South Africa's RCL Foods said on Thursday its poultry unit Rainbow has culled 410,000 chickens due to the country's worst outbreak of avian flu, heightening fears of chicken meat and egg shortages.

Last week, RCL's peers, including the country's largest integrated poultry processor Astral Foods and Quantum Foods, said the bird flu outbreak was ravaging a sector that was already burdened by South Africa's electricity crisis and rising costs.
