Incidence of suspect botulism in the UK has increased substantially since 2003.
Evidence suggests that direct access to litter from broiler houses is a significant factor in most of the recent outbreaks of suspected and confirmed botulism in cattle and sheep. Litter stored or spread on neighbouring farms may also be a factor.
The
VLA guidelines for farmers aim to control these risks. Advice includes not using litter on ruminant farms wherever possible and adopting good personal hygiene when moving or spreading litter.
