New details released in botulism outbreak investigation
25th September 2025
The Food Standards Agency has released an update on the investigation into the botulism outbreak that resulted in the deaths of more than 700 cattle.
The FSA and UKHSA confirmed that the outbreak was linked to animal feed made from bakery waste, which affected three suppliers and five farms. However, sampling is ongoing to confirm this connection.
The UKHSA said that the risk to public health was negligible, as the strain is not believed to spread to humans through the food chain, though the incident has resulted in the deaths of more than 700 cattle.
Jodie Wild, head of the incidents unit at the FSA, said: “There is no indication of impact to human health as we continue to work with partners following an outbreak of botulism in cattle linked to animal feed, linked to bakery waste.
“Testing so far has confirmed the presence of toxin types C and D, which are predominantly associated with disease in animals and birds.
“We recognise the loss of these cattle and its impact on the famers concerned and the wider agricultural industry. The situation is kept under review as information and results are received. If we identify any further concerns, we’ll act quickly to protect both public and animal health and welfare.”
Ms Wild added that “rapid action” was taken by the supplier to remove animal feed from the supply chain, and any affected farms have been notified directly by the feed suppliers concerned and authorities where required.
The Agricultural Industries Confederation (AIC) said it is seeking meetings with the relevant authorities to review the incident and discuss key learnings.
