New Salmonella Outbreak Could Be Caused By Pig Ear Dog Treats, CDC Says

The salmonella infections are linked to pig ear dog treats.

The FDA says people are handling the treats, then eating or preparing food without washing their hands first.

The pathogen also spreads through feces.

People can become sick just by petting their dogs or their dog tracking feces through their homes in their paws.
