How Safe Is Peanut Butter?
Peanut butter can be safely stored without refrigeration because it contains less than 1% moisture. It cannot
support the growth of bacteria or even drought-tolerant molds. Some people are allergic to peanuts and peanut
butter. Allergic reactions may include skin irritations such as rashes, hives and eczema. Gastrointestinal symptoms
may include nausea, vomiting and diarrhea. In rare cases, a potentially fatal condition called anaphylaxis
may occur. Persons with a known allergy to peanuts should avoid peanuts and peanut butter. Persons with a
known allergy to other legumes such as soy beans, peas, garbanzos (chickpeas), etc. may want to avoid peanut butter or exercise caution in its use. Peanut butter can be a choking hazard for young children. This can
be avoided by mixing peanut butter with thinner foods such as applesauce or mashed bananas.
