Fast-Food Farms

Farms often give animals antibiotics to prevent disease and help them grow faster, but scientists worry overuse could make bacteria more resistant to antibiotics, especially for humans who eat the meat. A new report, backed in part by Consumers Union, grades how well major U.S. fast-food chains police this practice. A sampling:

A

(bans routine use of antibiotics)

PANERA

CHIPOTLE

B

(will ban routine use in near future)

CHICK-FIL-A

C

(bans routine use in some cases)

DUNKIN’ DONUTS

MCDONALD’S

F

(zero or undisclosed bans)

STARBUCKS

BURGER KING

WENDY’S

TACO BELL

PIZZA HUT

KFC

DOMINO’S

SONIC

LITTLE CAESARS

DAIRY QUEEN
