With the severe weather that the North East has been having here is a tip you should be aware of. The waste drainage system in you home and business may have a vent system that extends a foot or two above the roof line. It is most probably, one or more pipes---1 1/2 to 2" diameter. If these pipes are closed off because of ice and snow, the traps may have the standing water in them vacuumed out, allowing sewer gases to enter your home. Remember---all smells are particulate-----so if you smell even the slightest stink----check those vents!! I can't imagine a worst case scenario for a cheese maker.
Be aware this can happen in warm weather also----birds and bees can build nests that can block these pipes.
