Food safety: Fruits and vegetables The Symposium also featured projects that built upon our knowledge base to provide opportunities to fine-tune best practices: * Hazard analysis and risk assessment are currently your best tools for managing Cyclospora. Surveys of open water sources in California and Florida yielded about 10- percent presumptive Cyclospora positives. Follow on confirmation testing indicated these samples were largely genetically related species of Eimeria and Isospora [Ortega 2019]. Similar water sampling in Georgia yielded forty-seven presumptive Cyclospora positives yet confirmation testing showed these to be false positives [Mattioli 2019]. conducted in seven peach packinghouses revealed that in some of the facilities, lines washed and sanitized right after production ended and left till start-up the next morning surprisingly had higher aerobic plate counts than what was found during the production shift [Dawson 2019]. * A new tool to permit more effective temperature control. Think you are cooling your products properly? You might want to think again as surface temperatures are not always indicative of core produce temperatures. Low cost ($450-700) infrared cameras integrated into a cell phone permit reliable, non-contact, non-invasive, realtime measurement of core and surface product temperatures [Mis Solval 2020] to help control spoilage and pathogen growth. Infrared cameras can also enable identification of " hot spots " and permit better temperature control in distribution facilities. * Pay attention to your use of quat-based sanitizers. FDA has suggested operators rotate sanitizers to prevent pathogens from becoming tolerant to common quat-based sanitizers. An earlier CPS project suggested the development of genetically heritable tolerance is unlikely [Wiedmann 2019]. A new research project [Deng 2019] examined 25,000 strains of Lm isolated in U.S. food processing operations for the bcrABC gene which confers increased tolerance to quat-based sanitizers (benzalkonium chloride). 94.6-percent of the isolates were found to harbor the bcrABC gene. * Effective use of wash water disinfectants can help you control the risks represented by illness-causing human enteric viruses. The MS2 bacteriophage shares characteristics of the human enteric hepatitis A virus and can be used as a surrogate to study the efficacy CAKE PAN LINERS CUSTOM DIE CUT LINERS * Low minimums * No more greasing * Speeds production with minimal breakage * Many materials and colors available * Send us your pan at no charge for samples BAKING CUPS/ FLUTED LINERS * Auto detesting * High release silicon paper * Custom and stocked sizes * Random and register printing available.
