So I’m not new to dry aging with the UMAi bags, but I really pulled a rookie move the other day.

Bought 3 whole crypto-vac striplions from my local butcher, brought them home and chucked them in the fridge for a day while I moved my trusty Dry aging fridge to our new house. I’ve used this fridge for a couple dozen slabs and it has worked flawlessly. I added multiple fans, and a large salt basin in the bottom drawer for air movement and moisture extraction. Also have LED lighting and a webcam to monitor the progress. :P

Anyways, had company over, so my attention was not 100% on what I was doing, while I was prepping everything to transfer over into the UMAi bags. Upon sealing the first slab up, I realized I forgot to wash the cryo-vac big prior to transferring the meat into the UMAi bag. Marked the bag, and fixed my mistake with the next 2 slabs. That was Saturday. Last night I opened the fridge and noticed the marked slab had a number of patches of white mould all over both sides, on the fat cap and on the inside the bag. :unsure: :dry:

Now I in a bit of a quandary of what to do with this meat. I have thought about pulling the meat, trimming on multiple cutting boards as not to re-cross-contaminate the meat with the mold, before rebagging it. I also read something about wiping the meat down with apple cider vinegar to sterilize the meat.

The other slabs looked fine last night, will inspect again when I get home.

It seems very strange that patches of mold could have shown up in a 24 hour period!

You sure are right to be in a quandary. Despite your experience and your set up, it sure sounds like you got some contamination going on there. Mold is seldom a good sign on fresh meat, particularly right at the beginning of the process.
“Abandon ship!” Is all I can think to imagine.

UMAi Dry is designed to be used In a modern frost free refrigerator in regular use located within a consistently room temperature environment. Fans and salt can replace the humidity management of the proper compressor.

One further note: from Ulta grow outside that meat so quickly, you should be very concerned about the temperature control in your fridge. It should run between 34 and 38°F consistently. From mold to grow that quickly, guaranteed that fridge is running well over 42°

Fridge temperature sits between 0.8-1.8°C and does not fluctuate.

The fridge is a modern frost-free unit but because I tend to do multiple cuts of meat for different lengths of time, a dedicated fridge was required. The fans and salt are just to ensure circulation and moisture control. The salt barely absorbs any moisture from the fridge
