The U.S. biotechnology industry is bracing for a renewed campaign by consumer activists next year to restrict the movement toward genetically modified foods, the U.S. Food and Drug Law Institute reported yesterday. Biotech leaders anticipate the pressure could begin when Congress reconvenes in January and could extend to the U.S. Food and Drug Administration. The issue in Congress will be whether to require labelling of bioengineered foods, while the FDA will be asked to give greater scrutiny to gene-altered food. The FDA is expected to introduce new guidelines on genetically modified foods as early as next month. The new guidelines require producers to notify the FDA at least four months in advance of plans to put any bioengineered food on supermarket shelves. Current FDA policies, developed in 1992, require producers only to consult with the FDA when they are introducing a genetically modified product.
