Can soaking flatware in a tin can cause metal poisoning?
Soaking flatware in a tin can will not cause metal poisoning. The amount of tin ingested from tin cans is very small–and tends to occur when an acidic content corrodes the tin. Most cans today are coated with a plastic to further diminish the tin exposure. Still, until World War II, tin was used in such things as toothpaste tubes, and to wrap cigarettes, sweets, and chewing gum.Source:International Programme on Chemical Safety: Tin (World Health Organization Food Additives Series)Dept.
