Does rinsing in the sink really kill e-coli virus?
No. E-Coli is only killed by high temperature. That's why rare burgers are so dangerous & why restaurants won't serve them. When beef is ground into a burger, the outside of the meat gets into the inside, where the E-Coli will survive if the burger is rare or medium rare. A steak (not ground beef) is OK rare because the E-Coli is only on the outside where the heat kills it.
