Contaminated meals are especially dangerous for children because food - borne pathogens that may cause
only mild cramps in healthy adults can cripple and kill young people, whose immune systems are still being formed.
Side effects are pretty rare and usually
only occur when too much is taken, but are generally
mild and may include stomach aches and
cramps, nausea, vomiting,
mild skin rash, dizziness, itching and headache.
