How old are the cows used for beef in your burgers?

The age requirement for beef animals entering McDonald's supply chain is a minimum of eight months, the age of beef animals at slaughter varies greatly as there are many options available to farmers in rearing cattle. McDonald's do not accept beef animals into their supply chain younger than eight months as these are classed as veal; all animals entering the McDonald's supply chain must meet our specifications on traceability, animal health and welfare, and the origin of where the animal is reared.
