Food safety knowledge and practices of food handlers,head chefs and managers in hotels' restaurants of Salvador,Brazil

This study aimed to assess the knowledge level, attitudes and practices of food handlers, and knowledge and practices of head chefs and managers in hotels' restaurants of Salvador, Brazil. Data collection was done through the application of interviews with 265 food handlers and with 32 head chefs and managers. In addition, the influence of the presence of nutritionist in restaurants was evaluated. The results showed that 88.0%, 96.6% and 76.0% of handlers had knowledge, attitudes and practices appropriate for personal hygiene, respectively. However, some errors were observed such as the non-use of disposable gloves when handling or distributing food (39.6%), tasting food with their hands (28.7%), and usually talking while handling food (52.5%). Statistical analysis did not indicate a significant association between the knowledge, attitudes and self-reported practices by handlers. However, it was found association between handlers that presented good satisfaction with the job and handlers that introduced appropriate practices. Regarding to chefs and managers, the results indicate that the knowledge was unsatisfactory, even 75% of respondents have training certificate in food safety. A significant percentage of respondents were unaware of the legislation adopted in restaurants (37.5%), and only 43.8% of them knew the recommended cooling temperature for food preservation. However, adequate practices to reduce cross-contamination was observed. Still, the presence of the nutritionist in restaurants influenced positively on the adoption of the current legislation in hotels' restaurants, as well as in the participation of the handlers in training, showing in this way the creation of a positive culture among the handlers.     

Modeling the transmission of livestock associated methicillin-resistant Staphylococcus aureus along the pig slaughter line

The study introduces a new approach for a qualitative transmission assessment of MRSA throughout the pig slaughter process. Based on prevalence data found in literature the MRSA contamination and elimination rates of each individual slaughter step were estimated. The rates were used to set up a Monte Carlo simulation for modeling the propagation of MRSA along the process chain and to quantify the impact of a variable initial prevalence on the outcome prevalence of the carcasses. Sensitivity analyses for the model as well as three different scenarios were performed to estimate the impact of cross contamination during slaughter and to determine the process stages where hygiene interventions are most effective.Regardless of the initial extent of MRSA contamination low outcome prevalences ranging between 0.15 and 1.15% were achieved among pig carcasses indicating that the pig slaughter chain generally includes process steps with the capacity to limit carcass contamination. Especially scalding and singeing can lead to a significant reduction of superficial MRSA contamination during the first half of the slaughter process. Nevertheless, scenario analyses showed that the low MRSA outcome prevalence can only be guaranteed if recontamination during the ongoing slaughter process is obviated. In order to ensure a low MRSA load on pig carcasses at the end of slaughter the abattoir should primarily concentrate on controlling the process parameters of scalding and singeing and avoiding recontamination at subsequent process steps.     

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.     

Rutin inhibits mono and multi-species biofilm formation by foodborne drug resistant Escherichia coli and Staphylococcus aureus

Considering the role of biofilm in food spoilage and the food industry, inhibition of biofilm formation by natural agents is expected to be safe and could also enhance the efficacy of other antimicrobial strategies for controlling microbial food spoilage. Plant flavonoids are known for their diverse biological activity including antimicrobial. Therefore, rutin was investigated for its biofilm inhibitory activity at sub-minimum inhibitory concentrations (sub-MICs) values against common foodborne pathogens (Escherichia coli and Staphylococcus aureus). Minimum inhibitory concentrations (MIC) ranged from 400 to 1600 μg/ml against the selected strains. Sub-MICs (1/16 × MIC to 1/2 × MIC) were used to assess the inhibition of biofilm formed by E. coli and S. aureus in microtitre plate assay. Mono strain biofilm formation by Escherichia coli and Staphylococcus aureus was greatly reduced by rutin at their respective 1/2 × MIC. For multi-species (E. coli: and S. aureus) biofilm formation, the reduction in biofilm production was concentration dependent. No significant bacteria mass reduction was recorded for any sub-MIC. SEM images of biofilm inhibition on steel chips confirmed the reduction in number of microcolonies. Exopolysaccharide production responsible for adherence and maturation of biofilms was also significantly (p ≤ 0.05) reduced at respective concentrations of rutin in tested strains. To the best of our knowledge, this is the first study describing the effect of flavonoid, rutin on multi-species biofilms consisting of S. aureus and E. coli. Findings of the study indicate a potential application of rutin in the prevention of biofilm on industrial equipment and food contact surfaces and prevent food contamination and spoilage.     

Street food on the coast of Salvador,Bahia, Brazil: A study from the socioeconomic and food safety perspectives

Street food includes various food items and drinks largely sold in public places, including leisure areas such as beaches. Despite the prevalence at this activity studies made within this scenario are few. Therefore, this study sought to characterize street food commercialization on the Salvador coast in Bahia, Brazil based on the socioeconomic, labor, and food safety perspectives. An exploratory and quantitative study was conducted on 14 beaches using questionnaires addressing the following areas: the socio-demographic characteristics of the food vendors, characteristics of the work, and hygienic and sanitary conditions of the activity. Our study included 247 food vendors with an average age of 40.3 years, of whom 55.9% were women, and 48.7% had completed an elementary education or less. The median time spent working in street food vending was nine years, and the average working day for the participants was 8.3 Furthermore, 46.2% of the participants worked only on weekends and 72.0% declared that their family income was between one and three times the minimum wage, of whom 29.1% had revenue from a source other than street food vending. Most of the vendor locations were fixed (57.5%), and the products sold were typically obtained from supermarkets (48.1%), suppliers (36.8%), and street markets (36.0%). Prepared food items were the most common (61.6%), although mineral water/soft drinks (35.8%) and beer (35.2%) were also commonly sold items, followed by acarajé (21.9%), coconut water (19.0%), fried fish (14.2%), and abará (12.5%). Only 38.3% of the perishable food items were kept in cooling containers. Of the interviewed individuals, 22.6% declared that they did not sanitize their hands when working, whereas 80.2% admitted to handling food and money simultaneously. Our study reveals the socioeconomic importance of the street food sector as well as the poor hygienic conditions of most street food vendor operations.     

Food handlers’ knowledge on food hygiene: The case of a catering company in Portugal

The aim of this study was to assess the food hygiene knowledge of professional food handlers from an institutional catering company which manufactures and distributes meals to the canteens of schools, kindergartens and nursing homes in Portugal. A total of 101 food handlers from 18 geographically distributed business units were assessed. Data collection employed a previously used, multiple-choice questionnaire, aimed at exploring the food safety knowledge and practices of individual respondents. The average score of questions answered correctly was 13 out of 23 (56.5%) with a standard deviation (SD) of 3.22. However, the percentage of correct answers varies with the issues questioned, being significantly lower on issues such as temperature control (p < 0.001) and sources of contamination/high-risk foods (p < 0.001). The level of knowledge was influenced by the level of formal education (p = 0.025) of respondents. The results reinforce the importance of conducting a preliminary assessment of training needs and evaluating the effectiveness of training.     

Vending machines: Food safety and quality assessment focused on food handlers and the variables involved in the industry

The purpose of this paper was to analyse the quality and safety parameters of food products sold in vending machines. A hygienic-sanitary assessment was conducted on 338 vending machines located on the island of Gran Canaria. Hygiene Assessment System (HAS) surveys, food handler examinations and microbiological (processed food and water) and physicochemical (water) controls were applied, permitting evaluation through the identification of the main risks and/or hazards of the hygienic-sanitary quality of the products sold in vending machines.Despite the positive results obtained from the HAS surveys applied to all the vending machines, achieving a total mean score of 87.6 ± 7.5 out of 100, the microbiological analysis showed that 5.7% of the 105 food samples were contaminated with Listeria monocytogenes, while Salmonella spp., Escherichia coli and Staphylococcus aureus were below the legally permitted limits. The lack of vehicles able to transport perishable food at correct temperatures (<8 °C) and the fact that some refrigerated vending machines were not at an ideal cooling temperature may have contributed to these values.The assessment tools used in this study revealed hygienic deficiencies in the transportation and microbiological quality of the products, despite the favourable results obtained in the HAS surveys and food handler examinations, indicating that this relationship should be the subject of further study to improve its usefulness in the field of Hazard Analysis and Critical Control Points.     

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.     

Food safety knowledge among food service staff in hospitals in Jordan

This study aimed to measure food safety knowledge among food service staff in hospitals in Jordan. A total of 532 food service personal (dietitians, cooks and food workers) from 37 hospitals (public, private, and university hospitals) were conveniently selected to participate in this cross sectional study. The participants completed a questionnaire composed of two parts (general characteristics and food safety knowledge). The overall food safety knowledge of food service staff is fair with a mean score of 56.3 out of 90 points (62.5%). Respondents had sufficient knowledge on “cross contamination prevention and sanitation” aspect, while they had very poor to good knowledge on “foodborne pathogens and related symptoms and illnesses”, “safe storage, thawing, cooking, holding and reheating of the foods”, “health problems that would affect food safety” and “personal hygiene” aspects. There were no significant associations between the total food safety knowledge score and age, educational level, marital status, income, experience, nature of work and attending course(s) on food safety. Respondents from public hospitals and who believed that HACCP is not important for food safety had significantly lower food safety knowledge score than those from private sector (OR: 3.3, CI: 1.76–6.01) and those who believed that HACCP is important (OR: 3, CI: 1.64–5.36), respectively. Food workers and respondents who have experience ≤48 months had significantly lower food safety knowledge score than dietitians (OR: 2.6, CI: 1.33–5.2) and those who have experience > 48 months (OR: 1.9, CI: 1.06–3.51), respectively. There is an urgent need for tailored food safety education and training programs that improve food safety knowledge of food service staff in hospitals in Jordan.     

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.     

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.     

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.     

Tenacity of Bacillus cereus and Staphylococcus aureus in dried spices and herbs

Numerous studies examined the antimicrobial effects of spice and herb extracts, whereas little is known about the effects of dry condiments on the survival of microorganisms. This study investigated the impact of dried condiments on the survival of Bacillus cereus and B. thuringiensis spores as well as Staphylococcus aureus cells. In addition, the survival variability between different strains was evaluated. Condiments (allspice, basil, cinnamon, nutmeg, oregano, paprika, parsley and pepper) were artificially contaminated by a dry spiking method using sand as carrier matrix and as control. The results show that counts of B. cereus and B. thuringiensis spores (initial spore count 5.6 ± 0.2 log₁₀ cfu/g and 6.7 ± 0.1 log₁₀ cfu/g, respectively) did not decline significantly in all condiments over a period of 50 weeks. In contrast, in some of the spiked test materials, cell counts of S. aureus (initial cell count 8.1 ± 0.5 log₁₀ cfu/g) were reduced below the detection limit of 10 cfu/g within 10 weeks of storage. D values for S. aureus ranged between 5 and 31 days depending on the strain, condiment and initial contamination level. In conclusion, dried condiments may not affect the survival of spores but can significantly affect the survival of non-spore forming bacteria. As strain variability can occur, tenacity studies should be conducted including a variety of strains.     

Detection of methicillin-resistant Staphylococcus aureus in dairy cow farms

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most common pathogens causing nosocomial infections worldwide. Animal-associated MRSA hazard has been recently identified, but less information is currently available regarding MRSA in cattle. The aim of this study was to estimate the presence of MRSA in samples of bulk milk, environmental dust, conjunctival and nasal swabs of workers obtained from thirty dairy cow farms. A total of 200 S. aureus strains were identified using phenotypic and molecular approaches. Three other species (Staphylococcus epidermidis, Staphylococcus xylosus and Staphylococcus saprophyticus) were found. In five S. aureus strains isolated from environmental dust and one S. epidermidis strain derived from human samples, mecA gene was detected showing a specific fragment at 527 bp. Moreover, 66 S. aureus strains were distinguished by susceptibility to 15 antimicrobial agents. The highest resistance profile was ascribed to ampicillin, amoxicillin and penicillin G, both in workers and bulk milk samples. Generally, a multiple resistance to 4 up to 10 antibiotics was detected. S. aureus mecA⁺ strains and S. epidermidis mecA⁺ strain showed multiple resistance to 13 and 11 antibiotics, respectively. The obtained results suggested that the low number of MRSA strains, probably of human origin, was due to the appropriate hygienic practices adopted by the dairy cow farms.     

Development of conscious food handling in Hungarian school cafeterias

The last steps of food chain are particularly important, because this is when the food products reach the consumer. In the catering sector, the responsibility of food handlers are very high in the prevention of foodborne diseases. In this situation, the food handler's work must be conscious. This paper focuses on the issue of consciousness in food handling, which is the relationship between the level of knowledge and the implementation of right practice. The aim of this study is to establish a special food hygiene training model and measure its efficiency. The essence of the training model is to increase the consciousness of food handlers.Food hygiene training was tested at 33 school kitchens, where 145 staff participated. The program lasted for 6 months. Theoretical knowledge was evaluated, using self-administered tests, and food handling practice was measured through observation. Results before and after the intervention program were compared.Deficiencies in hygienic knowledge and in food handling practice were identified in seven areas. Significant increases were observed in theoretical knowledge in the areas of receiving (33.5%) and food waste (11.7%). With regards to the food handling practice, some remarkable positive changes were observed in the fields of storage (33.3%), dishwashing (24.7%), and cleaning (22.0%). Dishwashing, personal hygiene, and cleaning were the areas where such increases were observed, both in their knowledge and practice, that is, consciousness was increased in these areas.The parallel development of hygienic knowledge and food handling practice increased the consciousness in food handling, which is indispensable for ensuring safe food practices. Increasing consciousness make good practice instinctive in everyday work.     

Food safety regulatory model in India

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.     

Contamination of post-harvest poultry products with multidrug resistant Staphylococcus aureus in Maryland-Washington DC metro area

We investigated the prevalence of Staphylococcus aureus and multidrug including methicillin-resistant S. aureus (MRSA) in poultry retail meat samples from the Maryland-Washington DC metro area. A total of 24 S. aureus isolates were recovered from 96 whole poultry carcass samples and the prevalence of S. aureus were 25.0%, 14.29%, and 33.3% in retail poultry meats collected from farmers markets, organic and conventional retail supermarkets, respectively. Both single and multi-drug resistance isolates were detected in 58.3% (7/12) isolates from conventional retail meat products but none from farmers markets or organic retail meat isolates. Conventional retail meat isolates were found to be resistant to both erythromycin (50.0%) and tetracycline (58.3%). We also detected an MRSA isolate harboring mecA gene in conventional retail meat which showed co-resistance towards erythromycin, tetracycline, and vancomycin.     

Food safety in the domestic environment

The main purpose of this work was to evaluate the significance of food safety in domestic environments. In this study, several points in 15 houses (handles of doors, refrigerators and dishwashers, cooking stove knobs, surfaces of preparation of foods, taps and kitchen towels, as well as from domestic animals' feet that usually have access to the kitchen area, and WC knobs and taps) were sampled and tested for detection and quantification of Enterobacteriaceae, Staphylococcus coagulase-positive, Escherichia coli, Listeria spp. and Campylobacter spp. A questionnaire was also prepared and administered to the person responsible for domestic tasks in order to evaluate their experience of hygienic practices. The results showed a total of 125 Enterobacteriaceae spp. isolates, 86 Staphylococcus coagulase-positive isolates, 5 Listeria spp., 13 E. coli isolates and no Campylobacter spp. was found. Most of the isolates were found distributed by the entire house, with handles, knobs and domestic animals' feet being the points more contaminated. Also, there was no relation between the answers to the questionnaires administered and the microbiological results obtained. These results revealed the need to develop some education campaigns designed to educate consumers in good hygiene practices at home.     

Food safety and quality management regulatory systems in Afghanistan: Policy gaps,governance and barriers to success

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.     

Opinion of the food processors, wholesale and retail companies towards the Program for Product Quality Analysis in São Paulo, Brazil

This research seeks to identify the opinion of food manufacturing, wholesale and retail companies towards the Program for Product Quality Analysis in Brazil. Managers from 11 food manufacturing companies and six wholesalers and retailers from the State of São Paulo were interviewed. The results showed that there is a lack of knowledge of the official methodology adopted by the program. The food processors were concerned about the impact the divulging of the results of these analyses would have on the wholesalers and retailers. In addition, they contested the way in which the results were divulged. However the majority of the interviewees believed that the general effect of the program on the society was positive.
