As of next month, the USDA will require all food marketed as 'organic' to be certified in accordance with governmental guidelines. Inspectors will check that the product's ingredients are at least 95% free of chemicals. The new guidelines will enhance the credibility of the organic food sector, which is currently open to abuse by producers who do not stick to generally agreed standards. Large players in the organic sector, such as Horizon Organic, have welcomed the implementation of the standards.
