The owner of Ohio's largest egg producer says he is giving up his environmental fight against the state and retiring to his native Germany. Anton Pohlmann and his Buckeye Egg Farm were in court last week facing the ninth round of contempt charges filed by the state for violating environmental laws. Pohlman told the Newark Advocate that state officials do not appreciate the progress his company has made. Bill Glass, the farm's chief operating officer, says Pohlman left friday for Europe. Pohlmann says he still will come to Ohio occasionally for business. The state has tried for years to get Buckeye Egg to comply with Ohio's environmental laws. The farm's neighbors in Hardin, Licking and Wyandot counties have complained about insect infestations, foul odors and creeks polluted with chicken manure.
