Police are warning about the theft of 16 lambs which would be poisonous if sold off as meat.
The livestock was stolen from a farm on the Eglish Road area of Dungannon, Co Tyrone, some time before 8:30pm last night.
PSNI Chief Inspector Graham Dodds has warned abattoirs to be careful about accepting lambs in the coming week.
"The farmer who owned these lambs has informed us that they would not be ready to enter the food chain for the next six weeks and that their meat would be poisonous to humans if eaten," he said.
"I would therefore ask any abattoirs to be aware of this and carry out the proper checks on any lambs that they come into contact with in the next few weeks."
The PSNI has appealed for anyone with information about the theft to get in contact.
