Causes of mold on a rind washed soft cheese?

Hello,
Hope everyone is having a super day. My question is this. We make a washed rind semi- soft cheese which is aged in a cooler for a week. It is washed twice with a B. Linen mixture. A mold appears on the surface of the rind at about a two week time period. The mold is about a pin point black to dark grey mold and is easily scraped off. Does anyone have any idea where it might be coming from? The cheese is stored on trays on a rolling cart in the cooler. The cheese is covered in a 2 ply cheese paper and then a plastic bag covers that. Thank you so much for your input.

Perhaps the moisture/humidity in the cooler is too high? Is the cooler properly cleaned out regularly?

Have you tested the mould to find out what it is and swabbed the environment? I know trolley wheels are a great place for micro to happily bimble away untroubled by being cleaned (ie have you washed the wheels on the cart recently?)

Dear GMO,

"bimble" ?

From the babies' urban dictionary perhaps.

Thanks to both of you for your replies. I do swab the cooler and the carts regularly for Listeria, but that is it. The carts are washed regularly as well. I will send the mold in to be tested. No one else makes this cheese except our company so the acceptable temperature and humidity ranges are kind of unknown but I am going to start monitoring them both. Thank you very much!
