Final answer:
The Salmonella outbreak was likely due to inadequate cleaning of a meat grinder's auger housing at a butcher shop, resulting in contamination of the raw ground beef used for steak tartare. Proper cleaning and cooking practices are crucial to preventing such foodborne illnesses.
Step-by-step explanation:
The cause of the Salmonella outbreak in Dodge County, Wisconsin, was likely due to improper sanitation of the meat grinder used for making the raw ground beef for steak tartare. While the employees of the butcher shop indicated that most parts of the grinder were cleaned and sanitized daily, the auger housing, secured with nuts and bolts, was not regularly removed and properly cleaned. Without thorough cleaning of all components, the grinder could harbor Salmonella bacteria, leading to contamination of the food prepared with it.
Consuming raw or undercooked ground beef, as well as other products like milk, juice, vegetables, sprouts, and water, if contaminated, can lead to foodborne illnesses. Typically, the most dangerous foodborne pathogens include certain serotypes of E. coli, Salmonella, Listeria, Campylobacter, and Vibrio, all of which are preventable with appropriate food handling, cooking, and sanitation practices.
