Research – New Nordic report on food safety in seaweed and kelp

Mattilsynet

Together with other food inspectorates in the Nordics, the Norwegian Food Safety Authority has looked at a common Nordic approach to risk management of food safety in seaweed kelp for use as food. The project group recommends that, among other things, a harmonized regulatory framework for food safety should be developed, where seaweed and kelp are classified as a specific group of food, with subgroups for different species.

Interest in seaweed and kelp for use as food is increasing in the Nordic countries and in other countries in Europe. Although seaweed is the largest aquaculture product in the world, there are still no international standards or regulations for food safety in such foods, such as Codex standards or EU legislation.

Nordic species and Nordic waters can have distinctive characteristics that differ from other regions of the world. This must be taken into account in the development of future regulations.

With this as a background, a joint Nordic project was created in 2020, funded by the Nordic Council of Ministers, consisting of the food inspectorates in Denmark, Iceland, the Faroe Islands, Sweden and Norway.

The purpose was to develop a common Nordic approach to risk management of food safety in seaweed and kelp for use in regulatory development in the EU and Codex, and as a background for guidance material in the countries.

The project ended with a report containing updated knowledge about food safety in seaweed and kelp, with special emphasis on Nordic conditions. It describes, among other things, existing production and risk management, which Nordic species are relevant for use as food, their new food status and analysis data from the various countries for heavy metals and iodine.

Research – Small Contaminations on Broiler Carcasses Are More a Quality Matter than a Food Safety Issue

MDPI

Abstract

Depending on the interpretation of the European Union (EU) regulations, even marginally visibly contaminated poultry carcasses could be rejected for human consumption due to food safety concerns. However, it is not clear if small contaminations actually increase the already present bacterial load of carcasses to such an extent that the risk for the consumers is seriously elevated. Therefore, the additional contribution to the total microbial load on carcasses by a small but still visible contamination with feces, grains from the crop, and drops of bile and grease from the slaughter line was determined using a Monte Carlo simulation. The bacterial counts (total aerobic plate count, EnterobacteriaceaeEscherichia coli, and Campylobacter spp.) were obtained from the literature and used as input for the Monte Carlo model with 50,000 iterations for each simulation. The Monte Carlo simulation revealed that the presence of minute spots of feces, bile, crop content, and slaughter line grease do not lead to a substantial increase of the already existing biological hazards present on the carcasses and should thus be considered a matter of quality rather than food safety.

Research – Antimicrobial and Antibiofilm Effect of Commonly Used Disinfectants on Salmonella Infantis Isolates

MDPI

Abstract

Salmonella enterica subsp. enterica serovar Infantis is the most prevalent serovar in broilers and broiler meat in the European Union. The aim of our study was to test the biofilm formation and antimicrobial effect of disinfectants on genetically characterized S. Infantis isolates from poultry, food, and humans. For the biofilm formation under various temperature conditions (8 °C, 20 °C, and 28 °C) and incubation times (72 h and 168 h), the crystal violet staining method was used. The evaluation of the in vitro antimicrobial effect of Ecocid® S, ethanol, and hydrogen peroxide was determined using the broth microdilution method. The antibiofilm effect of subinhibitory concentration (1/8 MIC) of disinfectants was then tested on S. Infantis 323/19 strain that had the highest biofilm formation potential. Our results showed that the biofilm formation was strain-specific; however, it was higher at 20 °C and prolonged incubation time. Moreover, strains carrying a pESI plasmid showed higher biofilm formation potential. The antibiofilm potential of disinfectants on S. Infantis 323/19 strain at 20 °C was effective after a shorter incubation time. As shown in our study, more effective precautionary measures should be implemented to ensure biofilm prevention and removal in order to control the S. Infantis occurrence.

Roanoke

A $14 million settlement has been reached in lawsuits filed by more than 40 people who claimed they or their loved ones were exposed to a deadly viral outbreak while dining at two Famous Anthony’s restaurants.

Details of the agreement — reached on behalf of four patrons who died and others who were sickened when an employee unknowingly spread hepatitis A — became public during a hearing late Thursday in Roanoke’s federal court

USA – Woman’s estate wins big award from Big Olaf in wrongful Listeria death lawsuit – $4 Million

Herald Tribune

SARASOTA — The estate of a 79-year-old Illinois woman who died after eating listeria-tainted ice cream from a Sarasota creamery was awarded $4 million by a U.S. District Court judge in Tampa this week.

The ruling came Tuesday in the wrongful death suit filed last year by Bill Marler, a nationally known foodborne illness attorney who represented the estate of Mary Billman. Marler was retained following Billman’s death on Jan. 29, 2022, and the listeria outbreak identified by federal and state regulators last summer that gained national attention.

Research – French Salmonella outbreak study reveals dual contamination

Food Safety News

Two Salmonella outbreaks were linked to dried sausages produced around the same time by one company in France, according to a study.

The outbreaks affected 44 people who consumed dried pork sausages contaminated by two different types of Salmonella.

Salmonella Bovismorbificans infected a total of 33 people from September to November 2020 and 11 patients with monophasic Salmonella Typhimurium from October to December 2020.

Epidemiological investigations by Santé publique France linked the outbreaks to dried pork sausages from the manufacturer France Salaison produced between September and November 2020. Three recalls of dried pork products were issued in November, affecting eight supermarkets.

Research UK – FSA annual reports shows rise in incidents and recalls

Food Safety News

The number of food incidents, recalls and cases of four pathogens went up over a 12-month period, according to the latest published data.

The Food Standards Agency’s (FSA) annual report and accounts covers performance and activities in 2021/22 across England, Wales and Northern Ireland at a cost of £130.5 million ($160.2 million).

In 2021, cases of Campylobacter and Listeria reported in the UK returned to pre-COVID-19 levels but Salmonella and Shiga toxin-producing E. coli (STEC) O157 stayed lower than pre-pandemic figures. Data for all four pathogens showed an increase compared to more than 49,000 Campylobacter, 566 E. coli, 4,442 Salmonella and 136 Listeria cases in 2020.

A series of related Salmonella outbreaks in 2020 and 2021 were linked to breaded chicken products from Poland and affected more than 1,000 people.

Nine emerging risks were identified including Listeria in enoki mushrooms from Asia which had a 90 percent non-compliance rate.

Food, animal feed and environmental contamination incidents went up by almost 20 percent to 2,336. Pathogenic microorganisms were the leading cause of incidents, allergens were second and pesticide residues third, driven by the Europe-wide incident relating to non-permitted ethylene oxide in sesame products and items containing locust bean gum.

Notifications published in 2021/22 rose to 150 from 136 in the previous period. This included 84 allergy alerts and 66 product recall information notices.

Foodborne disease made up 17 percent of FSA spend on research and evidence programs. PATH-SAFE, a £19 million ($23.5 million) project was started to look at novel methods to improve foodborne disease and antimicrobial resistance surveillance.
