Affco New Zealand is in the firing line after a Whanganui employee allegedly became seriously ill after cleaning up spilled offal.
Brian Wright was working in the rendering department at Affco's Imlay meat processing plant in Whanganui in June 2015 when he cleaned up the offal.
Wright became seriously ill and required surgery to replace a heart valve.
WorkSafe New Zealand has filed a case against the meat company for a breach of health and safety regulations.
It says Affco failed to take all practicable steps to ensure Wright was not exposed to hazards arising out of work with raw materials in the rendering plant. The prosecution is under the Health and Safety in Employment Act.
