Our collection here at the National Fish & Wildlife Forensic Laboratory is experiencing an unprecedented mold outbreak in our bird collection and we could use some advice about mold removal and cleaning while protecting the specimens.</p>

A few weeks ago we found two cabinets with mold growth, some skins were nearly encased in a thin mold film. The specimens with obvious mold growth were moved to the freezer, then cleaned with a cotton swab dipped in ammonia. All other specimens were placed
in a hood with a UV light for 24 hours. The drawers were cleaned with ammonia and then a UV light was placed inside the cabinet for 24 hours. </p>

We have now discovered more cabinets with mold. Has anyone encountered large-scale mold outbreak in their collection? How did you handle cleaning?</p>

>From what I've read, UV light exposure will kill the mold and won't necessarily harm the specimens unless exposed to UV light for an extensive period of time. <br style="box-sizing:border-box">
Is ammonia the best way of cleaning specimens? Should we be using Ethanol or another solution for the specimens with visible mold growth? </p>

This is a brand new facility built in the last year.<span style="color:rgb(53,60,65);font-family:Roboto,"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:14px"> The humidity in the building ranges from 40-42% and the temperature is kept from
