Cucumbers shipped to 13 U.S. states and five Canadian provinces have been recalled because of potential salmonella contamination, the Food and Drug Administration said this week.

SunFed Produce, based in Arizona, recalled the cucumbers sold between October 12 and November 26, the FDA said Thursday.

No illnesses were immediately reported. People who bought cucumbers during the window should check with the store where they purchased them to see if the produce is part of the recall. Wash items and surfaces that may have been in contact with the produce using hot, soapy water or a dishwasher.

Salmonella can cause symptoms that begin six hours to six days after ingesting the bacteria and include diarrhea, fever and stomach cramps. Most people recover without treatment within a week, but young children, people older than 65 and those with weakened immune systems can become seriously ill.

Earlier this summer, a separate salmonella outbreak in cucumbers sickened 450 people in the United States.
