BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) are two additives that prevent the oxidation of fatty substances and the alteration of colour and other qualities of the products to which they are added. Those additives can be found in pet food but also in human foods, such as frozen foods, ready-made soups and potato chips, for example.
BHA and BHT are also part of the list of additives authorised in animal nutrition by the European Union, under the maximum limits set for use in pet food. The authorisation of additives is a very rigorous process and is under the supervision of the European Food Safety Authority (EFSA).
At Purina, we strictly comply with the maximum levels permitted by law to ensure our products are completely safe for all pets.
