Police have warned meat producers to carry out checks on livestock after 16 lambs were stolen from a farm near Dungannon, Co Tyrone.
The lambs were taken from a farm on the Eglish Road at around 8.30pm on Saturday.
Chief Inspector Graham Dodds said: “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.
"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."
Anyone with any information about the theft is asked to contact Dungannon police station on the non emergency number 101.
