Meat from a herd of sheep stolen in Cumbria could be harmful to humans if eaten, police have warned.
Heavily-pregnant ewes that had recently been injected with the drug, Trodax, were stolen from a farm in Milnthorpe earlier in the month.
Police said the anti-parasite compound, designed to kill Liver Fluke, can prove extremely harmful if the meat is consumed within 49 days of the jab.
The herd of 10 sheep, worth £1,000, was stolen from Greenmount Farm.
A spokeswoman from Paragon Veterinary Group in Carlisle said it was not known what the effects of the drug were as there was no evidence documented.
Police have appealed to anyone with information, including any person, restaurant or butchers who may be offered lamb from an unknown or suspicious source, to contact them.
