Recalled pistachios sold in Canada have been linked to 11 illnesses in the U.S., health officials say.

Wonderful Pistachios of Lost Hills, Calif. voluntarily recalled Wonderful brand roasted pistachios in salted and unsalted form, the Canadian Food Inspection Agency said on its website Thursday.

"Consumers should not consume and retailers, hotels, restaurants and institutions should not sell, serve or use the recalled products," the agency advised with its list of four recalled product codes.

These nuts may have been sold in bulk or in smaller packages with or without a label, CFIA said. The product names could also differ. Those who are unsure if they've  bought the affected products should contact their retailer.

People should throw out the recalled products or return them to the store where they were purchased.

The U.S. Centers for Disease Control and Prevention announced Wednesday that 11 people have been infected with the outbreak strain of salmonella between Dec. 12 and Feb. 9. Two have been hospitalized. No deaths have been reported.

"Collaborative investigative efforts of state, local, and federal public health and regulatory officials indicate that pistachios produced by Wonderful Pistachios of Lost Hills, California are a likely source of this outbreak," CDC said.

Five of eight ill people reported eating Wonderful brand pistachios, the U.S. agency said.

Lab tests also found the outbreak strain of Salmonella Montevideo from samples of raw pistachios collected from Paramount Farms, where the nuts are are grown.

Food contaminated with salmonella may not look or smell spoiled and still make you sick.

Healthy people may experience short-term symptoms such as fever, headache, vomiting, nausea, abdominal cramps and diarrhea. The illness usually lasts four to seven days and most recover without treatment. 

Young children, pregnant women, the elderly and people with weakened immune systems may contract serious and sometimes deadly infections, CFIA said. 

Long-term complications may include severe arthritis.

CFIA said its recall notice was triggered by the U.S. recall and may be associated with the outbreak there.

Wonderful Pistachios said the pistachios were also distributed nationwide in the U.S, and in Mexico and Peru.

There have been no confirmed illnesses in Canada related to the recall, CFIA said.
