The warmth of the summer sun can do wonders for your spirits, but it can also promote the growth of dangerous bacteria in food. You can keep the good memories of summer picnics by preventing food poisoning and the symptoms that could upset your summer fun. Food poisoning symptoms include diarrhea, vomiting, stomach ache, and possibly fever. Most cases of food poisoning are mild and don't require hospitalization.
Heat is especially bad for eggs.
Carefully refrigerate foods that contain lightly cooked eggs, including cream pies. Even hard-boiled eggs and egg rich foods should not be left out of the refrigerator for more than two hours. Don't eat raw meat or eggs or drink unpasteurized milk. That kills the spores that can produce the deadly toxin that causes botulism. Boiling vegetables before eating them also kills the toxin.
