The Biggest Foodborne Illness Outbreaks in History

Foodborne illness outbreaks, sometimes the result of nationwide food recalls, affect hundreds to thousands of people every year. Many people get sick without knowing they’ve eaten contaminated food, which makes severe illness and death much more likely. This is a much more common occurrence than you might think. Recalls, and the widespread infections that prompt them, occur hundreds of times each year.
