[Botulism in an infant]

We describe a case of botulism in a 4.5 month-old girl with complete recovery after intravenous administration of botulism immune globulin. The girl was admitted for 19 days during which supplementary nasogastric feeding was necessary. Mechanical ventilation was not needed. Despite thorough investigation, contaminated food was not found. One particular batch of canned baby food was suspected and recalled from the market, but no contamination was found. The girl had not ingested honey. The condition is rare, but can be very serious and should be kept in mind in cases presenting with the well-defined symptoms of the condition.

Denmark: botulism in an infant or infant botulism?

A 4.5 months old, previously healthy Danish girl was admitted to a paediatric department after six days of passive behaviour and weak suck. Over the next days she became increasingly weak, developed bilateral ptosis, the muscle stretch reflexes were lost, and mydriasis with slow pupillary responses was noted. Botulism was suspected and confirmed by testing of patient serum in a bioassay. The condition of the patient improved following administration of botulism antiserum. The clinical picture was suggestive of intestinal (infant) botulism. However, botulism acquired from consumption of food with preformed neurotoxin could not be excluded.

The clinical picture was suggestive of intestinal (infant) botulism. However, botulism acquired from consumption of food with preformed neurotoxin could not be excluded. The food history revealed consumption of a commercially produced banana/peach puree which was suspected as a possible source, and based on a precautionary principle this product was recalled. The case description illustrates a risk-management dilemma between suspected foodborne versus intestinal botulism. Taking the potentially very serious consequences of foodborne botulism into consideration, the measures taken were justified.
