What can feeding GM foods to animals tell us about toxicity?

Next Wednesday (15th January) we are all invited to take part in an online Q&A on ‘How useful are animal feeding studies in plant research?’

The Q&A is a chance for people to ask any questions about whether feeding studies are a sensible precaution to determine whether our food is safe, or a misleading waste of money.  Continue reading
