Undercover footage that appears to show extremely sick cows being smuggled into a Polish slaughterhouse is raising alarms about standards in one of the EU’s largest meat exporters.

Covert footage in a slaughterhouse in the central Polish region of Mazovia appears to show cows so sick that they are unable to stand up being dragged out of trucks, and sold on with little or no veterinary inspection.

Chris Elliott, professor of food safety at Queen’s University in Belfast says if there is any evidence at all that some of this meat has left Poland, there will be the potential for a European-wide safety alert.
