The European Food Safety Authority (EFSA) has called for additional research into the presence of a potentially toxic insecticide in meat and vegetables and all animal feeding stuffs.

After an investigation, EFSA has concluded that while there is wide knowledge that possibly harmful levels of camphechlor are present in fish and fish oil (for human and livestock consumption), it fears “substantial data gaps” regarding its presence in other foods.

It added there was “a general lack of congener specific toxicity data as well as data on oral toxicity for farmed fish”. Camphechlor was heavily used in the 1970s, but has now been phased out in most countries on environmental grounds.
