Sometimes you are in a rush and you just want to grab something quick to eat but maybe you should have a second thought on what you will get.

Consumer groups-U.S. Public Interest Research Group Education Fund, Natural Resources Defense Council, Consumer Reports and more, put together a list of the most popular fast food restaurants and what antibiotics they use in their beef.

According to the list, Chipotle was the best with an A grade, McDonald's and Subway with a C, Wendy's with a C- and Taco Bell with a D. The interesting bit about this report is how many restaurants got a failing grade for their beef.

The restaurants with failing grades includes Panda Express, Starbucks, Burger King, Domino's, Pizza Hut, Applebee's, Arby's, Little Caesar's, Dairy Queen, Buffalo Wild Wings, and Olive Garden.

That's a lot of restaurants.

The reason for this is that the antibiotics is causing a bacteria develop in food products and get them very sick.

Some fast food companies like Chipotle and McDonald's have strict policies on antibiotics and have made huge strides.
