Research – Biofilm-forming ability of pathogenic strains isolated from retail food in Poland

Journal of Food Protection

Biofilms have a significant impact on food safety in the food industry. Many foodborne outbreaks have been associated with pathogenic strains that can form a biofilm. The present study aimed to examine the ability to form biofilms by pathogenic strains collected from retail food samples under the Official Control and Monitoring Program in Poland. Biofilm formation was assessed by the qualitative detection of EPS production on Congo Red Agar, tube method, crystal violet biofilm assay, and MTT assay. A total of 40 isolates from food samples (10 strains for each of the species Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, and Bacillus cereus ) were examined. . . The study classifies strains as adherent strain, slightly adherent, nonadherent (A, SA and N); as weak, moderate, and strong biofilm formation (WBF, MBF and SBF); and weak, moderate, and high metabolic activity (WMA, MMA and HMA). Incubation conditions and time influenced the biofilm levels formed. Moreover, growth medium had a significant impact on biofilm formation. Results showed that 22.5% strains demonstrated A type in LBB and 77.5% SA type in LBB in the test tube while the stronger adhesion was obtained in BHI with 2% sucrose. Among the isolates incubated in the BHI medium with 2% sucrose, A type was observed in 60% of isolates (60%).. CV assay result show that the after 24 h incubation in LBB, SBP was 7,5% while after 48 h – 37.5% tested strains. For BHI medium supplemented with 2% sucrose after 24 h incubation strains 42.5% was classified as SBP and 37.6% after 48h.MTT assay result indicate that 15% strains incubate in LBB (24h) was HMA, and after 48h incubation time HMA show 25%. For BHI medium supplemented with 2% sucrose after 24 h or 48 h incubation strains 70% and 85 % was classified as HMA.

Research – Aspergillus mycotoxins and their effect on the host

Pub Med

Abstract

Aspergillus fumigatus is known to produce various immunosuppressive mycotoxins including gliotoxin. However, none of these mycotoxins has been confirmed as being directly related to the pathogenesis of aspergilli. Recent studies have made substantial progress in the determination of mycotoxins as virulence factors. Gliotoxin was found to be produced much faster than previously believed under certain culture conditions, such as at 37 degrees C and under high oxygen content, which is close to the environment in the host. Gliotoxin was also found to be detectable in the sera of aspergillosis mice and of aspergillosis patients. Based on these findings, it is becoming evident that gliotoxin is produced in the infected organs of patients of aspergillosis at a significant level. In addition to these known mycotoxins, A. fumigatus produces many mycotoxins apparently different from known toxins. From the aspect of gene analysis, the deletion of laeA was found to block the expression of metabolic gene clusters such as sterigmatocystin, and the gene is also expected to be related to the production of gliotoxin. The significance of mycotoxins as virulence factors will hopefully be clarified in the near future.

Research – Survival of toxigenic Escherichia coli on chamomile, peppermint, green, black, ginger, and cinnamon teas during storage and brewing

Wiley Online

In this study, the persistence of toxigenic Escherichia coli (E. coli ) on dried chamomile, peppermint, ginger, cinnamon, black and green teas stored under 4, 10, and 25°C was determined. The E. coli survival rate in ginger and cinnamon teas decreased below 0 on Day 5. In the other tested teas, E. coli survivability showed a downward trend over time, but never dropped to 0. Chamomile tea retained the greatest population of viable E. coli . Meanwhile, die‐off of E. coli was higher at 25°C compared to lower temperatures. Additionally, fate of E. coli during brewing at 60, 70 and 80°C was evaluated. The E. coli population was reduced to below 2 Log colony forming units (CFU)/g after 1 min at 80°C, At the same time, the E. coli survival at 60°C was higher than that at 70°C in all tested teas. The data indicated that if E. coli survives after storage of prepared teas, it may also survive and grow after the brewing process, especially if performed using temperatures <80°C. Finally, we analyzed the correlations between temperature, time, tea varieties and E. coli survival, and successfully constructed a random forest regression model. The results of this study can be used to predict changes in E. coli during storage and fate during the brewing process. Results will form the basis of undertaking a risk assessment.

Research – Study suggests green tea extracts could reduce risk of infection with diarrhoea-causing Norovirus

First Post

Scientists also found that green tea extract in combination with chitosan films can reduce levels of bacteria such as E coli and L innocua to undetectable levels after 24 hours of exposure

It’s not uncommon for one to get an upset stomach occasionally, particularly after eating outside food. This is often the result of different kinds of bacteria and viruses present in the food items. In a research, published in the International Journal of Food Science on 4 July 2020, scientists found that green tea extracts can help in reducing the risk of getting infected with a diarrhoea-causing virus known as norovirus.

Pakistan – Aflatoxins: A peril which limits the export of maize crop from Pakistan

Cabi Blog

The agriculture sector is one of the most climate-sensitive sectors of Pakistan’s economy. It responds to temperature, precipitation, soil radiation, etc., which are directly associated with climate change. Rising temperature, uneven distribution of precipitation, floods, droughts, and other climatic disasters have affected human life along with socio-economic sectors of the world.

In Pakistan, maize is one of the important cereal crops which contributes 2.2 percent to the valued added products and 0.4 percent to the GDP. It is grown on an area of 1251 hectares with production of 5901 tonnes. In recent years, some mycotoxins, which we refer as Aflatoxins have been detected in maize crop grown in Pakistan. It has limited the export of Pakistani corn which causes losses in the economic benefit for all the chain actors linked with maize.

On the other hand, its consumption in the domestic market has been increased dramatically as Pakistani feed industry process/mill thousands of tons of maize every year to surge the demand of poultry sector. To address the issue of aflatoxin in maize crop, USDA and USAID joined hands with Pakistan Agricultural Research Council (PARC), Rafhan Maize Products Co. Ltd and CAB International to implement a programme namely ‘Aflatoxin Control in Pakistan’ using a cutting-edge USDA biocontrol technology.

New Zealand – Recall to manage Listeria risk

MPI 

Temuka business Talbot Forest Cheese is recalling a range of products because of a potential risk of contamination with Listeria.

Listeria is commonly found in the environment and can make people sick (listeriosis) if they consume contaminated food.

Infection can be serious for those with poor immunity and for pregnant women, says Ministry for Primary Industries Director of Compliance Gary Orr.

“We’ve received unconfirmed test results indicating the presence of Listeria in one of the products processed at the company’s factory in Geraldine. The company recognizes the potential risk and is working to have the product removed from shelves. We will be working with the company to ensure it is properly managing future risk of product contamination by Listeria.

“The following brands are determining which products are being affected by this issue.

  • Talbot Forest Cheese
  • Cuisine Canteen (FoodHQ)
  • Gibbston Valley Cheese
  • Imperial Foods
  • Pams Finest (Foodstuffs Own Brands Limited)
  • Griffiths

More detail about the specific products affected will be published on MPI’s website tonight.

For more information and photos of the affected products please see our recall page at:

Recalled food products

These products were available at retail outlets across New Zealand. None of the product has been exported.

“We are working with Toi Te Ora Public Health to identify the source of Listeria for the three cases of listeriosis in Tauranga. While it is important to note that there is no evidence at this stage of a link between these products and the cases in Tauranga, it is a timely reminder for those who are more at risk of listeriosis – including pregnant women and their unborn babies, newborn babies, people with weakened immune systems and elderly people – what foods they should avoid. These include the following products:

  • uncooked, smoked or ready-to-eat fish or seafood, including oysters, prawns, sashimi or sushi
  • paté, hummus and tahini-based dips and spreads
  • cold pre-cooked chicken
  • processed meats including ham and all other chilled pre-cooked meat products including chicken, salami and other fermented or dried sausages
  • pre-prepared, pre-packaged or stored salads (including fruit salads) and coleslaws
  • raw (unpasteurised) milk and any food that contains unpasteurised milk
  • soft-serve ice creams

If you or anyone in your household is in an at-risk group, it is especially important to take a few simple food safety precautions:

  • Avoid eating the high-risk foods listed above.
  • Follow good food hygiene practices, such as washing and drying hands before preparing food and after handling or preparing raw foods.
  • Eat freshly cooked or freshly prepared foods.
  • Wash all raw fruit and vegetables very well before eating.
  • Cook foods thoroughly.
  • Refrigerate leftovers immediately and do not keep for more than 2 days. Reheat to steaming hot before eating.

People not in the above risk groups can generally consume these food products safely. However, if they do become infected they may experience very mild diarrhea and flu-like symptoms, generally occurring within a few days of eating Listeria-contaminated food.

For those in the high risk groups, listeriosis typically has an incubation period of 2-3 weeks (or longer) before symptoms appear.

If you are concerned about your health or believe you have been affected, please talk to your doctor.
