The acute toxicity of inorganic tin is manifested as
gastric irritation, nausea, vomiting and abdominal
discomfort. Inorganic tin salts are poorly absorbed
by the gastrointestinal tract and rapidly excreted.
Nevertheless, there are several case reports of
gastric irritation and vomiting in humans consuming
canned foods or beverages, particularly
sour fruit products packaged in tinplate cans and
containing high levels of tin. Food and especially
canned food represent the main source of human
exposure to tin. Maximum level of tin in canned
foods is 200 mg/kg for canned foods other than
beverages and 100 mg/kg for canned beverages,
including fruit and vegetable juices (Commission
Regulation EC No 1881/2006).
