Scotland – Salmonella in Feeder Mice for Reptiles


28 September 2021

Article: 55/3908

Food Standards Scotland (FSS) and the Food Standards Agency (FSA) are urging reptile owners who have purchased certain feeder mice for their pets, take extra precautions in order to avoid contracting salmonellosis.

Scientists have again confirmed a link between Salmonella detected in feeder mice distributed across the UK by Monkfield Nutrition, and an outbreak of human cases of Salmonella. Retailers must now legally provide customers buying these feeder mice with an information leaflet about the risks of Salmonella infection, and advise on good practice for handling animal food, and ensuring good hygiene in the home.

The outbreak was first investigated in 2015 and has so far resulted in almost 850 reported human cases, mostly, but not exclusively, in those living in households with one or more pet reptiles. FSS and the FSA advise that the risk to the general public is considered to be very low.

Research – Antimicrobial resistance, virulence , Antimicrobial resistance, virulence genes, and biofilm formation in Staphylococcus aureus strains isolated from meat and meat products

Wiley Online

Staphylococcus aureus is an important food pathogen that has the ability to form biofilms. This pathogen has been implicated in foodborne outbreaks associated with the consumption of meat and meat products. Since the role of meat products as reservoirs of antimicrobial resistant S. aureus and biofilm formers has not been studied, this research was conducted to assess the incidence, antimicrobial resistance, and presence of biofilm-forming genes in S. aureus bacteria from meat and meat products. For this purpose, 440 samples of meat and meat products were randomly collected from supermarkets of Shahrekord city, Iran. S. aureus isolates were highlighted and identified through biochemical tests. All S. aureus isolates were profiled for susceptibility to 14 antibiotics and the corresponding resistance genes were searched. The quantification of biofilm formation followed by a screening of biofilm formation encoding genes was done. Of the 440 samples collected, 61 were found to contain S. aureus. The incidence of S. aureus among the beef meat (16/61) was the highest followed by its incidence in sausage (10/61) and lunch meat (9/61). At least one isolate of S. aureus carries one of the following resistance gene blaZmecAtet KlinAtetMerm AermB, and aac A-D. High distribution of icaAicaBicaCicaDclfB, and clfA, biofilm formation genes and Enterotoxin encoding genes seasebsec, and sed. The ability of biofilm production and the presence of virulence determinants in the genome of S. aureus can contribute to their pathogenicity. This research demonstrated the roles of meat and meat products as reservoirs of biofilm-forming and antimicrobial-resistant strains of S. aureus. This poses a food safety and public health problem. However, further work needs to be done to better understand the implication of icaABCD biofilm forming genes present in S. aureus from meat and meat products in their resistance.

India – Delhi govt”s food safety dept to start campaign to check buckwheat flour stocks ahead of Navratri – Aflatoxin

Outlook India

New Delhi, Sep 25 (PTI) Delhi government”s Food Safety department will run a campaign ahead of Navrati festival next month to check the stocks of buckwheat flour in the national capital, officials said on Saturday.

Buckwheat flour, popularly known as ”kuttu atta”, if infected with fungus can cause food poisoning owing to development of aflatoxin in it.

Last April, cases of illness due to consumption of spoiled ”kuttu atta” were reported from Delhi”s Kalyanpuri, Trilokpuri and Mehrauli areas, officials said.

“People who consume spoiled ”kuttu atta” may fall ill. So, they should prefer to use packed ”kuttu” four to avoid chances of any fungal infection.,” said Neha Bansal, food safety commissioner of Delhi government.

The loose quantities of these buckwheat flour, if stored in unhygienic condition for long, may develop fungal growth and also get infested with insects. The fungus produces aflatoxin which is harmful for health, she said.

“In view of use of ”kuttu” flour on a large-scale during Navratri. the Food Safety department will conduct special inspection drive ahead of the festival to ensure shopkeepers do not have ”kuttu atta” unfit for consumption,” Bansal said.

The food safety officers in the districts have been asked to visit marketplaces and check samples of buckwheat flour to ensure it is not spoiled. The drive will start soon, said another officer of the department.

”Kuttu” flour is used to cook food by people holding fast on the nine days of Navratri festival. The festival this year will beginning from October 7.

Nearly 500 residents of Kalyanpuri and Trilokpuri in east Delhi had to be admitted to different hospitals in April this year. They had consumed food cooked with ”kuttu” flour after which they had complained of stomachache, vomiting and headache and were treated in hospitals.

Local police had registered a case against a shopkeeper and also arrested him for selling rotten buckwheat flour to the locals in the area.

USA – Legionnaires’ Disease outbreak in New Jersey ongoing, Additional cases reported

Outbreak News Today


The New Jersey Department of Health (NJDOH) reported this week four cases of Legionnaires’ disease in Hamilton Township, Mercer County between May-August 2021, along with an additional reported case from November 2020.

State and local health officials continue to work closely to investigate these cases as part of a larger investigation, which was initiated in August 2020 following a reported cluster of four cases.

Hamilton Township reported two deaths in August 2020 and an additional death was reported late last month in an elderly township resident among the nine reported cases.

Legionnaires’ disease is a type of pneumonia that people can get after breathing in aerosolized water (small droplets of water in the air) containing Legionella bacteria. Symptoms of Legionnaires’ disease include cough, shortness of breath, fever, muscle aches, and headaches which are similar to symptoms caused by other respiratory infections, including COVID-19.

Norway – Analyzes of nutrients, heavy metals and mycotoxins in cereal products 2021


The Institute of Marine Research (HI) has, on behalf of the Norwegian Food Safety Authority, performed analyzes of nutrients, heavy metals and mycotoxins in grain products. The purpose of the project “Analyzes of nutrients, heavy metals and mycotoxins in grain products” is to obtain nutrient values ​​for the Food Table and control the products for foreign substances.

What we investigated:
  • The analyzed products are; oatmeal, organic oatmeal, sifted wheat flour, spelled wheat flour, organic wheat flour, whole wheat flour, sifted rye flour, whole rye flour, finely ground barley flour and bran.
  • The producers: AXA, Kolonihagen, Møllerens and Regal.
  • A total of 45 aggregate samples. Each sample consisted of three different batches from each manufacturer.
Period: The analyzes were performed in the period November-December 2019 (sample 1), and in August-September 2020 (sample 2) and five grain products in February 2021 (sample 3).
What we were looking for: The project has provided analysis data for the content of nutrients and foreign substances in grain products from the grocery trade.

 The project has provided analytical values ​​for ash, protein, fat, fatty acids, sugars, starch, dietary fiber, β -carotene, thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pyridoxine (B6), folate, vitamin C , vitamin E, vitamin K1, vitamin K2, calcium, magnesium, sodium, potassium, phosphorus, iron, zinc, selenium, iodine, arsenic, cadmium, lead and mercury, and the mycotoxins deoxynivalenol (DON), zearalenone, T2 HT2 and enniatin for 40 grain products. The grain products in sample 3 (5 products) were only analyzed for fat, protein, ash, starch and dietary fiber.

What we found: The results show that the levels of the heavy metals in the cereal products analyzed are below the limit values ​​that apply to arsenic, lead, cadmium, mercury and mycotoxins.

The results show a higher content of dietary fiber in Norwegian grain products than before. This can be explained by the use of an analysis method (AOAC 2009.1) that includes several dietary fiber compounds.

The Norwegian Food Safety Authority will inform affected companies about the analysis project.
