Peppers and garlic have been used for centuries as a preservative (as has salt). I've stored garlic in a ceramic garlic storer for a long time, and braids of garlic hang for a long time. So while I appreciate the warning, I really don't think it is likely to get botulism from garlic infused oil, I think your chances of getting struck by a car or lightning, or even choking on a piece of garlic or a pepper-seed is a much more likely scenario. :)
