Download or read book Scientific Criteria to Ensure Safe Food written by National Research Council and published by National Academies Press. This book was released on 2003-09-29 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food safety regulators face a daunting task: crafting food safety performance standards and systems that continue in the tradition of using the best available science to protect the health of the American public, while working within an increasingly antiquated and fragmented regulatory framework. Current food safety standards have been set over a period of years and under diverse circumstances, based on a host of scientific, legal, and practical constraints. Scientific Criteria to Ensure Safe Food lays the groundwork for creating new regulations that are consistent, reliable, and ensure the best protection for the health of American consumers. This book addresses the biggest concerns in food safetyâ€"including microbial disease surveillance plans, tools for establishing food safety criteria, and issues specific to meat, dairy, poultry, seafood, and produce. It provides a candid analysis of the problems with the current system, and outlines the major components of the task at hand: creating workable, streamlined food safety standards and practices.

Available in PDF, EPUB and Kindle. Book excerpt: Effective strategies for extending fluid milk product shelf-life by controlling bacterial growth are of economic interest to the dairy industry. To that end, the effects of addition of L-arginine, N[alpha]-lauroyl ethylester monochloride (LAE) on bacterial numbers in fluid milk products were measured. Specifically, LAE was added (125, 170, or 200 ppm) to conventionally homogenized and pasteurized 3.25% fat chocolate or unflavored milk products. The treated milks and corresponding controls were held at 6°C and plated on standard plate count (SPC) agar within 24 hours of processing and again at 7, 14, 17 and 21 d of storage. Bacterial numbers in all unflavored milk samples treated with LAE remained below the Pasteurized Milk Ordinance (PMO) limit of 4.3 log cfu/mL for the entire 21 days. Bacterial numbers in unflavored samples containing 170 and 200 ppm LAE were significantly lower than those in the untreated unflavored milk at d 17 and 21 post-processing. Specifically, bacterial numbers in the milk treated with 200 ppm LAE were 5.77 log cfu/mL lower than in untreated milk at 21 d post-processing. Bacterial numbers in chocolate milk treated with 200 ppm LAE were significantly lower than those in the untreated chocolate milk at d 14, 17 and 21. In chocolate milk treated with 200 ppm LAE, bacterial numbers were 0.9 log cfu/mL lower than in the untreated milk at 21 d post-processing. Our results show that addition of LAE to milk can reduce bacterial growth. LAE addition is more effective at controlling bacterial growth in unflavored milk than in chocolate milk. The dairy industry has a great deal of interest in tests that not only determine the quality of raw milk, but that will also help to predict the quality of the finished product processed from that raw milk. One test that has been used widely to test raw milk quality is the Preliminary Incubation (PI) test which stresses raw milk at 12.8 degrees C for 18 hours prior to enumeration. An elevated PI count has been used as an indicator that cleaning, sanitization and cooling practices on the farm are inadequate as well as an indicator of pasteurized product quality. Samples of raw milk and corresponding commercially pasteurized milk were obtained from four New York State (NYS) fluid milk processors over a one year time period from October 2007 through September 2008 to assess the overall quality of raw and pasteurized milk in NYS as well as to determine the accuracy of raw milk tests in predicting pasteurized product shelf life. Standard plate counts (SPC) and sensory quality from commercially pasteurized milk samples at day 17 post-pasteurization were compared to corresponding raw milk PI counts, with resulting R2 values of 0.2416 and 0.1007 respectively. When the confounding factor of post-pasteurization contamination (PPC) in the commercially pasteurized samples is accounted for, the R2 values for both PI versus day 17 SPC and PI versus day 17 sensory drop to 0.1972 and 0.0726 respectively. These results indicate that the PI count is not a good predictor of pasteurized milk quality, and while raw milk quality is an important factor in providing consumers with high quality product it appears that plant factors including PPC and processing conditions have a major impact on product quality. More research is needed to develop a test that can accurately and rapidly assess raw milk quality as it pertains to pasteurized product performance.
