Missouri is one of several states warning residents about an outbreak of infections linked to puppies and affecting humans. Centers for Disease Control, the U.S. Department of Agriculture, and seven states are reporting an outbreak of Campylobacter. It’s a microbiological infection causing inflammatory, sometimes bloody diarrhea, cramps, fever, pain, or dysentery syndrome. The outbreak has been linked to puppies sold at Petland stores. You could be affected if you recently bought a dog there, visited one of their stores, or were in a home of someone who recently visited or bought a dog from Petland. The illness has been identified in Missouri, Florida, Kansas, Ohio, Pennsylvania, Tennessee, and Wisconsin.
