Botulism is a rare but severe paralytic illness caused by neurotoxins produced by Clostridium botulinum bacteria. These toxins attack the body's nerves, leading to muscle weakness and paralysis. It can affect people of all ages, typically through contaminated food, wounds, or in infants.

Botulism was first linked to food poisoning, particularly sausages (hence its name from Latin 'botulus'). The causative bacterium, *Clostridium botulinum*, was discovered in 1895 by Emile van Ermengem following an outbreak. Its historical significance lies in identifying a potent neurotoxin and its role in food safety and preservation.
Botulism is not transmitted person-to-person. The primary routes include **foodborne botulism** (ingestion of pre-formed toxin in improperly processed or preserved foods, especially home-canned items), **wound botulism** (spores entering a wound and producing toxin), and **infant botulism** (ingestion of spores that germinate and produce toxin in the infant's gut, often from honey or soil).

An unprecedented outbreak of infant botulism linked to ByHeart powdered infant formula resulted in 48 cases across 18 states from August to December 2025, representing the first documented foodborne outbreak of this disease in US history. Laboratory investigations confirmed Clostridium botulinum type A contamination. The contaminated formula was distributed online and nationwide (including Guam and Puerto Rico) and internationally to 21 countries, demonstrating the extensive reach of modern distribution networks and the risk of rapid, widespread exposure from a single contaminated product. This is the first confirmed outbreak of this illness associated with powdered formula in US history. All affected infants were hospitalized and treated with BabyBIG. No deaths have been reported.
