Is It Bad To Defrost Meat Under Hot Water. In 2011, the department of agriculture conducted a study, and they found that warm water and hot water thawing methods for meat was safe. Hot water in particular is a pretty bad idea.

Prompt cooking might well eliminate that problem, but until this has been studied, it’s safest to continue thawing roasts in the refrigerator or in water under 40 degrees. However, as soon as they begin to thaw and become warmer than 40 °f, bacteria that may have been present before freezing can begin to multiply. And as you run it under hot water, it’ll start to cook the exterior of the meat while it’s still frozen solid inside.
