Development of transgenic horticultural crops has slowed significantly in recent years for several reasons, including the European Union's moratorium on biotech approvals, lack of tolerance levels for adventitious (accidental) presence in food and seed, significantly increased regulatory costs and decreased acceptance by food wholesalers and retailers. While progress in the United States has slowed and approvals in the European Union stopped, some countries such as China continue to develop biotech products for their internal and external markets that will affect the U.S. and California industry. Within a few years, China will emerge as the leader in biotech horticultural crops.
