Grocery store associates in deli/bakery departments prepare and serve an increasing number of ready-to-eat (RTE) foods and full meals. The shift to more convenience foods and take-home meals highlights the need for effective food safety training programs in retail grocery establishments to prevent foodborne illness. Through qualitative and quantitative methods, food safety knowledge, training preferences, needs, and current practices of grocery stores deli/bakery food handlers in Southwest and Southern Virginia were explored. Deli employees (n = 78) completed a 34 question survey eliciting information on demographics, food safety training needs, preferences and knowledge. In an additional phase of this project, a subset of those originally surveyed (n = 15) were observed for food handling practices (6 h per person). Observational data collection focused on cross-contamination, glove use and hand washing. Most grocery store deli/bakery food handlers reported wanting frequent hands-on, interactive one-on-one training lasting less than 2 h. The target audience's largest knowledge gaps included correct temperatures for cooking, reheating and cooling foods. Observed behaviors did not correlate with food safety knowledge. For example, greater than 95% of participants reported using correct hand washing techniques; however, observational behavior data showed less than 50% of hand washing events observed were correct. Additionally, food handlers were observed not washing hands prior to putting gloves on as well as practicing bare hand contact with RTE foods. The creation of short, hands-on or interactive trainings for retail grocery food handlers that focuses on changing food handling and preparation behaviors may enhance the food handler's safe food handling practices.  相似文献

Youth are a unique audience for food safety education, in part due to low food safety knowledge. Although the effectiveness of such education has been explored for primary school and college students, no studies have assessed effectiveness among high school students specifically. We conducted a longitudinal intervention study in Ontario, Canada, between February and May 2015, to measure the baseline food safety knowledge and attitudes of high school students (n = 119; from 8 classes in 4 high schools), and determine whether these factors improved following in-class delivery of a provincial standardized food handler training program. Linear mixed effects regression models were used to model within-student changes in knowledge scores and attitudes over time (i.e., circa 2 and 12 weeks post-intervention), and to investigate associations with student characteristics. At baseline, knowledge and attitudes were poor. Following training, overall knowledge was significantly greater than at baseline, although at three months post-intervention only knowledge of safe times and temperatures for cooking and storing food remained significantly higher than baseline. Following training, students were significantly less interested in learning about how to avoid foodborne disease. Other attitudes, as well as knowledge of cross-contamination prevention and disinfection procedures, remained unchanged. These findings suggest that delivering existing food handler training programs within high schools may be a feasible mechanism for food safety educators to improve students' food safety knowledge, both overall and specific to safe times and temperatures, albeit potentially for short timeframes. Whether knowledge continues to decline beyond three months after training bears further investigation. As well, future research to investigate how students' actual food safety practices may change following such training, and whether improvements in knowledge translate into reduced foodborne disease risk, is warranted.  相似文献

The objectives of this study were 1. to identify the relationship of theoretical training with knowledge, attitudes, self-reported practices and observed practices and 2. to identify variables that influence observed practices. This study was cross-sectional and involved 183 randomly selected food handlers from different food businesses in Santos City, Brazil, as follows: street food kiosks, beach kiosks, restaurants, hospitals and school meal services. To evaluate knowledge, attitudes and self-reported practices, a structured questionnaire was used. Observed practices were evaluated using a checklist. A researcher observed and followed each food handler throughout the process of food handling/preparation during a workday. The majority of participants (68.3%) had participated in at least one food safety training session. The average percentage of correct answers on the knowledge questionnaire was 64%. Food handlers who had undergone training presented higher knowledge scores but did not differ from those who had not regarding attitudes, self-reported practices and observed practices. A regression model was used to study the variables associated with observed practices (p < 0.001). The variables related to observed practices were the knowledge score (β = 0.27, p < 0.01), experience (in years as a food handler) (β = 0.19, p = 0.01), the relationship between the number of meals and the number of food handlers (β = −0.19, p = 0.01), buildings and facilities adequacy (β = 0.20, p = 0.01) and the presence of a nutritionist (β = 0.42, p < 0.001). This study showed that training based on theoretical aspects is not related to the attitudes, self-reported practices and observed practices of Brazilian food handlers from different food services. However, training seems to be an effective tool for improving knowledge. The current wording of Brazilian legislation motivates food handlers to undergo training only for certification. Food safety laws should not only require certification but also enable the establishment of policies to monitor and ensure the adequacy of food services.  相似文献

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.  相似文献

The objectives of this study were: 1) identify the state anxiety, trait anxiety levels and perceived stress levels of food handlers and; 2) Verify the association of these scores with food safety variables like: food safety knowledge, attitudes, practices and with job characteristics. This study involved 183 randomly selected food handlers from different food businesses in Santos city, Brazil, as follows: street food kiosks, beach kiosks, restaurants, hospitals and school meal services. To evaluate knowledge, attitudes and self-reported practices, a structured questionnaire was used. Observed practices were evaluated using a checklist. The State Trait Anxiety Inventory – STAI was applied to assess the levels of state and trait anxiety with a score range from 10 to 80. To evaluate stress the Perceived Stress Questionnaire – PSQ was used with a score range from zero to one. Food handlers presented 39.22; 10.1 (mean; standard deviation) of state anxiety score, 39.58; 9.6 of trait anxiety score and a perceived stress score of 0.36; 0.09. Observed practices presented a weak negative correlation with state anxiety (r = −0.26; p = 0.014) but not with trait anxiety (r = −0.18; p = 0.09) and stress (r = 0.03; p = 0.78). Using generalized linear models were observed that a higher stress level, trait anxiety and state anxiety were found in food handlers who do not participated in food safety training and with lower knowledge scores of food safety. These findings show that training can not only improve knowledge but possibly empower food handlers, increase their self-efficacy and reduce anxiety and stress levels.  相似文献

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.  相似文献

Campylobacter remains the most commonly reported zoonotic agent worldwide. Reducing the concentration of Campylobacter on chicken meat is seen as the most efficient strategy to diminish the number of human campylobacteriosis cases. Analysis of risk factors related to characteristics of broiler batches and processing conditions could, however, not fully explain differences in impact of processing on contamination levels between slaughterhouses. Our study aimed at investigating whether compliance of food handlers with procedures on setting and controlling evisceration process parameters could explain differences in microbial concentrations on carcasses between slaughterhouses. The study was conducted in two commercial broiler chicken slaughterhouses. Analysis of documentation provided insight in the adequacy of procedures, and observational studies revealed insight in compliance with procedures by using a set of criteria for evisceration control. The frequency of carcasses with visible faecal contamination was counted and Escherichia coli concentrations on carcasses classified based on visible contamination was analysed. E. coli was found to be a valid indicator for Campylobacter during evisceration. Food handlers' knowledge, attitude and practices related to evisceration control tasks were analysed based on a validated questionnaire. Documentation analysis revealed obvious differences in the procedures between slaughterhouses. The observation study revealed that in the slaughterhouse with advanced procedures, the food handlers more often complied with these procedures and a lower frequency of carcasses with visible faecal contamination was observed. Carcasses contaminated with visible faecal spots, even at a low level, carried significantly higher concentrations of E. coli than visibly clean carcasses. Food handlers in both slaughterhouses revealed a good knowledge level. The attitude of food handlers differed between slaughterhouses. In one slaughterhouse, where food handlers complied more frequently with procedures their attitude was at a good level, and practices at good and moderate levels. In the other slaughterhouse the attitude of food handlers was at moderate level and practices at moderate and poor levels. In conclusion, the results from our case study suggest that management factors like availability of adequate monitoring procedures and food handlers' compliance with these procedures may influence the bacterial concentrations on carcasses. Our study demonstrated that compliance with procedures differed between slaughterhouses, and might be associated with faecal contamination of carcasses and thus with higher bacterial concentrations. These results suggest that managerial improvements, supervising and motivating food handlers could be an important control point. To validate the observed relation between compliance with procedures and contamination of carcasses, an intervention study is needed.  相似文献

The present cross sectional study was conducted on 811 Saudi women to evaluate their food safety knowledge and practices and explore factors affecting them. They reported better food safety practices than knowledge in overall food safety and all parameters except cooking. Personal hygiene was the parameter where they reported higher mean knowledge and practice (63.4% and 73.8%; respectively) with the lowest mean knowledge score in utensils and equipment (49.8%) whereas the lowest mean practice (60.2%) was in cooking. Saudi women with higher studies and those with 60 years and more showed higher mean knowledge and practice score in overall food safety and most parameters than those in other educational levels or age groups with significant variations (P < 0.05) among different educational levels except in practicing personal hygiene. Working women showed higher mean knowledge and practice than non working in all parameters with significant variation between their mean knowledge scores except in personal hygiene. Launching a food safety education program and repeating it at specific intervals is recommended.  相似文献

Organizational culture is defined by dimensions and characteristics that can be used to measure food safety culture in food manufacturing through a food safety maturity model. Maturity models from quality, health care, and information technology have been used since early 1970 and this work presents a novel food safety culture maturity model with five capability areas and food safety pinpointed behaviours specific to functions and levels in a food manufacturing company. A survey tool linked to the model is used to measure a company's position within the maturity model framework. The method was tested with a Canadian food manufacturer and proved valuable to measure food safety culture across the five capability areas, which provides the manufacturer with a map for prioritizing future efforts to strengthen food safety culture.  相似文献

The changing food safety standards, stricter sanitary and phyto-sanitary requirements and improved global product norms trigger the necessity to improve legislative network of a country based on codex Hazard Analysis Critical Control Point (HACCP). Due to multiplicity of laws in a majority of developing nations processed food industry is facing a major threat for survival and growth. In India nine different ministries were involved in controlling this area. Food Safety and Standards Act was established to integrate the food safety laws in India, in-order-to systematically and scientifically re-orient food processing and manufacturing industry from regulation to self-compliance. In this study, authors' focuses on issues related to the food legislation enforced time to time based on international scenario and trade. This study brings out the fact that more holistic approach is seen in new scientific standard development and covers a wider variety of products including functional food, novel food and beverages. The basic requirements of food hygiene and Good Manufacturing Practice (GMP) practices as described by codex are important for any national food safety control. However, the study concludes that there exists a gap in infrastructure and risk-based approach in the both implementation and enforcement. The study also provides the SWOT analysis of Indian legislative model and recommendation for improvement.  相似文献

In order to improve the safety of seafood in domestic distribution chains in Vietnam, a better understanding of factors affecting the practices of seafood distributors is necessary. The objective of this research was to identify the factors affecting the food safety practices among distributors in three major sites. A mixed methods design including qualitative and quantitative methods was used. Questionnaires were completed by 180 workers at various points of the seafood distribution chain. The survey revealed poor knowledge of food safety and hygiene amongst distributors and ineffective use of food safety management practices throughout the domestic seafood distribution chains. There was generally a low level of compliance with food safety regulations. One potentially positive outcome is that seafood distributors are concerned about critical feedbacks and complaints from consumers. Therefore, improving consumer knowledge may have a positive impact on food safety practices in the domestic seafood distribution chains.  相似文献

Based on 1553 media reports on food safety scandals and concerns, we conducted an aggregated analysis on economically motivated food frauds and adulterations in China. A systematic approach is used to analyze the country's food safety concern in terms of fraud type, implicated foods, adulterants, contaminants and abnormal conditions, and concerned food sources. This study indicate that economically motivated food fraud and adulteration was an emerging and serious food safety problem in China. The results of the study can be used not only to analyze food safety risks but also to prioritize target areas for food policy-making and enforcement of food safety regulation.  相似文献

This study was conducted in the northern region of Peninsular Malaysia to examine the characteristics of food companies, their food safety improvement activities, motives and external factors that influenced their decision on implementing the Malaysian food safety system (MeSTI). The study employs a survey questionnaire which was distributed to the respondents during food safety seminars, workshops and meetings. A total of 89 completed questionnaires were returned. The results indicated that the main motive for adopting a food safety system was to improve product quality, while external factors influencing food safety adoption was consumer awareness of food safety and the intension of industry to increase customer confidence. The results of the study suggest that, compared with perceptions toward food safety, there is significant difference in the motives to improve product quality, lowering the risk of compromising food safety and extending their market to foreign country among different groups in the food industry. The external factors influencing food safety adoption exhibit significant differences among the groups of perceptions in increasing customer confidence.  相似文献

Listeria monocytogenes is an important foodborne pathogen that may be transmitted from the food-processing environment to food; however, the ecology and interaction of this organism with microbial residents on surfaces within the food industry is not well understood. The current study was undertaken to investigate the influence of Listeria innocua on the growth and attachment of L. monocytogenes to stainless steel or aluminum surfaces at 23 °C. When grown in broth as a mixed culture, L. innocua reached a higher cell count at 24 h than did L. monocytogenes. Attachment was evaluated by placing an aliquot containing 103 CFU/ml of L. innocua and 103 CFU/ml of L. monocytogenes on the coupons and by quantifying attached cells after 24 and 72 h. Attachment of L. monocytogenes was decreased by the presence of L. innocua. When compared to L. monocytogenes alone, there was a significant reduction of attachment of L. monocytogenes at 24 and 72 h on stainless steel and 72 h on aluminum surface when L. innocua was added at the same time. L. innocua exhibited an effect on the attachment of L. monocytogenes, increasing our knowledge of the behavior of L. monocytogenes in the presence of another Listeria species.  相似文献

Knowing which products and hazards to monitor along the food supply chain is crucial for ensuring food safety. In this study, we developed a model to predict which types of herbs and spices products and food safety hazards should preferentially be monitored at each level of the supply chain (suppliers, border inspection points, market and consumers). A Bayesian Network method was used to develop a model based on notifications reported in the Rapid Alert System for Food and Feed and the database of the Dutch national monitoring program for chemical contaminants in food and feed over the period 2005–2014. The model was constructed by randomly selecting ca. 80% of the 3126 data records and validated using the remaining ca. 20% of the records. Model validation showed that the prediction accuracy was higher than 85%. Results showed that the sampling plan is closely related to the place where the products are checked along the supply chain, the products and the country of origin. Our approach of integrating different data sources and considering the entire supply chain can support industry and authorities at border inspection points and at all control points along the herbs and spices supply chain in setting priorities for their monitoring program.  相似文献

A broad-range culture-independent method was developed and evaluated regarding its sensitivity of detection of pathogenic bacteria in spices and herbs, with focus on paprika powder. The method involved DNA extraction using cetyltrimethylammonium bromide (CTAB), 16S rDNA amplification using universal bacterial polymerase chain reaction, and high-throughput sequencing on Illumina MiSeq platform. The sensitivity of the method was evaluated with series of model samples contaminated at different levels with Salmonella enterica and Escherichia coli (as representatives of Gram-negative bacteria) and Staphylococcus aureus (as a representative of Gram-positive bacteria). For spices (paprika, black pepper), the method had a screening-level sensitivity with limits of detection in the range of 104–105 CFU/g, and a semi-quantitative response. Low sensitivity (LOD ≥107 CFU/g) was observed with herbs (oregano, parsley). The developed method demonstrated a good potential for microbiological screening of spices, with a prospect of further improvement of sensitivity based on progress in high-throughput sequencing technology.  相似文献

Afghanistan has significant competitive advantages in agribusiness. Much has been said about Afghanistan's unrealized potential in this sector over the years and many specialists have highlighted challenges in infrastructure, access to finance, and inadequate legislation as barriers to growth in the sector. Many have also pointed to its potential productivity increase as a way to help alleviate food security issues. With adequate access to finance and infrastructure, Afghanistan should in theory be a top exporting country in all agricultural sectors. The potential also exists for Afghanistan to be a top exporter of high-margin products like fruits, meat, dairy and vegetable processing. In order to realize this potential, however, stronger food safety control needs to be in place to export to markets. In Afghanistan, food safety practices are still based on experiences from the late 1970s. Companies face constant pressure from the crisis, market competition from importing companies, pricing pressure from retailers, and seemingly endless inspections from government bodies. In fact, there are three main state agencies (Ministry of Public Health, Ministry of Agriculture, Irrigation and Livestock, and Municipalities) that regularly inspect food companies, often performing the same functions and loading these already cash-strapped enterprises with unneeded administrative burden. There are still important issues to be addressed within the food safety system of Afghanistan, such as: complete harmonization of legislation with the regional (legislation and standards mainly), improvement of coordination among authorities; ability to ensure impartiality of inspection work; thorough training of inspectors and implementation of skills, especially towards risk-based inspection control; reform of sampling schemes for food of non-animal origin and imported food commodities; strengthening surveillance of foodborne diseases, control of adulterated foods; and supporting the introduction of self-inspection systems based on HACCP principles and good hygienic practices.  相似文献

The objective of the present study was to evaluate the development of food safety scores in school meal services during the application of a systematic intervention based on the knowledge, attitude and practice triad. A total of 68 public schools were included in the study. School meal services were assessed every three months with a checklist, which resulted in eight evaluations over two years. A program was developed and implemented in all the schools during this period that was comprised of three steps: 1) theoretical training, 2) implementation of action plans in situ and 3) weekly visits to motivate food handlers and monitor good practices. These steps were designed to promote changes in the attitudes and practices of food handlers. An ascending linear function was observed for the school meal services' general adequacy percentage over time. Positive developments were also observed regarding buildings and facilities, processes and procedures, distribution of meals, integrated pest management, water control, controls and records, health and safety of employees and equipment and utensils. Our results suggest that the proposed intervention strategy performs well in making school meal services conform to good practices and that strategies in this context should be permanent and continuous.  相似文献

Following the establishment of the Lebanese food safety authority (LFSA) in the food safety draft law, this study aims to find the appropriate food safety governance system in Lebanon in accordance with the risk analysis and the clauses of the World Trade Organization (WTO) Sanitary and Phytosanitary (SPS) Agreement. It describes the regulatory and institutional food safety governance system developed in USA, EU, Canada and France using inventory approach and in-depth interviews at institutional level to profit from their previous experience in this field. The findings indicate that Lebanon showed compliance with the clauses of the WTO but it will not be for the interest of Lebanon to join the WTO before it strengthens its infrastructure capacity at the institutional and stakeholders level through harmonization of the Risk Assessment (RA) and Risk Management (RM) at the institutional level and at all stages of the food chain. Lebanon should rely on bilateral and multilateral agreements by carrying out equivalence that fits his socio-economic situation based on RA. As it was shown in the studied countries, power given to the food safety authority depends on the willing of the country to adopt the political democratic approach or political scientific approach and RM and RA were not always functionally and institutionally separated. Lebanon within his political and socio-economical situation will meet constraints if he relies only on scientific justification, he should adopt the political democratic approach and ensure collaboration among RA agencies and RM at different levels.  相似文献

The growth of the global food trade has increased significantly over the last two decades. The purpose of this review paper is to compare imported food safety controls in Taiwan, Japan, the United States, and the European Union. Our key findings are: 1) imported food of animal and non-animal origin is by separate, competent authorities in Taiwan, Japan, and the US, whereas it is controlled by a single authority in the EU, 2) foreign facilities require registration in the US and Japan, 3) importing high-risk food in the EU, Taiwan and Japan requires the competent authority to inspect the food chain process and facilities in the third country, whereas a US FDA’s accredited third party auditor can do so in the US, 4) an advanced developed support systems for enabling the effectiveness and efficiency of imported food control can only be found in the EU and US. These findings may help the competent authorities responsible for imported food safety in Taiwan and the other countries to develop and enhance their own systems, not only to meet the international standards but importantly for the sake of public health protection.  相似文献
