Meet the Outbreaks
Hammy Burgens
- Food Type:
- Hamburger
- Pathogen:
- Shigatoxigenic E. coli O157:H7
- Location:
- A restaurant chain across four states
- Impact:
- 732 people affected
- 178 permanently damaged
- 4 deaths
The real case
In 1993, a popular fast-food restaurant ran a promotion and discounted their hamburger sales across four states. Unfortunately, the restaurant received meat contaminated with a novel strain of bacteria known as shigatoxigenic E. coli. from their suppliers. The restaurant cooked the beef according to federal standards of the time, bringing the internal temperature to 140 °F (60 °C). However, this temperature was not high enough to kill the bacteria. The guideline has since been raised to 160 °F (71.1 °C).
How to prevent or mitigate
Recalling contaminated products;ensuring that the food is cooked to above 165 °F before freezing; following reheating guidelines.
