Fog fever is a misnomer, since neither is it caused by fog, nor do sufferers have a high temperature. The scientific name is Acute Bovine Pulmonary Edema (ABPE). The condition occurs in hungry, typically adult cattle, having been fed on dried feed indoors, and then moved to foggage pasture (fast growing, lush pasture, with high protein levels). The cattle graze on the new feed, clinical signs begin within 1 – 14 days and death often follows within 2 to 4 days after the appearance of clinical signs. The condition can affect up to 50% of the herd, and around 30% of affected cattle may die as a result. A similar condition has been reported on a wide variety of grasses, alfalfa, rape, kale, and turnip tops.
