Wisconsin warns against a holiday tradition: Raw meat sandwiches

Like rules, some holiday traditions were made to be broken. So say health officials in Wisconsin, where it's long been customary in some families to serve at festive gatherings an appetizer of raw, lean ground beef on rye cocktail bread with sliced onions, salt and pepper.

As delicious as that may — or may not — sound, the Wisconsin Department of Health Services recently took to social media to issue its annual reminder that eating what some refer to as a "cannibal sandwich" is not the soundest of ideas. 

That's because "eating them poses a threat for salmonella, E. coli 0157:H7, campylobacter and listeria bacteria that can make you sick," the agency stated in its yearly plea.
