Whilst there are other sources of tin exposure in humans, the most common route is via ingestion of inorganic tin from canned foods. 28. This code of practice relates solely to the migration of inorganic tin into foods from the internally plain (i.e. not lacquered) tin coating of tinplate cans. 29. This code of practice is not intended to apply to tin exposure from any other source and is specific to inorganic tin. 30. This code of practice relates to thermally processed canned human foods (including fruit and vegetable juices) which are packed into plain tinplate cans. It is considered that this description covers both: (i) Hot fill and hold products; and, (ii) Hot or cold fill and retort products. Dry goods and 100% oil products are not included, because they do not experience tin migration.
