We examine the impact of mergers on product quality in the U.S. agri-food industry. Our difference-in-differences analyses provide evidence that following a one standard deviation increase in merger activity there is a 48.1% decrease in pounds of food recalled and an 18.7% decrease in the total number of recalls. A significant implication of our analysis is that increased concentration increases product quality.
