Hill’s Pet Nutrition has issued a further recall of cat food owing to a risk of illness in pets.

The company's cat food pouches have been found to contain high levels of iron. If fed as the sole source of nutrition, this may have a more serious health effect, including diarrhoea and vomiting.

Hills say that the high levels of iron present in the pet food were as a result of an error by an ingredient supplier, which resulted in 85g pouches being manufactured incorporating high levels of iron, some of which were packed into multipacks with unaffected products.

Following additional product testing, an additional product, Science Plan Feline 11+ Healthy Ageing Chicken & with Salmon Multi Pack, was found to have higher iron levels than declared on the packaging. The 12 item, 85g multipack has a SKU code of 2190V and expiry date September 2017

A company statement said: “The company say that this is a precautionary measure as although iron is an essential nutrient in a cat’s diet but too much iron may cause digestive upset.”

On the product recall it states: "The company recalled certain packs of cat food pouches in May 2016 because there were high levels of iron present in the pet food as a result of an error by an ingredient supplier, which resulted in 85g pouches being manufactured incorporating high levels of iron, some of which were packed into multipacks with unaffected products."
