Burgers, if bought rather than just minced beef and sausages are also both classified as processed meats. There is a big question mark about those.
Though apparently most people in the UK don't actually eat the quantities that the EPIC study, which I think was the most recent study, found to have an association between them, CVD and Cancer
Both burgers and sausages can vary by a huge amount when it comes to how much is actually meat.
But if they are of high meat content there is little difference between them and minced beef, lamb, pork, turkey, etc.
I've always found it interesting how products containing minced poultry or fish tend not to to be called "processed meat". Ever when adulterated with non meat.
When bacon is. Even though it can be easily identified as part of an animal.
Nor is "coated meat", such as battered fish, considered "processed meat".
