The concern over honey is botulism and it applies only to uncooked honey.
Clostridium botulinum bacteria are found in about 10% of honeys in the U.S. Consumption of these bacteria almost never affects an older child or adult, but the immature infant intestine seems susceptible to colonization by this bacterium. As the bacteria multiply, it releases a potent toxin, (have you heard of Botox?). This botulism toxin affects the nerve endings in the body, causing paralysis, and can lead to death.
Not only in honey, the botulinum spores are very commonly found in soil as well as in the dust in vacuum cleaner bags. The greatest risk factor for infant botulism is not honey, but living on or near a farm. The chief risk is in the first 6 months of life. Of course, the incidence of botulism in infants is low and most babies exposed to honey or dirt will not developclinical signs of botulism.
Studies suggest that the incidence of botulism may be greater in breastfed babies, although their cases prove to be milder and cases of sudden death from botulism are found chiefly in formula-fed infants. Some small percentage of SIDS is thought to be related to botulism. It is possible that the friendly breastfed infant flora may not compete well with botulinum bacteria, although the rate of growth must be kept in check by breastmilk. The iron in formulas causes a very vulnerable intestinal environment and may be the cause of the more-overwhelming cases in formula-fed or formula-supplemented infants.
Constipation, although a common finding in babies, can be an early symptom of botulism. If a baby develops constipation along with some weakness, such as reduced ability to hold his head up or to suck, these symptoms should be brought to the attention of a doctor.
