Details of Spring & Mulberry chocolate bar recall

Spring & Mulberry issued the recall Monday, Jan. 12. The recall impacts one lot -- lot No. 025255 -- of the company's 2.1-ounce Mint Leaf Date Sweetened Chocolate Bars.

The company said in the recall announcement that there have been no illnesses or adverse health effects reported in connection with the recall.

"Spring & Mulberry is proactively recalling the specific lot in which this risk applies to protect public health," the company stated. "The potential for contamination was noted after routine testing by a third-party laboratory."

Customers who purchased the affected chocolate bar can locate the lot code on the back of the packaging and on the "inner flow wrap," the company said.

Spring & Mulberry urged customers to dispose of any affected product and contact the company via email with a photo of the lot code to request a refund.

What to know about salmonella

Salmonella are bacteria that cause about 1.35 million infections in the U.S. every year, with contaminated food as the source of most of these illnesses, according to the Centers for Disease Control and Prevention.

People can become infected with salmonella after unknowingly swallowing the bacteria, or after touching infected animals, animal feces, and "places animals live and roam," according to the agency.

"Although scientists have identified more than 2,500 Salmonella serotypes (types), fewer than 100 types cause most human illness," the CDC states.

What are the symptoms of salmonella?

People infected with salmonella can experience a range of symptoms including abdominal pain, fever, headache, watery diarrhea that may also have blood or mucus, loss of appetite, nausea, and vomiting, according to the CDC.

Symptoms usually begin six hours to six days after swallowing the bacteria.

Most people recover without treatment after four to seven days, the CDC says. However, they should still drink plenty of fluids and rest well.

Some people, particularly children under the age of 5 and adults 65 and older, or those with weakened immune systems, may experience "more severe illnesses that require medical treatment or hospitalization," the CDC says.
