What causes the illness?
Infant botulism is caused by the food poisoning bacterium Clostridium botulinum. This is the same bacterium that causes the food poisoning known as "botulism". Spores of these bacteria are ingested by the infant, grow and produce a neurotoxin (i.e. poison) in the infant's intestine.
Spores of C. botulinum may be easily ingested as they are common in soil and dust. This may lead to botulism in children younger than one year. Many infants who develop infant botulism have been fed honey, the only identified food source of C. botulinum spores causing infant botulism. Three of the sixteen infant botulism cases (as of June 1999) reported in Canada since 1979 have been associated with honey.
How common are C. botulinum spores in honey?
C. botulinum spores have been found in honey that was implicated in infant botulism. Random surveys of honey produced in Canada indicate that C. botulinum spores are rare. Spores of C. botulinum are present in less than 5% of honey and are typically found in very low numbers.
How can honey become contaminated with C. botulinum?
It is not known how honey becomes contaminated with C. botulinum. Spores of C. botulinum, which are commonly found in the environment, may be picked up by bees and brought to the hive. Other microorganisms found in the environment around honey (ie. bees, hives, pollen, soil, flowers, etc.) are also likely to occur in honey.
How can infant botulism be prevented?
Honey is the only food implicated in infant botulism. Since it is not essential for the nutrition of infants, parents and caregivers are reminded not to feed honey to infants less than one year of age. Honey should never be added to baby food or used on a soother to quiet a fussy or colicky baby. Concerned parents should discuss alternative methods for quieting their baby with their pediatrician or family doctor.
