Journal of Infectious Disease. The outbreak occurred in Vermont and New Hampshire. The implicated milk was likely contaminated post pasteurization when it was filled into milk bottles rinsed by untreated well-water. Well water had high coliform counts, which suggested possible fecal contamination and possible Y. Reference: Olsen, S. Ying, M. Davis, M. Deasy, B. Holland, L. Lampietro, M. Baysinger, F. Sassano, L.

Emerging Infectious Diseases. Outbreak investigation indicated that the milk processing plant had several violations of sanitary standards that could have resulted in the contamination of milk after pasteurization.
Typhimurium obtained during the outbreak period were outbreak related strains. Reference: Yuan, J. Accessed During investigation, it was noted that pasteurized milk produced before the outbreak had high bacteria counts.
In addition, about different C. These observations suggested that either the starting raw milk had very high levels of pathogen contamination from the dairy environment or the milk was contaminated post pasteurization. Outbreak of Listeria monocytogenes infections associated with pasteurized milk from a local dairy — Massachusetts, The pasteurized milk was most likely contaminated post pasteurization.
The dairy plant had poor sanitation practices and several environmental samples obtained at the plant were positive for L. The sanitary procedures described in a food safety plan under HACCP might help to reduce the probability of raw milk contamination but they will not ensure that raw milk is pathogen-free. As the preceding discussion demonstrates, raw milk does not naturally kill pathogens of concern. Further, testing raw milk for the various pathogens prior to consumption can not be used as an alternative to pasteurization.
The potential pathogens present in raw milk can be diverse, variable, and unpredictable. It is simply impossible to test every single batch of raw milk for every single pathogen prior to human consumption. More importantly, the inability of a method to detect pathogens does not indicate the absence of pathogens Oliver et al. There is no visual or sensory indicator for the presence of pathogen. Typical milk quality indicators, such as standard plate counts and somatic cell counts, do not provide information on the presence or absence of pathogens.
Seemingly high quality raw milk based on these routine quality indicators can still contain pathogen Van Kessel et al. HACCP ensures product safety through process control and not by finished product testing. HACCP has been considered possible for chemical and physical hazard controls in farm settings.
However, HACCP is not effective or even possible in farm settings for biological hazards, including pathogens Cullor, ; Sperber, Cullor indicated that potential biological hazards that may exist on the dairy farms do not have well-known critical control points. Since establishing critical control points is one of the most important aspects of HACCP, without well-known critical control points, HACCP simply does not work for pathogen control for raw milk production on the farm.
Organic Pastures is an example of a raw milk producer with a HACCP plan whose milk has been found to contain pathogens. In , raw milk contaminated with E. None of the claims made by the raw milk advocates that we have examined for you can withstand scientific scrutiny. It is these very same sub-groups of the population, however, that are most at risk for becoming ill or even dying from foodborne illness as a result of consuming adulterated raw milk.

Please become a member, today! Why is Raw Milk So Good? Raw Milk Contains: High levels of calcium and other minerals , and the enzymes necessary to metabolize these minerals. Those enzymes are destroyed in the pasteurization process. An abundance of beneficial bacteria that can rebalance a digestive system unable to process many foods, and can restore the immune system.
These good bacteria help produce and assimilate vitamins and minerals, fight off illnesses, and regulate bodily processes. Pasteurization destroys all bacteria in milk. Water- and fat-soluble vitamins, two-thirds or more of which are destroyed during pasteurization. Vitamins B6 and B12 are almost entirely destroyed during pasteurization. Pasteurized reduced-fat or skim milk is an ineffective source of calcium. The Design Story.
