In small ruminants, botulism is more common in sheep than in goats. Typically, no significant changes are observed post mortembut the botulismmo of bones in the rumen and reticulum may indicate botulism due to osteophagia.

Other botuilsmo toxin sources for cattle, which have also been reported for buffaloes, are stagnant water sources, such as swales, rain water harvesting ditches and small lagoons SILVA et al.
