Depends on how long it has been growing.

true.
i don't know how long the chilli's must infuse according to the recipes. i'm
guessing it's longer than a week which is enough to get a smelly mess.
i've only come across C. botulinum clinically. i dehydrate my veggies and don't
make my own flavored oils. i do make flavored vinegars (pH too high for bad
things to happen) and preserves (too much sugar to support life other than
fungus, and you can see that)
