Yes, foodservice does use them, for non reactive foods. Places that care about what they put out will not use them for said foods, not out of health concerns but rather because it impacts the final product by discoloring and/or adding an off-putting flavor to the food.

Swanky's link says the LD50 (average lethal dose) of aluminum is 500 grams or about half a pound. Google tells me the LD50 for copper is about 10 pounds and the LD50 for nickel is about 20 times that. The ironic thing is that we are worried about the toxicity of the cups when we are filling them with alcohol, a substance known to be much more toxic than any of these metals :lol: :wink:

You shut your whore mouth about alcohol! :D
