North Island farmers have been warned to check their stock for signs of facial eczema following a sharp jump in spore numbers from the fungus that causes this disease among livestock. <\/p>\n
The disease is caused by spores from the fungus Pithomyces chartarum, which live in pasture and produce a spore containing a toxin that causes liver and bile-duct damage to livestock when eaten. <\/p>\n
The high spore counts were the result of high soil temperatures and recent wet weather, AsureQuality facial eczema monitoring co-ordinator Leo Cooney said. <\/p>\n
''There is a combination there that is a recipe for disaster.'' <\/p>\n
The most recent report from Gribbles Veterinary Laboratory on April 17 showed counts were at extremely high levels in many districts. <\/p>\n
Most Waikato districts were rated as a high risk. <\/p>\n
The district with the highest levels was the Hauraki Plains, which scored a count of 535,000 spores per gram followed by Waitomo, which scored 205,000 per gram. <\/p>\n
The highest in the North Island was Horowhenua with 762,000 per gram. <\/p>\n
Counts become dangerous to livestock when they measure over 100,000. <\/p>\n
Cooney said the worst cases of facial eczema always followed droughts and these areas were the ones affected the most. <\/p>\n
