None of the PVC melted, it just deformed and it was only in there for like 7 seconds before I got it out. Did I ruin/poison/contaminate my batch?

I was able to find this about someone dropping a probe with a PVC handle into their boil:

"A study published in the Journal of Applied Polymer Science shows high rates of leaching of plasticizers in PVC at high temperatures. PVC powder alone appears to be fairly inert, according to Ullmann's Encyclopedia of Industrial Chemistry, but Vinyl chloride monomer (VCM) is highly carcinogenic and is an upstream product in the manufacturing of PVC.

Does your thermometer carry an NSF logo? NSF logos indicate the device has passed certain safety tests for use in a food service environment.

I know it is really difficult to throw out a batch of beer; it may be fine to drink, too. The way I would approach this issue is by considering the incremental impact of routinely being concerned about what you're ingesting (i.e. a few dozen cigarettes never killed anyone, but a lifetime of smoking does kill). If it were mine, I'd probably keep the beer and be as cautious as possible down the road."

No, your fine. Even using it under normal conditions, it sits above boiling wort and steam and condensation collects and drips back to your wort. No way of getting around that and I've never had I'll effects or off flavors due to it.

Thanks guys, I was fairly concerned, but screw it. I'm making this mint chocolate porter if it kills me

...which it hopefully won't!

7 seconds should reallty not be liong enough time to leach a problematic amount from the PVC. I agree just be careful in the future.

If you are worried about the potential of this happenning again, you can get the 5 gal paint strainer bags and use a binder clip to hold it to the side. I do this and it works like a champ. Never had any scorch issues being on the side. Almost as easy to use as a spider too.
