AsureQuality Contributors: Hastings, Dannevirke, Gisborne, Morrinsville, Kaikohe, Masterton, Auckland, Pukekohe/Franklin, Taupo About Facial Eczema Facial eczema (FE) affects most ruminants but especially cattle and sheep throughout most North Island regions plus the northern end of the South Island. FE is responsible for serious production losses estimated to be around $200m annually with affected stock suffering liver and skin damage, which together contribute to ill-thrift, reduced fertility , reduced milk and meat production and, if left unprotected, in worst cases death. During summer and autumn months warm, humid conditions together with dead litter in pasture support the growth of a fungus (Pithomyces chartarum ) in pasture. .Animals graze toxic pasture and once in the rumen the spores release a mycotoxin sporidesmin, which then enters the blood stream eventually finding its way into the liver. The toxin specifically attacks the cells of the bile duct resulting in the liver being unable to process and excrete waste products and phylloerythrin, a chlorophyll breakdown product. Infected animals display signs of photosensitisation and look distressed. The first signs are often reddening and swelling of skin exposed to the sun (i.e. around the eyes, ears, lips and nose) as well as restlessness, shaking and rubbing of the head and ears, and seeking shade. Prevention of Facial Eczema With careful planning and implementing a sound FE management plan, farmers can take control of the risk of facial eczema. Prevention is the only recognised method of avoiding FE. Ensure all staff are aware of the associated risks and dangers of FE but ensure the plan is implemented when spore counts are rising but before clinical signs are identified. Essential to start FE control early. Ideally start prevention with zinc treatment and Fungicidal sprays, two or three weeks before the spore growth danger period for maximum protection. Some of the AsureQuality areas are unavailable due to unforeseen circumstances. If your area has had rain, be extra vigilant with treatment.
