If there's a tiny bit of mold on nearly-finished maple syrup (like, a tiny patch in a pot of 1.5 gal), and it's removed and the syrup is brought back to a boil, is there any particular pathogen that would make it unsafe to bottle? Wikipedia says botulism toxin "is destroyed by heating to more than 85 °C (185 °F) for greater than 5 minutes." But is there any other information I'm missing?
I'm fully expecting a lot of "better safe than sorry" comments. Short answer to that is, "yeah I know."
