Canada – Research Into E.coli O157 XL Outbreak 2012

Food Safety

The Panel members were appointed by the Governor in Council to undertake an independent review of the beef recall that occurred at XL Foods Inc.‘s plant at Brooks, Alberta between September and October 2012, and to submit a report to the Minister of Agriculture and Agri-Food.

We were asked to establish how the contamination occurred and, moreover, how the Canadian Food Inspection Agency (CFIA, or Agency), its food safety partners, and XL Foods Inc. responded to the situation. Lastly, we were tasked with providing recommendations that would address any findings or conclusions that we had made regarding these matters. We note that such findings or conclusions do not address civil or criminal liability; the standards that we are applying are not legal ones.

Over the course of several weeks, the Panel met with dozens of stakeholders. These included beef producers and processors, health authorities and academics, the retail industry, and union representatives for both the company and the Agency.

In this regard, we were left with a single overarching impression: everyone we interviewed expressed a keen desire to ensure that the food Canadians eat is safe. And they all wanted to be considered partners in the pursuit of that goal.

Research – Listeria monocytogenes Biofilm Formation

Science Direct

The foodborne pathogen Listeria monocytogenes has the ability to produce biofilms in food-processing environments and then contaminate food products, which is a major concern for food safety. The biofilm forming behaviour of 143 L. monocytogenes strains was determined in four different media that were rich, moderate or poor in nutrients at 12°C, 20°C, 30°C and 37°C. The biofilm formation was mostly influenced by temperature, resulting in decreased biofilm formation with decreasing temperature. Biofilm formation was enhanced in nutrient-poor medium rather than in nutrient-rich medium, and especially in nutrient-poor medium significantly enhanced biofilm production was observed early in biofilm maturation underlining the effect of medium on biofilm formation rate. Also serotype had a significant effect on biofilm formation and was influenced by medium used because strains from both serotype 1/2b and 1/2a formed more biofilm than serotype 4b strains in nutrient-rich medium at 20°C, 30°C and 37°C, whereas in nutrient-poor medium the biofilm production levels of serotype 1/2a and 4b strains were rather similar and lower than serotype 1/2b strains. The strains used originated from various origins, including dairy, meat, industrial environment, human and animal, and the level of biofilm formation was not significantly affected by the origin of isolation, irrespective of medium used and temperature tested. A linear model was used to correlate crystal violet staining of biofilm production to the number of viable cells within the biofilm. This showed that crystal violet staining was poorly correlated to the number of viable cells in nutrient-poor medium, and LIVE/DEAD staining and DNase I treatment revealed that this could be attributed to the presence of non-viable cells and extracellular DNA in the biofilm matrix. The significant impact of intrinsic and extrinsic factors on biofilm production of L. monocytogenes underlined that niche-specific features determine the levels of biofilm produced, and insights in biofilm formation characteristics will allow us to further optimize strategies to control the biofilm formation of L. monocytogenes.

 

Food Poisoning Bulletin – Hepatitis A – Killing

FPB

Hepatitis A is hard to kill.  The virus is normally transmitted when an infected person doesn’t wash his or her hands properly after going to the bathroom and then touches food or objects where it can live for a month or more.

USA – CDC Report on Listeria 2009-2011

CDCE.coli O157

This report details the epidemiology of invasive listeriosis, which often leads to bacteremia, meningitis, hospitalization, fetal loss, and death, and calls for actions that could protect the most vulnerable populations. Older adults and pregnant women, particularly pregnant Hispanic women, are at much higher risk than the population at large, as are persons with weakened immunity (2). Preventing infections in these populations can have substantial impact in averting these outcomes. Older adults and persons with weakened immunity, as well as infants and young children, are also prone to many other foodborne illnesses, including campylobacteriosis, salmonellosis, and Shiga toxin–producing E. coli infections (4). Accounting for underdiagnosis and underreporting, an estimated 1,662 cases of listeriosis occur each year (5). No progress in reducing the overall incidence of listeriosis has occurred in over a decade (3,4); renewed prevention efforts are needed from farm to table.

USA – Various Updates on the Berry Hepatitis A Outbreak

Food Poisoning Bulletin

The hepatitis A outbreak associated with Townsend Farms berries sold at Costco has sickened at least 37 people in six states and raised a lot of questions. One of them is how does food become contaminated with hepatitis A?

Food Poisoning Bulletin

The Centers for Disease Control and Prevention has updated the Hepatitis A outbreak associated with Townsend Farms Organic Anti-Oxdant Blend frozen berry and pomegranate mix. Now 49 people are sick with acute Hepatitis A in seven states. And eleven people have been hospitalized. The numbers are most likely going to change every day.

Food Poisoning Bulletin

Harris Teeter is recalling frozen mixed berries that may be contaminated with hepatitis A. The Matthews, NC-based grocery chain said Tuesday that it is removing  Harris Teeter Organics Antioxidant Berry Blend from its stores out of an abundance of caution because its berry supplier is Townsend Farms Inc. which has been associated with an outbreak of hepatitis A that has sickened 37 people in six states. That product contained mixed berrie and pomegranate seeds.

FDA

Prime Food USA, 50st & 1st Ave Building # 57, Brooklyn NY 11232, is recalling Latis Brand Seafood Products due to confirmed and suspected contamination with listeria monocytogenes.

Listeria can cause serious complications for pregnant women, such as stillbirth. Other problems can manifest in people with compromised immune systems. Listeria can also cause serious flu-like symptoms in healthy individuals.
