A New Hope food warehouse was infested with rodents, insects and birds in July, according to a warning letter issued this month by the U.S. Food and Drug Administration. The FDA ordered the company, New Wha Ming Trading of MN, Inc. to correct violations within 15 days or explain why it needs more time. During five visits in July, inspectors noticed live and dead rodents, including several dead rodents in traps; droppings in 17 locations on food and elsewhere; nesting material and gnawed containers. Bags of food were stained with urine. There were bird droppings on cans of condensed milk. Insects were found on bags and on a dead rodent. Owner Weizhen Lin said Wednesday he had not received the FDA letter but the company is "working on the issues." Read the FDA's warning letter here.
