(b) Manure packs in loafing areas, stables without stanchions, pen stables, resting barns, wandering sheds and free-stall housing are properly bedded and managed to prevent fly breeding.

(c) Milkrooms are free of insects and rodents.

(d) Milkrooms are effectively screened or otherwise protected against the entrance of vermin.

(e) Outer milkhouse doors are tight and self-closing. Screen doors shall open outward.
