How long can the illness caused by Bacillus cereus last?

The illness caused by Bacillus cereus can last up to 24 hours. Bacillus cereus is a type of bacteria commonly associated with food poisoning, and it can produce two types of illness: one characterized by vomiting (often tied to the consumption of rice dishes) and the other associated with diarrhea (often linked to meat and vegetable dishes). The symptoms typically appear quickly, often within a few hours of consumption, but the duration of the illness can be relatively short, usually resolving within a day.

Unlike some other foodborne illnesses that may have longer-lasting effects, Bacillus cereus generally leads to a quicker resolution of symptoms, which explains why the illness can last up to 24 hours. This timeframe is important for food safety practices, as it signals the need for prompt management of food handling and storage to prevent such illnesses. Understanding this timeline helps food managers take proper precautions and ensures that food is safe for consumers.
