Meat glue, also called transglutaminase (nothing to do with so-called pink slime), binds together bits of meat into what looks like a prime cut. But: When not handled properly, meat glue can seal in E. coli and other bacteria present on raw meat. Self-defense: Check package labels—glued meats must include the words “formed” or “reformed.” Glued meats are commonly used in high-volume restaurants and banquet facilities. To be safe, eat meat cooked well-done.
