When it comes to raising babies, few things are cut and dried. Should babies sleep on their backs, or on their stomachs? Is this diaper dirty or clean? One thing, however, is clear: never allow a baby to eat honey. Why? Because for babies less than a year old it may contain poison in the form of botulism-causing bacteria.
Botulism results from a protein called botulin, produced by a particular strain of bacteria. Once inside the body it blocks the nerve cells that cause muscles to contract, resulting in
paralysis1. At worst, botulin can cause total paralysis leading to death.
Since botulism bacteria cannot survive in oxygen, they form
spores2 that lie
dormant3 until they're in an oxygen-free environment. For example, the oxygen-free insides of canned goods are prime breeding grounds for botulism. Unless such cans are heated properly to destroy the spores, they will
awaken4 and contaminate the food inside. That's why many cases of botulism occur after the victim has eaten canned food.
Honey normally doesn't come in cans, so what does this have to do with babies? When bees collect nectar from flowers, they incidentally pick up botulism spores that get mixed into their honey. Since adults and babies more than a year old have
fully5 developed immune systems and
intestinal6 bacteria that destroy the spores, eating honey is no problem. Lacking these safeguards, a baby that eats honey provides a perfect environment for the spores to
activate7 and
unleash8 their
toxin9. So keep your baby away from honey. Chances are she's already sweet enough just as she is.
