Salmonella outbreak hits 23 states, source unknown: CDC

An outbreak of salmonella is affecting nearly two dozen states, according to federal health officials.

A total of 212 people have been infected with a strain of Salmonella Newport in 23 states. Since the Center for Disease Control and Prevention's (CDC) last update on July 21, 87 new cases have been reported, including 38 from eight new states, Florida, Maine, North Dakota, South Dakota, Virginia, Idaho, Arizona and Nebraska. The CDC said 31 people have been hospitalized but to date, no deaths have been reported.

“This outbreak is rapidly growing in size," the CDC stated in a release Friday, noting that a specific food item, grocery store or restaurant chain has not been identified as the source of infections.

Symptoms of salmonella infection typically begin six hours to six days after being infected and may last up to a week.

"However, some people do not develop symptoms for several weeks after infection and others experience symptoms for several weeks," per the CDC.

Symptoms include:

  • Nausea, vomiting
  • Diarrhea (that can be bloody)
  • Fever
  • Headache
  • Stomach cramps

In rare cases, salmonella infections can be fatal. Those with weakened immune systems, children under 5 years of age, and adults over 65 are more at risk to have severe symptoms.

The CDC asks anyone with symptoms of salmonella infection to report it to their local health department and to keep a record of what foods they ate and where. The information will help public health officials identify the source of the contaminated food and help them stop the spread of this illness.
