Cases of emesis associated with bacterial contamination of an infant breakfast cereal product.
A commercial product for infants containing cereal mixed with dried infant formula was diagnosed as producing rapid projectile vomiting in two infants. Analysis of multiple samples of the cereal product revealed significant contamination with two spore-forming species, Bacillus subtilis and a strain of Bacillus cereus. The latter is the most likely cause of the emetic food poisoning, but we were unable to detect B. cereus emetic toxin. This raises the possibility of the cause being either a new cereulide-type toxin, or the bacterial load, in which case the presence of B. subtilis could have been a contributing factor.
