U.S. Customs and Border Protection agriculture specialists inspect flowers for any foreign pests or diseases at the UPS facility at Miami International Airport on Friday. As Valentine's Day approaches, the airport will see about 85 percent of all flowers imported into the United States. Most of the flowers come from South American growers.
