Can you get botulism from canned tomatoes?
Botulism is a concern with all canned goods, and tomatoes are no exception. Although the bacteria don’t thrive in acidic environments, cases of botulism have cropped up in canned tomatoes. Avoid cans that are dented, leaky, rusted or swollen, and discard those that are foamy, cloudy or foul-smelling upon opening.

Do home canned tomatoes go bad?
High acid foods such as tomatoes and other fruit will keep their best quality up to 18 months; low acid foods such as meat and vegetables, 2 to 5 years. If cans are in good condition (no dents, swelling, or rust) and have been stored in a cool, clean, dry place they are safe indefinitely.
Why did my canned corn turn brown?
Corn often turns brown during processing as a result of caramelization of sugar. The sweeter the corn at the time it is canned, the more likely it is to turn brown. The long processing time required for corn packed in quart jars also tends to darken it. Processing corn in pint jars might prevent darkening.
