The USDA has rescued five beagles from animal shelters and trained them to sniff out a specific type of contraband in JFK International Airport: meat and produce.

In 2013, the beagles foiled 21 smuggling attempts involving Peruvian potatoes (which are deemed by foodies and Peruvian immigrants to be far superior to U.S.-grown potatoes).
