The Organic Consumers Association reports the International Journal of Biological Science published a new study this week pointing out serious health hazards from genetically engineered foods and pesticides.
Eight international researchers from France, Italy, New Zealand, the U.K.. and U.S. brought to light a significant underestimation of the initial signs of diseases like cancer and diseases of the hormonal, immune, nervous and reproductive systems, among others.
The study calls into question the reliability of tests of the European Food Safety (EFSA) and the US FDA to assess the health risks of GMOs and pesticides.
It’s crucial to study potential mid and long-term toxicological effects and not test only for short-term or subchronic effects.
It’s essential to complete these tests during the regulatory period, prior to the commercialization of chemicals.
Scientists corroborated the decade-long criticism by public interest organizations such as the Organic Consumers Association, Greenpeace and Friends of the Earth, that unreliable tests have been used to assess the safety of food and products containing genetically modified organisms (GMOs).
Some contaminations or pollutions by pesticides and other chemical 
residues affect human and animal health, while threatening biodiversity. This question has also been raised for GMOs because they can contain pesticides (Roundup Ready soya), or because they produce these molecules (Bt maize).
GMOs are now found in more than 80% of (non-organic) foods sold in conventional grocery stores in the U.S., as well as the majority of animal feed in the EU.
