 They believe COOL is a thinly disguised trade barrier intended to increase importers' costs and to foster the unfounded perception that imports may be inherently less safe (or of lower quality) than US products.Food safety problems can as likely originate in domestic supplies as in imports, as evidenced by the more than 30 recalls of US meat and poultry products announced by USDA in 2006 alone, these opponents point out.Opponents argue that all food imports already must meet equivalent US safety standards, which are enforced by US officials at the border and overseas; scientific principles, not geography, must be the arbiter of safety.
