We are a honey manufacturer under SQF. In the recent ambient air testing, I noticed the count in hot room (place to melt honey) was as high as 100+ yeast and mold, and 50+ HPC. The plates were put on ground level, where it was dark and humid.
As a corrective action, I did another 5 tests at 5 locations in the hot room. This time the plates were put on honey tank edges (around 1 meter height), right under the ventilation fan. The results came back perfectly at 0 or 1 total count.
I will dig into more research to find a proper air testing procedure in hot and dark environment. Maybe do a another comparison test at the same time. But can anyone share their opinions on this? Do you think the location/height is the reason for such difference??
