HARARE (Reuters) - Zimbabwe has imposed an indefinite ban on poultry products from South Africa after the country announced an outbreak of highly contagious H5N8 bird flu, the state-owned Herald newspaper reported on Tuesday. "The products include hatching eggs, table eggs, frozen chicken and mechanically deboned meat," Josphat Nyika, the director of the department of veterinary services, told the newspaper. On June 2, Zimbabwe also reported an outbreak of bird flu at a commercial poultry farm near Harare.
