Jack in the Box
In 1993, 732 people were affected by one of the most notorious and tragic cases of food poisoning in US history. Jack in the Box, a fast-food hamburger chain, sold hamburgers with under-cooked beef patties that infected many customers with E. coli bacteria. The outbreak involved 73 restaurants across the US in the states of Idaho, Washington, Nevada and California. Sadly, the under-cooked burger patties were responsible for the deaths of 4 children and the serious injury of 178 other victims, including permanent kidney and brain damage.
Following the 1993 Jack in the Box outbreak, the US has adopted a zero-tolerance policy when it comes to E. coli and infection rates have reportedly since lowered.
