Public health officials in the USA and Canda were able to trace the cases back to red onions from the California company.
State officials are urging people not to eat onions from Thomson International, Inc., of Bakersfield, California, after 76 people in 13 OR counties fell ill with matching strains of Salmonella bacteria.
The salmonella newport outbreak tied to red onions is a different strain than another happening in the U.S. which has sickened hundreds of people in 48 states.
Hundreds of Salmonella Newport cases across several states have been linked to a supplier based in Bakersfield, according to an ongoing investigation by the U.S. Food and Drug Administration.
Although red onions are considered "the likely source", OHA said that Thomson has agreed to recall all onions that could have been cross-contaminated with the bacteria.
OHA said that between 400 and 500 cases of salmonellosis are reported in OR every year. While the official statement from the FDA warns that consumers, retailers and restaurants should not eat, sell or serve onions from the company, it did not specify where consumers may need to watch to see if their onions are supplied by Thomson.
Most people with salmonella will recover without antibiotics, DeBess said, but those who think they've gotten diarrhea from eating red onions may want to contact a doctor.
The FDA has advised people to throw away any onions from Thomson International and any onions of unknown origin. These can also have been bought from Sysco on-line or by numerous restaurant areas. Any places that have come in contact with contaminated onions such as countertops, cutting boards and refrigerators should be thoroughly cleaned with due diligence. The Canadian Food Inspection Agency (CFIA) will continue its investigation into other possible importers and additional recalls may follow. The agency says the illnesses began between mid-June and mid-July. The CDC estimates that about 450 persons in the U.S. die each year from acute salmonellosis.
