fresh seafood, target how to cook seafood and lower the risk of microbiology in food, and conduct particularly focused training among managers and newcomers.     

Street vendors in Patna,India: Understanding the socio-economic profile,livelihood and hygiene practices

Street food vending is fundamental to daily life in many low and middle income countries where much of the urban population rely on food provided by street vendors. While street vendors are known to be important providers of food; limited research has investigated vendor’s hygiene practices and their socioeconomic circumstances in India. The aims of this study were to investigate the hygienic practices of food vendors and the context of their socioeconomic and living circumstances. Structured interviews were conducted with 31 street food vendors in Patna, India. The interviews explored issues around vending, hygiene practices, planning, and financial stability. Findings from this study indicate that food vendors are aware of good basic hygiene practices despite having low levels of literacy, low incomes, and limited job security.     

Knowledge,attitudes and practices of food handlers on food safety in food service operations at the Universiti Kebangsaan Malaysia

This study was conducted to determine the level of knowledge, attitudes and practices of food handlers in food service operation at the main campus of Universiti Kebangsaan Malaysia (UKM) regarding food safety. Data were collected from 112 food handlers through questionnaires which consisted of questions about knowledge, attitudes and practices. The results showed that there was significantly positive correlation among the three levels and respondents possess good scores for knowledge (19.68 ± 3.87) about personal hygiene, foodborne diseases and temperature control of food; for attitudes (89.26 ± 8.66) on safe food handling, and for practices (90.02 ± 8.23), specifically for appropriate hand washing, use of gloves in food preparation and prevention of food hazards. About 73.2% of respondents never attend any training related to food safety and majority show poor knowledge of pathogens associated with disease-causing agents as well as critical temperatures for storage of ready-to-eat foods. Therefore, effective and ongoing training on food safety and hygiene must be given to all food service employees to ensure the safety of food provided.     

Knowledge of food safety and food handling practices amongst food handlers in the Republic of Ireland

Food safety concerns have existed for a long time, as millions of people across the globe suffer from food borne disease every year. Contamination of food owing to limited knowledge of food safety practices primarily increases the risk of food borne illnesses. In the present study, quantitative research was carried out to gauge the level of food safety knowledge amongst people living in Ireland. A total of 1069 participants from all over the Republic of Ireland contributed to the survey (of which 821 were included in this research). Results showed that the residents of Ireland overall had an average level on knowledge of food safety practices (67.0% passing rate). They had an average level of knowledge in food storage (52.8% passing rate), usage and maintenance of the kitchen facilities (59.0% passing rate), and personal hygiene (61.0% passing rate). Conversely, they had a critically low level of knowledge in food handling (10.8% passing rate) and food poisoning (20.1% passing rate). The results of the present study also showed that, the level of knowledge of food safety practices varies amongst the residents based upon their gender, age, place of residence, education level, and marital status, while no significant difference in the knowledge level was observed based upon their per capita income. The study thus, highlights that there is scope for improvement for the residents to advance their knowledge of food safety practices. Therefore, it can be recommended that researchers, educators, food safety communicators, and the media can engage in educating the population, to help the residents advance their food safety knowledge to safer food practices.     

Protecting child health by preventing school-related foodborne illnesses: Microbiological risk assessment of hygiene practices,drinking water and ready-to-eat foods in Italian kindergartens and schools

The purpose of this study was to evaluate hygiene and microbial safety in 26 Italian school catering establishments. This involved monitoring the microbiological quality and safety of ready-to-eat foods (n = 395), drinking water (n = 43), food contact surfaces (n = 139), and food handlers (n = 249). Food samples analyses revealed an adequate level of microbiological quality and safety. Of particular concern was the isolation of Salmonella spp. and Listeria monocytogenes in 5.8% and 1.9% of raw vegetable samples, respectively. Escherichia coli counts exceeded the microbial reference standards in 8.6% of soft cheeses samples and in 27.3% of multi-ingredients preparations. Staphylococcus aureus counts exceeded the reference limits only in 5.7% of soft cheeses samples. The hygienic level of food contact surfaces was very high, since only 1.4% of samples showed unacceptable contamination. Concerning the food workers' hands, the results showed that the total bacterial count, coagulase positive staphylococci and Enterobacteriaceae levels exceeded the reference standards in 18.1%, 10.4%, and 11.2% of cases, respectively. The results of the water analyses indicated that 47.8% of the tap water and 10.0% of drinking water samples examined were found to be non-conforming to law limits. In conclusion, since children have a relatively lower immunity than adults, additional safety measures are needed to protect them from foodborne pathogens and high microbial contamination in school lunches. Consequently, our results suggest that various changes in the timing of food preparation and holding temperatures are needed, and good manufacturing practices and HACCP principles need to be applied more rigorously.     

Study on food safety concerns,knowledge and practices among university students in Saudi Arabia

Food Safety is important not only for the health of consumers but also the entire food industry and regulatory authorities. University students are an important target group as they are most likely to engage in risky eating behaviors and food handling practices making them susceptible to foodborne illness. The objectives of this study were to assess the level of food safety concerns, knowledge and practices among male and female university students of King Saud University, Saudi Arabia. Information concerning sociodemographic and academic characteristics and food safety knowledge were collected using self-administered questionnaire. Food safety questions were divided into four sections that covered key food safety concepts. A total of 808 students took questionnaires of which 66.08% responded (mean age 21.1 ± 2.9). Major food concerns for students were food taste, food temperature, food presentation, wellness of cooked food, cleanliness of serving area and appearance of food handlers. Students displayed good knowledge concerning food safety. Respondents were most knowledgeable about the cleanliness of kitchen surfaces and utensils, prevention of cross contamination and hand hygiene but demonstrated poor knowledge about heat treatment of food and temperature. Good knowledge of food safety was reflected in food safety practiced by the students except temperature control. Chi-square test results revealed that both male and female students demonstrated comparable food safety knowledge and practices. This is probably the first gender-based report on the food safety concerns, knowledge and practice among students of King Saud University, Saudi Arabia. The study highlights the need for educational programs that aim not only to provide knowledge but also encourage the students to practice the food safety measures strictly.     

Hygiene and good practices in school meal services: Organic matter on surfaces,microorganisms and health risks

The aim of this study was to evaluate and classify the sanitation and hygiene conditions in Porto Alegre/Rio Grande do Sul (RS) public schools using an analysis of surfaces that come in contact with food and a food safety checklist validated for the school environment. The following mesophilic heterotrophic bacteria count medians were observed on each piece of equipment or utensil studied: countertops, 27.3 Colony-Forming Units (CFU)/cm²; cutting boards, 15 CFU/cm²; blenders, 14.5 CFU/cm²; dishes, 2 CFU/cm²; and refrigerators, 1 CFU/cm². The median of the surface measurements analyzed by adenosine triphosphate (ATP) bioluminescence was less than 40 Relative Light Units (RLU)/100 cm² for all equipment and utensils, except for the countertop surface, which had a median of 52.5 RLU/100 cm². The data from 120 schools showed that 33, 64 and 3% were classified as high, regular and low health risk, respectively. The results showed that most schools were exposed to cross-contamination with failures especially with regard to environmental hygiene and procedures. Failures related to both factors potentially raise the risk of outbreaks in this environment. The scores used enabled the classification of school meal services and the identification of the points that need more attention. Intervention strategies that target different aspects of food handling, not only knowledge, may be promising in this scenario, which may address problems that mainly involve the food handler and promote changes in food handling practices.     

Urban street foods in Shijiazhuang city,China: Current status,safety practices and risk mitigating strategies

Street foods often reflect traditional local cultures and offer a unique cultural experience to tourists and even to ordinary consumers. With the increasing pace of globalization and tourism, the safety of street foods has become one of the major concerns of public health. There is an urgent need, in China, to establish a national program to raise the food safety awareness and knowledge of street food vendors. The safety and hygiene status of street foods in Shijiazhuang city was investigated. Data on the street food vendors' food safety knowledge and practices, inspectors' regulatory capacity and consumers' purchasing habits were collected. Potential hazards in the preparation and sale of street foods were analyzed and strategies for ensuring the safety of street foods were recommended. The study showed that the street food safety risks are primarily due to the use of unqualified raw materials encouraged by ineffective inspections, poor infrastructure at the street food vending sites and lack of sanitation knowledge among street food vendors. In order to prevent street foods from being contaminated, more stringent and effective routine supervision and food safety practices should be adopted and the environmental conditions and facilities should be improved. Regular training in food processing technology, food safety knowledge and practical food safety evaluation methods should also be strengthened among street food vendors and food safety inspectors.     

Stakeholders' perceptions,attitudes and practices towards risk prevention in the food chain

An online survey was conducted to describe stakeholders' perceptions, attitudes and practices towards risk prevention in the food chain and to explore if common features could be extracted from different fields of competency or groups of stakeholders. Out of 80 participants, 60% believed that pathogenic microorganisms were the main hazard to prevent. Twenty-four percent perceived climate change as the main risk factor. Seventy-three percent believed that hazards in the food chain are preventable and they often showed a positive attitude towards risk prevention measures. The opinion of 75% of stakeholders was that prevention measures should be compulsory and under the shared responsibility of both food business operators and competent authority. Seventy-five percent of the respondents had recent experience with particular hazards and declared to have undertaken risk reduction measures. Incentives to implement measures were policy obligation and public health consequences whereas barriers were budgetary reasons and doubts about their effectiveness. However, there was not always a complete agreement between the perceived usefulness of risk prevention measures and their effective implementation, and conversely. No significant difference could be observed in the perceptions, attitudes and practices towards risk prevention between neither groups of stakeholders nor their fields of competency. The results are important for improving the risk communication process because the same issues can be emphasized when promoting risk prevention in the food chain regardless of the type of food sectors and the groups of stakeholders.
