Food Safety and Protecting Wyoming’s Health

More than 140 years ago Louis Pasteur showed the world that the growth of microorganisms was responsible for the spoilage of beverages such as milk, and that heating could markedly reduce such spoilage and resulting illness.

Since then, we’ve taken major steps forward to make our food safer, including wide use of pasteurization and safety standards. Over the years, these measures have helped protect the public from countless cases of sickness and have likely saved many lives. While not all foodborne disease has been eliminated, there is no doubt that many, many illnesses are prevented by our current protections. {read more}


Foodborne Disease - It does exist  

WDH Food and Waterborne Disease Summary 2003-2008



Raw Milk Statistics


  • Consumption of raw milk is the leading cause of Campylobacter outbreaks in Wyoming
  • WDH investigated 3 outbreaks (resulting in 18 illnesses) of Campylobacter associated with raw milk from 2003-2008; Isolated cases were also identified that were likely due to consumption of raw milk or milk products
    • In Laramie Co, a child developed severe disease (HUS) from E. coli  after consumption of raw goat’s milk (2009).
    • In Lincoln Co, a case of Campylobacter was reported who consumed raw cow’s milk (2010).
    • In Campbell Co, a case of Campylobacter was reported who consumed raw cow’s milk with a group.  WDH was unable to identify the others or the milk supplier (2010).
    • In Campbell Co, a case of Salmonellosis was reported who consumed raw milk while traveling to another state.

United States

  • U.S. 2006, 10 outbreaks linked to consumption of raw milk, caused by Campylobacter, E. coli, Salmonella, and Listeria  (CDC MMWR 2009; 58:609-15)
  • From 1993 to 2006, 69 outbreaks of human infection in U.S. resulting from consumption of raw milk were reported to CDC. These outbreaks included a total of 1,505 reported illnesses, 185 hospitalizations and 2 deaths. Because not all cases of foodborne illness are recognized and reported, the actual number of illnesses associated with raw milk likely is greater (

WDH Fact Sheet on Raw Milk Consumption

'Raw milk is known to transmit infectious diseases, and pasteurization is known to minimize risk.  Raw milk has NO benefit that would justify any increase in risk to children.'


American Academy of Pediatrics, AAP News, Vol 29: no 12

 The Infectious Disease Epidemiology Program has investigated many sporadic cases, clusters, and outbreaks of illness due to consumption of raw milk.  To read a summary of these investigations click here:
