In the
European Union, pet food is regulated by the same harmonized standards across the EU, via the
Feeding Stuffs Act.
[20]
All ingredients used for pet food has to be
fit for human consumption according to EU requirements. But regulations require that pet food that contains by-products be labeled as "Not for human consumption" even though such by-products have to be derived from animals declared fit for human consumption.
Raw pet food has to be labeled "Pet food only".
[21]
Products meant for daily feeding are labeled "Complete feedingstuff" or "complete petfood" or other
EU languages equivalent. Products meant for intermittent feeding are labeled "Complementary feedingstuff or "complementary petfood" while products with an ash content of over 40% are labeled "Mineral Feedingstuff". Ingredients are listed in descending order by weight.
