Pretty sure you mean water bath canning for something like chili, and that's actually not safe unless it's pressure canned. Chili has meat and low acid stuff like beans and tomatoes, so botulism is a real risk with just a hot water bath. A pressure canner gets to 240F which is what kills those spores, water bath only hits 212F and that's not enough. Not trying to rain on your parade because 30 jars is a lot of work, but if those weren't pressure canned you might want to look into it before eating them. Better safe than sorry with home canned meat stuff.
