Thomson Onion Salmonella Outbreak: Is CDC Missing in Action?

On July 21, 2020, the US Centers for Disease Control and Prevention (CDC) informed the public of an outbreak of Salmonella Newport infections.

On July 24th, the Public Health Agency of Canada (PHAC) informed the public of an outbreak of Salmonella Newport infections apparently caused by the same outbreak strain as CDC was finding in the United States.

At the time of the initial reports, neither agency had determined the source of the outbreak.

On July 30th, PHAC updated its outbreak advisory, informing Canadians that the outbreak was linked to consumtion of red onions imported from the United States. That same day, the Canadian Food Inspection Agency (CFIA) posted a recall notice for red onions imported by Sysco in Western Canada.

Using the Canadian data as its starting point, on July 31st, the US Food and Drug Administration (FDA) and CDC announced that the US outbreak was linked to consumption of red onions produced by Thomson International, Inc. of Bakersfield, California.

Thomson International is a family-owned business, incorporated in California.

On August 1st, Thomson recalled its entire harvest of red, yellow, white, and sweet yellow onions from the 2020 growing season – approximately 18,750 tons of onions. The onions were distributed across the United States and exported to Canada.

CDC issued status updates of the size and scope of the US outbreak on August 3rd, August 7th, August 18th and September 1st, and has not been heard from since.

PHAC issued status updates of the size and scope of the Canadian outbreak on August 2nd, August 7th, August 14th, August 21st, August 31st and September 14th.

By August 7th, FDA had initiated its on-site investigation of Thomson’s Bakersfield facility, looking for the source of the Salmonella Newport contamination. By August 11th, FDA personnel had submitted 370 samples to the agency’s lab for Salmonella testing, including 278 swab samples, 82 onion samples, and 10 miscellaneous environmental samples, according to information obtained by eFoodAlert in response to a Freedom of Information Act request.

Not a single sample contained Salmonella.

The FDA investigation is still in progress. However, with the growing season complete and the packing plant idle, the chances of finding the source of the Salmonella Newport diminish day by day.

As of the last report from CDC, 1012 individuals in 47 states have been infected with Salmonella Newport as a result of having consumed contaminated onions. Only Louisiana, Oklahoma and Vermont have not reported any outbreak cases. Although there have been no deaths associated with this outbreak, 136 (more than 13%) of the victims have required a hospital stay.

In Canada, there have been 506 confirmed cases of Salmonella Newport in seven provinces, and 71 people (14%) have been hospitalized.

Canada v. USA – A Performance Comparison

Why was CDC unable to determine the link between red onions and the Salmonella Newport outbreak until after PHAC had made the connection?

Why has CDC not provided an update to its outbreak status report in three weeks?

Why does Canada appear to have been much harder hit by this outbreak than the United States – 13.7 cases per million Canadians versus only 3.1 per million Americans? Is this due to some quirk of distribution, or have PHAC and its provincial partners done a better job of reporting than CDC and the various state health agencies?

Has the Covid-19 pandemic hit CDC so hard that it no longer has the resources to follow-up on illness outbreaks elsewhere?

 

IF CDC IS MISSING IN ACTION, WHAT DOES THIS MEAN FOR THE HEALTH AND SAFETY OF THE US POPULATION?

Contaminated Peaches from USA Cause Salmonella Outbreak in Canada

Thirty-three Canadians in Ontario (22 cases) and Quebec (11 cases) have become infected with Salmonella Enteritidis after consuming peaches imported from the USA, according to a report released this morning by the Public Health Agency of Canada (PHAC).

Three of the outbreak victims have been hospitalized.

Those infected with the outbreak strain of Salmonella Enteritidis range in age between 0 and 91 years, and 55% of the victims are female.

The outbreak is linked to peaches supplied by Prima Wawona, a California-based company, which has recalled a series of products from the marketplace.

Prima Wawona peaches have also been blamed for an outbreak of Salmonella Enteritidis in the USA, which had sickened 68 individuals in 9 US states as of August 21st, according to the US Centers for Disease Control and Prevention.

On August 22nd, the Canadian Food Inspection Agency (CFIA) issued a Consumer Advisory alerting Canadians to the presence of the recalled peaches in the country and warning that PHAC had identified some illnesses linked to their consumption.

Canadian consumers should avoid purchasing, serving or eating any of the following peaches, or any other food products containing these peaches.

Except for the Extrafresh Peaches, the recall encompasses all products sold from June 1, 2020 forward.

What Consumers Need to Know

  • Do not purchase or consume any peaches listed above. If you are in doubt as to the origin of peaches which you have already purchased, throw them away and disinfect the bin in which they were stored.
  • Some of the peaches may have been supplied to restaurants, hotels, bakeries or various food service establishments, including hospitals and nursing homes and may have been used in salads, desserts or baked goods. It would be prudent to avoid all of these items, unless you can be certain they were produced using peaches not included in this Advisory.
  • If you are suffering from symptoms of salmonellosis, including low-grade fever, stomach cramps, diarrhea, and/or vomiting, consult your healthcare professional. Be prepared to provide information on the food items you consumed during the week before beginning to experience your symptoms

This is the third Canadian foodborne disease outbreak since the beginning of July, all of them linked to consumption of produce imported from the USA. Local produce is readily available during the summer months. Consider supporting your local producers instead of buying imported produce.

US exports Cyclospora outbreak to Canada

From cdc.gov

The Public Health Agency of Canada (PHAC) has received reports of 37 confirmed cases of Cyclospora illnesses in Ontario (26), Quebec (10) and Newfoundland and Labrador (1).

The infections developed between mid-May and mid-June. One person has been hospitalized.

PHAC considers the outbreak to be ongoing, as the agency continues to receive reports of recent illnesses.

At least some of the outbreak victims report having eaten certain Fresh Express brand salad products containing iceberg lettuce, red cabbage and carrots before they fell ill. The rest of the cases are still under investigation.

On June 29, 2020, the Canadian Food Inspection Agency announced a recall of twelve varieties of Fresh Express brand salad products, which had been imported from the USA.

At the time of the recall, no Canadian illnesses associated with these products had been reported to PHAC.

The salad mixes implicated in this outbreak, and in a concurrent 8-state outbreak in the US, were produced at the Fresh Express facility located in Streamwood, Illinois. FDA is conducting a detailed traceback investigation into the source of the contamination.

The Cyclospora outbreak in the US has spread to 8 midwestern states, and has sickened at least 509 individuals as of CDC’s most recent (July 9, 2020) update. Thirty-three people have been hospitalized.

Lab-confirmed cases have been reported in Illinois (151), Iowa (160), Kansas (5), Minnesota (63), Missouri (46) Nebraska (48), North Dakota (6), and Wisconsin (30).

The following companies have announced product recalls in the USA due to Cyclospora contamination. Please click on the links for additional information on recalled products.

The recalled products have been distributed nationwide across Canada and in the following US states: Arkansas, Connecticut, Delaware, Iowa, Illinois, Indiana, Kansas, Kentucky, Massachusetts, Maryland, Maine, Michigan, Minnesota, Missouri, Montana, North Carolina, North Dakota, Nebraska, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Dakota, Tennessee, Virginia, Vermont, Wisconsin, West Virginia, and the District of Columbia. 

Products may have been further distributed and sent to retailers in additional states, according to FDA.

Consumers in Canada and the USA should check their refrigerators and discard any recalled products with production codes beginning with lot code “Z177” or a lower number and have best before dates up to and including 20JUL08 – 20JUL14. This includes Fresh Express brand products in Canada and both Fresh Express and the above-mentioned store brands in the USA.

Symptoms of Cyclospora infection usually begin within one week of consuming a contaminated product and may include: watery diarrhea, abdominal bloating and gas, fatigue (tiredness), stomach cramps, loss of appetite, weight loss, mild fever, and/or nausea. Symptoms may disappear and then return over a period of several weeks without treatment.

If you think you may have eaten a recalled product and are experiencing these symptoms, please consult a health care professional without delay.
