I stored two wet supers over the winter - because of varroa treatment I didn't get the chance to put them on the hive for cleaning up. Some of the frames had a lot of pollen in. (Came from a hive where I'd done a Snelgrove split). The pollen does not seem to be mouldy - it has been in a cold shed all winter. Will it be ok to put it back on a hive as it is?
