Staphylococcal enterotoxin is a fast-acting bacterium that can cause people exposed to it to become sick as soon as 30 minutes after eating it. Unfortunately, thoroughly cooking the food does not prevent illness, and food-poisoning-like illnesses tend to start as soon as one to six hours after contaminated food is eaten.

So far, there are no reported illnesses due to the food. Anyone with questions or concerns is advised to contact customer service at (800) 638-0215.
