Wegmans Food Markets is recalling 5,000 pounds of Turkish pine nuts because of an outbreak of salmonella that has sickened 42 people in six states, according to the U.S. Centers for Disease Control and Prevention.

The pine nuts were sold in the bulk foods sections of Wegmans stores in New York, Pennsylvania, New Jersey, Virginia, and Maryland between July 1 and October 18, 2011. The nuts were imported by Sunrise Commodities of Englewood Cliffs, N.J.

No deaths have been linked to the outbreak.

The CDC reports that since late August, 26 people in New York, eight in Pennsylvania, four in Virginia, two in New Jersey, one in Maryland, and one in Arizona have been infected by a strain of the bacteria called human  Salmonella Enteritidis. However, the agency said that illnesses after September 28, 2011 may not have been reported yet due to the time it takes between when a person becomes ill to when the illness is reported. Public health officials are using DNA “fingerprints” to identify people who were sickened by these bacteria.

People infected with salmonella usually have diarrhea, fever, and stomach cramps in the 12 to 72 hours after they are infected and symptoms can last four to seven days, the CDC says. Most people recover without treatment, but some with weakened immune systems, such as older people, children, and people with HIV/AIDS, can become severely ill or even die after being infected.

In August, an outbreak of salmonella killed one person and sickened dozens of others who consumed infected ground turkey. A smaller outbreak of salmonella that sickened 12 people who ate Jennie-O turkey burgers was reported in April.
