Why are food recalls on the rise?

A growing number of people are concerned about food safety after a series of recalls over food contamination. Pepperidge Farm voluntarily recalled more than three million packages of Goldfish crackers Tuesday over possible salmonella contamination. Mondelez International also issued a voluntary recall of 16 varieties of its Ritz cracker products because of the same concerns over salmonella. Michael Moss, an investigative journalist who won a Pulitzer Prize for reporting on contaminated food, joins “CBS This Morning” to discuss why food companies should be more diligent and what might be behind the rise in recalls.
