Recent reports filed by the United States Centers for Disease Control and Prevention gave new information about the massive Salmonella infections outbreak spread in 19 states all across the US starting with 2006.

Apparently, the incident was linked to tainted dog food which is the source of the outbreak. A large number of dry pet food brands were investigated in order to determine which of those was dangerous and two brands were recalled off the market in order to put an end to the disease spread.

"This is the first time human illness has been linked to dry dog food," said CDC epidemiologist Dr. Casey Barton Behravesh, who co-authored a report on the finding, according to the Washington Post.

The most affected area by the disease was Pennsylvania with 29 cases, New York followed with 9 cases and Ohio with 7. About 40 percent of the infected people were infants.

The disease produced by the Salmonella bacteria is called salmonellosis and for most of the infected people is known to cause diarrhea, feverand abdominal cramps. The illness generally lasts four to seven days and people normally choose to tough it out without a treatment.

The CDC strongly recomands that all animal owners should always wash their hands after touching pet food. Also, other recomandations refered to the pet feeding areas where children should not be allowed and infants under 5 should not touch or eat pet food, treats or supplements.
