Why searing a steak kills bacteria while chicken requires a thorough cook
In short: Understanding why rare steak is safe to eat while rare chicken is dangerous comes down to where pathogens hide. This video explains the biological difference between muscle structures and why searing the surface is only effective for certain types of meat.
The safety of rare steak relies on the fact that harmful bacteria typically reside on the surface of the meat. When you sear a steak, the high heat effectively eliminates these surface germs. In contrast, research from the University of Georgia's Center for Food Safety indicates that pathogens in chicken can penetrate deep into the muscle tissue, meaning surface searing is insufficient to make the meat safe.
This distinction also explains why ground beef carries higher risks than whole cuts: the grinding process distributes surface bacteria throughout the entire mixture. Meanwhile, other meats have different safety profiles; for instance, the USDA updated its stance in 2011 to acknowledge that high-quality pork can be safely consumed when cooked to a pink internal temperature.
