What type of food is typically associated with outbreaks of Bacillus cereus?

1. Pasta

2. Cooked Rice

3. Meat

4. Vegetables

The correct answer is: Cooked Rice

Bacillus cereus is a type of bacteria that can cause foodborne illness, and it is most commonly associated with starchy foods, particularly cooked rice. This organism is known for its ability to produce spores that can survive cooking temperatures. If cooked rice is left at room temperature for an extended period, these spores can germinate and produce toxins, which lead to food poisoning when consumed. When rice is cooked and held at unsafe temperatures, particularly in buffets or food service environments, it provides an ideal environment for Bacillus cereus to thrive. This is why cooked rice is often highlighted as a significant risk factor for outbreaks. The other food types listed may also be associated with various pathogens, but Bacillus cereus outbreaks are most prominently linked to improper handling and storage of cooked rice.
