Food recall warning: Various Silk and Great Value brand plant-based refrigerated beverages recalled due to Listeria monocytogenes

How to protect your health

Listeriosis is a foodborne bacterial illness that can affect anyone exposed to a contaminated food product, including the recalled products.

While healthy individuals can fall ill from a Listeria infection, the disease can be fatal for unborn babies, newborns, individuals over age 60, and those with weakened immune systems.

The following advice applies to individuals across Canada:

  • Check to see if you have recalled products in your homes or establishment by looking for the specific product name and size, UPC and codes in the recall alert.
  • Do not consume, serve, use, sell or distribute recalled products or any product made with them.
  • Recalled products should be thrown out or returned to the location where they were purchased. Consumers who are unsure if they have purchased the recalled products are advised to contact their retailer.
  • Do not cook food for other people if you’ve been diagnosed with a Listeria infection or any other gastrointestinal illness.
  • Contact your health care provider if you think you’re experiencing symptoms of Listeria infection.

Those who are most at risk of becoming sick with severe listeriosis include:

  • People with weakened immune systems (unable to fight diseases easily).
  • Adults over the age of 60. The risk increases with age due to a weakening immune system.
  • People who are pregnant, including their unborn or newborn baby.

What are the complication risks?

If you have severe listeriosis, you can develop meningitis (a brain infection) and/or blood poisoning. Severe listeriosis can be fatal.
Although people infected while pregnant may only experience mild, flu-like symptoms, listeriosis can spread to their unborn baby, and it can cause:

  • a miscarriage
    • this is when your baby dies in the womb before the 20th week of pregnancy
  • a stillbirth
    • this is when your baby dies in the womb after 20 weeks of pregnancy (before delivery)
  • a premature birth
  • life-threatening illness in your baby shortly after birth

Symptoms

Symptoms of listeriosis can start as early as 3 days after eating contaminated food. You may have the following symptoms:

  • fever
  • nausea
  • cramps
  • diarrhea
  • vomiting
  • headache
  • constipation
  • muscle aches

In severe cases, the bacteria can spread to the nervous system (the brain, spinal cord and nerves). Symptoms of severe listeriosis include:

  • stiff neck
  • confusion
  • headache
  • loss of balance

Symptoms of severe listeriosis may appear up to 70 days after you have been exposed to Listeria.

Investigation summary

There are 20 laboratory-confirmed cases of Listeria monocytogenes illness linked to this outbreak in:

  • Alberta (1)
  • Ontario (13)
  • Quebec (5)
  • Nova Scotia (1)

People became sick between August 2023 and mid-July 2024. Of the cases reported to us, fifteen people have been hospitalized and three individuals have died. Many people who became sick reported drinking recalled plant-based beverages before their illnesses occurred.

People who became sick are between 7 and 89 years old. Most of them are:

  • adults 50 years of age or older (70%)
  • female (65%)

More recent illnesses may continue to be reported in the outbreak because there is a period between when a person becomes ill and when the illness is reported to public health officials. For this outbreak, the illness reporting period is between 9 and 29 days.

This outbreak may not be limited to the provinces or territories with known illnesses because the recalled plant-based beverages were distributed nationally.

USA – US health officials report a third death in Listeria food poisoning outbreak tied to deli meats

Food Safety News

recalled Boars Head deli meats

A Listeria outbreak traced to Boar’s Head deli meats has claimed another life and sickened more people.

As of Aug. 8, there were 43 confirmed patients across 13 states. All of the patients have required hospitalization. Three of the patients have died. The patients range in age from 32 to 94 years old.

“Epidemiologic, laboratory, and traceback data show that meats sliced at deli counters, including Boar’s Head brand liverwurst, are contaminated with Listeria and are making people sick,” according to an update from the Centers for Disease Control and Prevention.

Listeria Recall: What Your Intestinal Tract Needs You to Know

ACSH

As America threw out bags of Boar’s Head roast beef and corned beef this weekend due to possible Listeria contamination, it focused attention, again, on the safety of our food supply. Food safety is fundamental to a functioning society and the minimum we expect as a country. How are we doing?

Denmark – Outbreak with Salmonella monophasic Typhimurium sequence type 34 in Denmark

SSI

Since April 2024, the Statens Serum Institut has registered an outbreak with 63 cases of Salmonella monophasic Typhimurium. The Statens Serum Institut, the Danish Veterinary and Food Administration and the Norwegian Food Institute DTU are investigating the disease outbreak, which has been decreasing since June. The source of infection in this outbreak is minced beef of Danish origin.

Research – Genetic Diversity in Salmonella enterica in Outbreaks of Foodborne and Zoonotic Origin in the USA in 2006–2017

MDPI

Abstract

Whole genome sequencing is replacing traditional laboratory surveillance methods as the primary tool to track and characterize clusters and outbreaks of the foodborne and zoonotic pathogen Salmonella enterica (S. enterica). In this study, 438 S. enterica isolates representing 35 serovars and 13 broad vehicle categories from one hundred epidemiologically confirmed outbreaks were evaluated for genetic variation to develop epidemiologically relevant interpretation guidelines for Salmonella disease cluster detection. The Illumina sequences were analyzed by core genome multi-locus sequence typing (cgMLST) and screened for antimicrobial resistance (AR) determinants and plasmids. Ninety-three of the one hundred outbreaks exhibited a close allele range (less than 10 allele differences with a subset closer than 5). The remaining seven outbreaks showed increased variation, of which three were considered polyclonal. A total of 16 and 28 outbreaks, respectively, showed variations in the AR and plasmid profiles. The serovars Newport and I 4,[5],12:i:-, as well as the zoonotic and poultry product vehicles, were overrepresented among the outbreaks, showing increased variation. A close allele range in cgMLST profiles can be considered a reliable proxy for epidemiological relatedness for the vast majority of S. enterica outbreak investigations. Variations associated with mobile elements happen relatively frequently during outbreaks and could be reflective of changing selective pressures.
