Publix Super Markets may receive high marks for customer satisfaction, but when it comes to reducing food waste, the Lakeland chain gets a "D" grade. A new study by the Center for Biological Diversity ranked major U.S. supermarkets based on their accountability in food waste, prevention efforts and recovery and recycling. Publix ranked No. 9 out of 10.

"Supermarkets have an enormous influence on the food system," the study said. "Unfortunately, U.S. grocers focus on donating and recycling food waste, rather than preventing it — and they're not even tracking food waste throughout their entire operations."

Publix received 11 out of 50 possible points. The only chain ranked lower was Aldi U.S. Walmart held the top spot with a B grade and 32 points, followed by Ahold Delhaize U.S. with a C grade and 26 points and Kroger with a C grade and 24 points.
