I was watching a video of Kitchen Nightmares where Gordon found the cooks defrosting chicken in a plastic bag in/on their steam table. He goes on to say that frozen food needs to be defrosted naturally, and that their method is a potentially lethal mistake.
I do not understand how a steam table can be used like; my best guess is that it was a metal tub full of water that they placed the bag into to defrost from the hot steam. Although I don't think that it's a good idea to apply heat to any kind of food while it's in a plastic bag, especially one that was never intended for this particular use case.
However, it makes sense to me that applying a gentle heat like that found in warm water (heated by the steam table) would be one way to defrost frozen chicken quicker. Whether or not this is a good idea from a taste perspective is another matter. But what I don't understand is why Gordon says that this is lethal. At what point between frozen, rapid thawing, and cooking, does the meat become dangerous to serve? This does not seem to be long enough for bacteria to take hold and to become a problem.
