A man has been arrested by police investigating how dog poo came to be listed on the ingredients of a packet of sliced ham.
Detectives were called after reports that the words were found on the label of a 300g packet of the cooked meat, bought in Wakefield, West Yorkshire.
Meat manufacturer HR Hargreaves & Son, from Salford, Greater Manchester, is recalling the products.
A 21-year-old man was arrested on suspicion of tampering with the label.
A spokesman for Greater Manchester Police said: "A 21-year-old man from Salford, Greater Manchester, was arrested on suspicion of making claims to have made goods appear contaminated."
The man was bailed by police as detectives continued to investigate.
