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.
