That bacon at breakfast. The ham in your sandwich. The pepperoni on your pizza. The hot dog at the ballgame. These everyday foods are delicious, convenient, and deeply embedded in our food culture. But they also come with a cost that many people don't fully understand.
Processed meats have been classified by the World Health Organization's International Agency for Research on Cancer (IARC) as Group 1 carcinogens—meaning there is sufficient evidence that they cause cancer in humans. This puts them in the same category as tobacco and asbestos.
But what does that actually mean for your health? Let's explore the evidence.
What Counts as Processed Meat?
Processed meat is any meat that has been transformed through salting, curing, fermentation, smoking, or other processes to enhance flavor or preserve it.
Common examples:
-
Bacon
-
Sausages (including breakfast sausage, bratwurst, chorizo)
-
Hot dogs and frankfurters
-
Ham
-
Salami, pepperoni, and other cured meats
Health -
Corned beef
-
Pastrami
-
Jerky
-
Luncheon meats (bologna, turkey slices, roast beef slices)
What doesn't count: Fresh, unprocessed meat (steak, pork chops, ground beef from fresh meat, fresh chicken) is not classified the same way, though red meat has its own separate classification (Group 2A - probably carcinogenic).
