200,000 chickens at two poultry farms near Brisbane were exposed to a food mix containing dangerous levels of Nicarbazin. Almost a quarter of the chickens died.
Queensland Health acting chief health officer Linda Selvey said the chemical was not retained in the animals, so they were safe to eat.
She declined to name the two farms affected.
“We believe that the meat is suitable for eating and we are obligated under the Food Safety Act not to reveal such identities,” she said.
“They are absolutely safe. Some of their colleagues have ingested too much of this chemical, they died but those that survived actually recovered pretty quickly.”
