New Zealand – Smoked mussels recalled due to possible presence of Listeria

mpi

New Zealand Food Safety is supporting Blackbeards Smokehouse Ltd in its recall of Blackbeards Smokehouse brand smoked mussels due to the possible presence of Listeria.

The following Blackbeards Smokehouse brand smoked mussels with a batch number of 076/015 and best before date of 27/02/2023 are affected by this recall:

  • Smoked Mussels Chilli & Lime 210g
  • Smoked Mussels Coromandel Gold 210g
  • Smoked Mussels Garlic & Dill 210g
  • Smoked Mussels Natural Smoked 210g

“Listeriosis can be serious for vulnerable groups, such as pregnant people and their unborn babies, newborns, the elderly, and those with weakened immune systems.

“It is particularly dangerous during pregnancy as it can cause miscarriage, premature labour or stillbirth, and infection in the unborn baby.

“Infection in healthy adults is unlikely to be severe, causing mild diarrhoea and flu-like symptoms within a few days of eating contaminated food.

“It can be returned to the place of purchase for a refund. If you are unable to do this, the product should be thrown out,” says New Zealand Food Safety deputy director general Vincent Arbuckle.

If you have consumed any of these products and are concerned for your health, contact your health professional or call Healthline 0800 61 11 16.

For up-to-date details and the list of stores and products affected, go to our food recall page.

The affected products are sold at the following stores:

  • Farro Fresh (North Island)
  • Four Square Coromandel
  • Fresh Choice Papamoa
  • New World Albany
  • Raw Food Market Waiheke
  • Supie Auckland
  • Vetro Rotorua

There may be more stores and products affected, so for up-to-date details, go to our food recall page.

The product is being removed from stores and has not been exported.

The product under recall was identified through routine testing and there have been no reports of associated illness.

“As is our usual practice, we will be working with the company to understand how the contamination occurred and prevent its recurrence,” Mr Arbuckle said.

Research – Exploring Possible Ways to Enhance the Potential and Use of Natural Products through Nanotechnology in the Battle against Biofilms of Foodborne Bacterial Pathogens

MDPI

Abstract

Biofilms enable pathogenic bacteria to survive in unfavorable environments. As biofilm-forming pathogens can cause rapid food spoilage and recurrent infections in humans, especially their presence in the food industry is problematic. Using chemical disinfectants in the food industry to prevent biofilm formation raises serious health concerns. Further, the ability of biofilm-forming bacterial pathogens to tolerate disinfection procedures questions the traditional treatment methods. Thus, there is a dire need for alternative treatment options targeting bacterial pathogens, especially biofilms. As clean-label products without carcinogenic and hazardous potential, natural compounds with growth and biofilm-inhibiting and biofilm-eradicating potentials have gained popularity as natural preservatives in the food industry. However, the use of these natural preservatives in the food industry is restricted by their poor availability, stability during food processing and storage. Also there is a lack of standardization, and unattractive organoleptic qualities. Nanotechnology is one way to get around these limitations and as well as the use of underutilized bioactives. The use of nanotechnology has several advantages including traversing the biofilm matrix, targeted drug delivery, controlled release, and enhanced bioavailability, bioactivity, and stability. The nanoparticles used in fabricating or encapsulating natural products are considered as an appealing antibiofilm strategy since the nanoparticles enhance the activity of the natural products against biofilms of foodborne bacterial pathogens. Hence, this literature review is intended to provide a comprehensive analysis of the current methods in nanotechnology used for natural products delivery (biofabrication, encapsulation, and nanoemulsion) and also discuss the different promising strategies employed in the recent and past to enhance the inhibition and eradication of foodborne bacterial biofilms.

Research – Microbial Dynamics in Mixed-Culture Biofilms of Salmonella Typhimurium and Escherichia coli O157:H7 and Bacteria Surviving Sanitation of Conveyor Belts of Meat Processing Plants

MDPI

Abstract

Biofilm formation can lead to the persistence of Salmonella Typhimurium (ST) and E. coli O157:H7 (O157). This study investigated the impact of meat processing surface bacteria (MPB) on biofilm formation by O157 (non-biofilm former; NF) and ST (strong biofilm former; BF). MPB were recovered from the contacting surfaces (CS), non-contacting surfaces (NCS), and roller surfaces (RS) of a beef plant conveyor belt after sanitation. O157 and ST were co-inoculated with MPB (CO), or after a delay of 48 h (IS), into biofilm reactors containing stainless steel coupons and incubated at 15 °C for up to 144 h. Coupons were withdrawn at various intervals and analyzed by conventional plating and 16S rRNA gene amplicon sequencing. The total bacterial counts in biofilms reached approximately 6.5 log CFU/cm2, regardless of MPB type or development mode. The mean counts for O157 and ST under equivalent conditions mostly did not differ (p > 0.05), except for the IS set at 50 h, where no O157 was recovered. O157 and ST were 1.6 ± 2.1% and 4.7 ± 5.0% (CO) and 1.1 ± 2.2% and 2.0 ± 2.8% (IS) of the final population. Pseudomonas dominated the MPB inocula and biofilms, regardless of MPB type or development mode. Whether or not a pathogen is deemed BF or NF in monoculture, its successful integration into complex multi-species biofilms ultimately depends on the presence of certain other residents within the biofilm.

Research – Prevalence of Foodborne Viruses in Berries Harvested in Canada

MDPI

Abstract

It is known that the transmission of different foodborne viruses can occur either via discharge of contaminated water close to the production environment or via close contact with animal feces. Cranberries are intimately associated with water throughout their production cycle, and blueberries grow close to the ground which could lead to contact with wildlife. The aim of this study was to evaluate the prevalence of human norovirus (HuNoV GI and GII), hepatitis A virus (HAV) and hepatitis E virus (HEV) in two berries produced commercially in Canada. The detection of HuNoV and HAV on RTE cranberries and of HEV on wild blueberries was evaluated using the ISO method 15216-1:2017. Only 3 of 234 cranberry samples tested positive for HuNoV GI (3.6, 7.4, 5.3 genome copies/g, respectively) and all were negative for HuNoV GII and HAV. PMA pre-treatment and sequencing confirmed the absence of potential intact HuNoV GI particles on cranberries. None of the 150 blueberry samples tested positive for HEV. Overall, the prevalence of foodborne viruses in RTE cranberries and wild blueberries harvested in Canada is low, making these products relatively safe for consumers.
