a fume cupboard can be created or rented, and collections should be vacuumed with a HEPA vacuum and swabbed with isopropanol. Operators should be using PPE. Collections should be returned to a dry climate (RH at 40% +/- 5) onto shelves that have been disinfected.<o:p></o:p></span></p>

<p style="background:white;box-sizing:border-box"><span style="font-size:10.5pt;font-family:Roboto;color:#353C41">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. <o:p></o:p></span></p>

<p style="background:white;box-sizing:border-box"><span style="font-size:10.5pt;font-family:Roboto;color:#353C41">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>
Is ammonia the best way of cleaning specimens? Should we be using Ethanol or another solution for the specimens with visible mold growth? <o:p></o:p></span></p>
<p style="background:white;box-sizing:border-box"><span style="font-size:10.5pt;font-family:Roboto;color:#353C41">How would you wipe down/rid the bird skins of mold growing on them? Damp rag with ethanol? Cotton swabs?<o:p></o:p></span></p>

We put in dehumidifiers this week to try and drop the humidity even further and are considering an anti-fungal fogger. If anyone has had experience with any of these foggers, we'd appreciate your insight. <o:p></o:p></span></p>
