The Food and Drug Administration has ruled that ranchers and farmers need to restrict some of the antibiotics they give their livestock.

The FDA is specifically limiting the use of cephalosporins, a type of antibiotic that's often given to cattle, pigs, and poultry.

These drugs are used in people to treat pneumonia, skin infections and meningitis, among other diseases.

The concern is that over time, people who eat meat that contains this antibiotic will develop an immunity to the potentially life-saving medicine.

"We are ruining these antibiotics for human use because we are using it on animals that are not sick," said Mike Callicrate, the owner of Ranch Foods Direct in Colorado Springs.

Ranch Foods Direct only sells meat and dairy products that are natural and antibiotic-free.

"If you want a healthy body and healthy family, you have to feed them good food," said Callicrate.

Callicrate thinks the FDA needs to take more drastic measures to protect consumers.

Julie Meyer agrees. She doesn't mind spending extra money on her groceries to make sure all of the meat she buys is natural.

"You can either spend your money on your food, or you can spend it on going to the doctor and spending it on medication. I'd rather spend it on healthy food," said Meyer.

But not everyone is concerned about the use of antibiotics in livestock.

"I know it's been tested and deemed safe for us, so I would say no, I don't worry about it," said Steven Harvey.

Opponents of the FDA's ruling say there is not enough evidence to prove that antibiotic use is actually unsafe.

The FDA first proposed similar restrictions back in 2008, but ended up pulling them because of backlash from ranchers and farmers.
