The present study was conducted to develop predictive models for <i>Salmonella</i> spp. in grated carrots. The results showed that <i>Salmonella</i> spp. did not display growth at 5°C, but it grew in grated carrots at other temperatures (10, 15, 20, 25, and 37°C) for both inoculum levels. Also, the inoculum levels affected the growth of this pathogen in grated carrots when the storage temperatures ranged from 15 to 25°C. The theoretical minimum temperatures calculated using the Huang model were 3.48 and 5.79°C for inoculum levels of 10¹ and 10² CFU/g, respectively. The primary and secondary models performed well in terms of agreement between experimental and estimated values. Furthermore, compared to the Ratkowsky model, the theoretical minimum temperature was given a more reasonable value using the Huang model. The models developed in the present study will be a useful input for future quantitative microbial risk assessment to appraise the proliferation of <i>Salmonella</i> spp. in grated carrots throughout the production process, storage, and distribution.</p>","PeriodicalId":15814,"journal":{"name":"Journal of Food Safety","volume":"44 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141536938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While manual trimming has traditionally been employed to remove gastrointestinal contamination, Brazilian legislation allows the use of a carcass washing system as an alternative. This study aimed to establish and validate a protocol for the use of a chicken carcass washing system as a replacement for manual trimming in a major poultry processing facility in southern Brazil. The methodology followed international standards for microbial analysis such as total mesophilic counts and <i>Enterobacteriaceae</i>. Comparing contamination levels before and after treatments, significant reductions are seen. Manual trimming reduced contamination by 39.43% (gastric), 53% (fecal), and 50% (biliary). Washing achieved greater reductions, with a 96.37% drop in gastric contamination and complete elimination (100%) of fecal contamination. These results met statistical significance. Both procedures reduced contamination levels. Manual trimming maintained 50% of samples below the mean value without exceeding upper control limits (UCL). Washing increased the percentage of samples below the mean value from 46% to 54%, demonstrating its superior efficiency. For <i>Enterobacteriaceae</i>, trimming maintained 44% of samples below the mean value, and washing increased it from 46% to 48%.

Altogether, ED2 or ED4 can potentially reduce sodium nitrite usage by 83% while preventing lipid oxidation and antimicrobial effects, thereby effectively maintaining sausage product stability.

Its presence is a major concern for both consumers and regulatory bodies due to its potential carcinogenic and mutagenic effects. Minimizing patulin concentration in apple juice products requires a multifaceted approach involving various stages of apple fruit production, from orchard management to processing and storage. This review explores the pre- and postharvest strategies associated with minimizing patulin concentration in apple juice products. It examines the role of good agricultural practices in reducing mold contamination in orchards and discusses the importance of proper postharvest handling, including fruit sorting and washing to remove contaminated apples before processing. During processing, factors such as temperature, pH, and processing time play crucial roles in minimizing patulin levels. Innovative processing technologies, such as pulsed electric fields (PEF), ultraviolet (UV) radiation, high-pressure processing, enzymatic, and chemical degradation have shown promise in reducing patulin concentration while preserving the sensory and nutritional quality of the juice. Furthermore, effective storage practices, such as maintaining proper temperature and humidity levels, are essential for preventing patulin formation during storage. Continuous monitoring and analytical testing for patulin content throughout the production chain are necessary to ensure compliance with regulatory standards and to guarantee the safety of apple juice products. Despite advancements in technology and production practices, challenges remain in effectively minimizing patulin concentration. These include the need for further research to develop more efficient detection methods, the adoption of sustainable and eco-friendly practices in orchard management, and the dissemination of knowledge and best practices to stakeholders across the apple juice supply chain. In conclusion, minimizing patulin concentration in apple juice products requires a holistic approach that integrates preventive measures, innovative processing technologies, and stringent quality control measures. By addressing these challenges, the apple juice industry can ensure the production of safe and high-quality products that meet regulatory standards and consumer expectations.</p>","PeriodicalId":15814,"journal":{"name":"Journal of Food Safety","volume":"44 3","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141073734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
