Effect of food safety training on behavior change of food handlers: A case of orange-fleshed sweetpotato purée processing in Kenya

Interventions in food business organisations to improve food safety culture: a rapid evidence assessment

The European Commission recently adopted Commission Regulation (EU) 2021/382 requiring food businesses to establish and provide evidence of a food safety culture (FSC). FSC incorporates management systems, risk perceptions, leadership, communication, environment and commitment to ensure food safety. This review (n = 20) investigates food safety interventions in food businesses to identify effective strategies to improve food safety practices and FSC, and to provide recommendations for improving FSC. Results found that most interventions focused on knowledge training and that workplace practical demonstrations produced the best outcomes. Similar training topics were used evidencing the existence of common training needs. Frequent training over longer time periods was most successful for behavioral change, yet no sustained behavioral change was reported, indicating that single knowledge-based interventions are insufficient, reinforcing repeated experiential learning to be incorporated into training. We suggest that FSC training should focus on FSC more broadly, rather than solely on knowledge training, and that management leadership skills in particular are important to ensure sustained positive change. This study contributes to knowledge by providing a summative overview of food safety interventions and how components of these may be used to enhance FSC in food businesses.

Food Safety and Management System Audits in Food Retail Chain Stores in Greece

The present study aimed to assess the performance of food safety management systems in food retail stores via audits to reveal potential areas of improvement and to find out possible corrective actions to suggest to the top management. Two cycles of on-site audits took place in 106 stores to assess the requirements and hygiene conditions. After the first cycle of audits, improvements were suggested to the top management, and a second cycle of audits took place after a reasonable time. In the checklist, we recorded the temperatures of retail refrigerators and the scores from the inspection of hygiene and HACCP documentation. In the A' audit, the percentage of stores that had higher temperatures than the critical limits was equal to 51%, and those temperatures occurred in the refrigerators for salads, followed by the refrigerators for deli meat, yogurts and desserts. In the B' audit, only the refrigerators for salads exhibited percentages that were statistically significant lower (p-value < 0.05), and the stores were improved after the audit. High percentages of high-scoring stores were observed in the A' and B' audit in the inspection of HACCP documentation, although there was not a statistically significant improvement observed (p-value > 0.05). In the hygiene inspection, statistically significant improvement with 95% confidence appeared for "Refrigerator's products appearance", "Storage cleanliness", and "Grocery shelf cleanliness". The highest number of non-conformities without statistically significant improvement was found for "Checking temperatures of the receiving products" and "Labeling of fruit store products", with the percentages being lower than 15% in both of the audit cycles. Many employees of the stores did not check and record the temperatures of receiving products from suppliers. In addition, the storage of spoiled products beneath fresh products for selling in the same refrigerator is not a good practice. Greater efforts must be made by top management and employees to maintain and distribute food products in the best and safest possible hygiene conditions.

Prevalence of Foodborne Bacterial Pathogens and Antibiotic Resistance Genes in Sweets from Local Markets in Iran

BACKGROUND

This study aimed to investigate the prevalences of some important antibiotic-resistance genes (ARGs) and foodborne bacterial pathogens in sweet samples collected from local markets in Iran.

METHODS

Forty sweet samples were collected. Foodborne pathogens and ARGs were detected in the sweet samples by conventional and multiplex PCR assays using species-specific primers.

RESULTS

Staphylococcus aureus, Cronobacter sakazakii, Shigella spp., Campylobacter jejuni, and Campylobacter coli were detected and identified in 47.5%, 20%, 45%, 5%, and 30% of the sweet samples, respectively. We found S. aureus and Shigella spp. were the most prevalent bacterial pathogens. S. aureus was found to be the most frequent pathogenic bacteria profiled in these samples. We also found a significant correlation between the presence of C. coli and Cr. sakazakii. We detected the blaSHV resistance gene in 97.5% of the sweet samples; however, blaTEM was detected in only one sample (2.5%).

CONCLUSIONS

Regarding these results, we suggest preventive strategies such as implementing automation of food processing; monitoring the personal hygiene and health of food handlers, and testing regularly for antibiotic resistance in raw materials and products.

Avian campylobacteriosis, prevalence, sources, hazards, antibiotic resistance, poultry meat contamination, and control measures: a comprehensive review

Avian campylobacteriosis is a vandal infection that poses human health hazards. Campylobacter is usually colonized in the avian gut revealing mild signs in the infected birds, but retail chicken carcasses have high contamination levels of Campylobacter spp. Consequently, the contaminated avian products constitute the main source of human infection with campylobacteriosis and result in severe clinical symptoms such as diarrhea, abdominal pain, spasm, and deaths in sensitive cases. Thus, the current review aims to shed light on the prevalence of Campylobacter in broiler chickens, Campylobacter colonization, bird immunity against Campylobacter, sources of poultry infection, antibiotic resistance, poultry meat contamination, human health hazard, and the use of standard antimicrobial technology during the chicken processing of possible control strategies to overcome such problems.

Development of an Educational Gamification Strategy to Enhance the Food Safety Practices of Family Farmers in Public Food Markets of Northeast Brazil: A Case Study

This study aimed to develop an educational gamification strategy to enhance the food safety practices of family farmers in public food markets in a city in Northeastern Brazil (João Pessoa, PB, Brazil). A good manufacturing practices (GMP) checklist was used to verify hygienic-sanitary conditions in the food markets. Educational game tools addressing foodborne diseases and GMP with information about the prevention of foodborne diseases, good food handling practices, and safe food storage were developed. Pre- and post-training assessments were done to evaluate food handlers' knowledge and food safety practices. Microbiological parameters of food samples were analyzed before and two months after the training. Results indicated unsatisfactory hygiene conditions in the examined food markets. There was a very strong positive correlation between "implementation of GMP" and "production and process controls" (R = 0.95; p ≤ 0.05) and between "production and process controls" and "hygiene habits of handlers" (R = 0.92; p ≤0.05). There was no homogeneity between answers before and after the training for the knowledge of family farmers regarding "prevention of foodborne diseases" and "safe food handling". There were improvements in the measured microbiological parameters of foods sold by family farmers after the application of the developed educational gamification training. These results showed the developed educational game-based strategy as being effective in raising awareness of hygienic sanitary practices, helping to promote food safety, and reducing risks for the consumers of street foods at family farmers' markets.

Food Safety Behaviours among Food Handlers in Different Food Service Establishments in Montenegro

Foodborne diseases in food facilities are a major public health problem, due mostly to the limited surveillance and educational level of food-handling workers. This study was conducted in 220 food service locations in Montenegro. Participants’ behaviour was assessed by a survey using the specifically designed structured questionnaire, administered before and after the training. To determine the effect of the training on the performance of food handlers, a microbiological analysis of food contact surfaces and food handlers’ hands was also performed. The behaviour of food handlers, viewed as a whole, is unacceptable. There was a statistically significant difference (<0.05) among participants who completed catering school compared with those who did not, regarding hand washing. The type of facility in which participants worked (restaurant, bakery, or pastry shop) revealed statistically significant differences (<0.05) in relation to hand washing, that is, restaurant employees had better habits than those from bakeries and pastry shops. Before the training, participants showed acceptable behaviour regarding hand hygiene, but it was much better after the training. Results of microbiological analyses of food contact surfaces and food handlers’ hands indicated better results after the education, especially with regard to hand swabs. The results of this study indicate the importance of education to improve food handling practices among food handlers, which might also decrease the possibilities for contamination of food.

Food Safety Governance in the Age of COVID-19: How Does Employees' Attitude on Public-Private Governance System Affect Their Willingness to Blow the Whistle on Food Violations?

Online food delivery increases dramatically during the COVID-19 era and has grown into a global marketplace worth more than $150 billion dollars, necessitating a more effective and responsive governance system. Public-private governance systems with whistleblowing to the public are seen as an effective tool for addressing the formidable challenges of food security in modern society. Accordingly, this study aims to explore the determinants of whistleblowing intentions and to propose policy policies for the whistleblowing system to fully utilize the advantages of public-private governance systems. Through empirical research, this paper finds that employees' perceived effectiveness of government authorities, as well as their familiarity with whistleblowing systems, positively affect their intentions to blow the whistle. However, the whistleblowing intent of restaurant employees is adversely affected by the online platform's focus. The root cause lies in the employee's trust in both the government sector and corporate sector. This study thus argues that a suite of measures to promote individual trust in public-private governance systems is desired and that this is an effective means of better mitigating food safety governance challenges in terms of capacity and resources.
