Between 2007 and 2016 there were 144 outbreaks connected to raw milk consumption in the United States. Because raw milk production skips the pasteurization process, the germs that are normally removed remain in the milk product. Exposure to raw milk containing harmful germs poses a threat of infection, resulting from bacteria including "Camplyobacter", "Cryptosporidium", "E. coli", "Listeria", and "Salmonella". Additionally, depending on the severity of infection, there may be further threat to human health. Infection has the potential to induce serious illness such as Guillain-Barré syndrome and Hemolytic Uremic Syndrome (HUS). Because of the vulnerability of developing and degrading immune systems, children, pregnant women, the elderly, and those who are immunocompromised are at a heightened risk of experiencing infection from raw milk consumption.
