What is Infant Botulism?

Infant botulism is a rare but serious condition caused by the ingestion of Clostridium botulinum spores, which can grow in the intestines of infants (typically those under one year old) and produce a potent toxin. This condition usually occurs when infants consume contaminated foods, particularly honey, which is known to harbor spores.

As of November 10, 2025, this outbreak includes 15 infants with suspected or confirmed infant botulism from 12 states – Arizona 1, California 2, Illinois 2, Kentucky 1, Minnesota 1, North Carolina 1, New Jersey 1, Oregon 1, Pennsylvania 1, Rhode Island 1, Texas 2, Washington 1.

Laboratory confirmation for some cases is ongoing. For

The primary difference between infant and adult botulism lies in the cause and mechanism of infection: adults typically get botulism from ingesting the pre-formed Clostridium botulinum toxin in contaminated food, while infants get sick from ingesting the bacterial spores, which then grow and produce the toxin inside their immature digestive tracts.
