Mold growing on my crock pot meat at 60C/158F ?

So I use my sous vide controller to keep my crock pot at the above temperature for 24hrs to make super tasty lamb or beef. Slowly melts the collagen, doesnt overcook.

But often, I end up with MOLD growing on the top part of the meat that was not submerged in the juices! The temp of the interior, lid closed, is kept steady.

Didn't think mold grew at 158' !!??

Actually ot doesn't happen when I use a bag , proper sous vide style. It happens when I simply use my sous vide controller to keep my otherwise normal crock pot at 70C. And it's definitely mold.

This question looked interesting so I did a cursory search. It seems that bacterial contamination is a bigger possibility because I didn't see anything about mold (but didn't look long). Can you remove more of the air from the bag when sealing it? That might help with the mold problem and also aid in keeping the meat at the correct temp while cooking.

Well, temp was held at 70C for 24hrs. The part of the lamb that sat in its juices (and cinammon, black pepper, salt, cloves, coconut shavings, and raisins oh my), was exquisite. I guess, even inside the pot, the meat exposed to air was at a relatively lower temp, low enough for mold. Weird. And disappointing !

Interesting, sorry about your stews. Apparently only about 30 fungi can grow above 45 degrees Celsius. Among those, 60 degrees seems to be the limit: ncbi.nlm.nih.gov/pmc/articles/PMC99000
