Research – Study reveals Botulism impact in Italy

Food Safety News

kswfoodworld

Italian researchers have looked at botulism trends over two decades including a large outbreak in 2020.

Italy has one of the highest botulism rates in Europe with one factor being a strong home canning tradition in the country. From 1986 to September 2022, 406 botulism incidents involving 599 people were laboratory confirmed.

The study described the surveillance system as well as information on botulism cases reported by local health services and those from hospital discharge forms from 2001 to 2020.

Botulism is a rare but life-threatening condition caused by toxins produced by Clostridium botulinum bacteria. In foodborne botulism, symptoms generally begin 18 to 36 hours after eating a contaminated food. However, they can start as soon as six hours after or as long as 10 days later.

Symptoms can include general weakness, dizziness, double-vision, and trouble speaking or swallowing. It paralyzes respiratory muscles so most patients must be placed on life support. Difficulty breathing, weakness of other muscles, abdominal distention and constipation may also occur. People experiencing these problems should seek immediate medical attention.

USA – More Listeria cases linked to Enoki Mushrooms

Food Poison Journal

Epidemiologic and laboratory data show that enoki mushrooms are contaminated with Listeria and are making people sick. FDA found two strains of Listeria in an import sample of Utopia Foods brand enoki mushrooms. One strain is linked to the two illnesses that were already included in this outbreak, and the other strain is linked to one additional illness. Both strains are now included in this outbreak investigation.

Since the last update on November 22, 2022, one more illness has been linked to this outbreak. As of January 18, 2023, three people infected with the outbreak strains of Listeria have been reported from three states. Sick people’s samples were collected from October 3, 2022, to October 8, 2022.

Sick people range in age from 30 to 56 years, with a median of 42 years, and 66% are male. Two people are Hispanic, and one person is Asian. All three have been hospitalized, and no deaths have been reported.

Two sick people reported eating enoki mushrooms or eating at restaurants with menu items containing enoki mushrooms. One patient did not report eating enoki mushrooms but reported shopping at various Asian grocery stores.

FDA found the outbreak strains of Listeria in an import sample of Utopia Foods brand enoki mushrooms.

Previously, in December 2022, Missouri state officials conducted routine sampling and found Listeria in a sample of Utopia Foods brand enoki mushrooms. The Listeria found in this sample was not the outbreak strains, and it was not linked to any reported Listeria illness in the United States. On December 13, 2022, Utopia Foods recalled these enoki mushrooms. On January 13, 2023, Utopia Foods expanded their recall of enoki mushrooms.

Do not eat, sell, or serve recalled enoki mushrooms. CDC also advises people who are pregnant, aged 65 or older, or have a weakened immune system to not eat any raw enoki mushrooms, even if they are not recalled. Instead, cook enoki mushrooms thoroughly before eating.

Hong Kong – Food Safety Tips for Chinese New Year

CFS

Choosing and handling Chinese New Year foods and snacks

While purchasing or preparing new year foods, purchase them from reputable retail outlets. Buy sweetened lotus seeds and pistachio with natural colour and avoid those looking extraordinarily white because they may have been bleached with chemicals. Avoid buying melon seeds that are too glossy as they may contain mineral oil, which may cause gastrointestinal discomfort.

You should check the expiry date before buying any prepackaged festive items like puddings, sesame balls and sweets, and make sure the packaging is intact. Note the hygienic condition of the shop and the food containers and the hygiene practices of the staff, when buying unpackaged items like crispy triangles, sweetened dried fruits and melon seeds.

After purchase, pre-cooked foods like puddings should be stored in the refrigerator as soon as possible and be consumed before the “use by” date shown on the package. Fried festive foods such as sesame balls and crispy triangles should be kept in air-tight containers and stored in the refrigerator or in a cool, dry place.

Melon seeds and nuts are often served during the Chines Year. However, these foods contain hard hulls. Cracking melon seeds and nuts with your own teeth can result in tooth damage. Use a seed or nut cracker instead. Nut are also often used in making Chinese New Year foods. Should you be allergic to nuts or have other food allergy , read food allergen information on food labels to identify if any food or food ingredients of your allergic concern are present in the food. Avoid the food or food ingredients which you are allergic to.

Keep poon choi at safe temperatures

Chinese New Year is a great time of year to have ‘winter warmers’ such as poon choi when we host large gatherings. These dishes are often prepared through bulk cooking ahead of time, due to the large number of portions required. Poon choi contains various food ingredients and requires complicated and long preparation procedures such as cutting, marinating, precooking and cooling and finally re-heating. If the food is left at room temperature for too long after precooking, foodborne pathogens can multiply and some can even produce heat-stable toxins which are not readily eliminable by reheating.

Therefore, it is important to store food properly by storing precooked ingredients at 4°C or below to prevent the formation of toxins, cool down the precooked ingredients by dividing into small portions, placing in shallow containers or placing in ice bath. Reheating foods thoroughly to the core temperature of at least 75°C or above. Keep hot food above 60°C if it is not consumed immediately. Do not leave reheated food at room temperature for long, and discard it if held at room temperature for more than four hours. Of note, heat from the heat source may not be evenly distributed in a large poon choi during reheating, therefore requiring more time to bring poon choi to a boil before eating.

Safe handling of leftovers

Large holiday meals could leave you with leftovers, such as rice cake and puddings, to dig in for days. For the sake of food safety, all perishables should be refrigerated within two hours of being cooked or cooled, and discard items that have been left out for longer than four hours. To minimise spoilage, leftovers should be kept in clean and airtight containers, and refrigerated within two hours of finishing preparation. All leftovers should be reheated thoroughly with the core temperature of food reaching at least 75°C, and they should only be reheated once. Take note of the expiry dates of the food items before consumption. Food beyond its “use by” date should be discarded while be wary of the quality of food beyond the “best before” date.

Stop eating and discard puddings or other food that are found mouldy or with an abnormal taste. Abnormal taste indicates that the puddings have perished due to improper or prolonged storage. Remember, a “sniff test” is not an appropriate method for testing if food is safe to eat, as food can look and smell fine even after the “use by” date has passed. Any leftovers that have been kept in the refrigerator for more than three days should be disposed.

Research – Microbiological safety of aged meat

EFSA

Abstract

The impact of dry-ageing of beef and wet-ageing of beef, pork and lamb on microbiological hazards and spoilage bacteria was examined and current practices are described. As ‘standard fresh’ and wet-aged meat use similar processes these were differentiated based on duration. In addition to a description of the different stages, data were collated on key parameters (time, temperature, pH and aw) using a literature survey and questionnaires.

The microbiological hazards that may be present in all aged meats included Shiga toxin-producing Escherichia coli(STEC),Salmonella spp., Staphylococcus aureus, Listeria monocytogenes, enterotoxigenic Yersinia spp., Campylobacter spp. and Clostridium spp. Moulds, such as Aspergillus spp. and Penicillium spp., may produce mycotoxins when conditions are favourable but may be prevented by ensuring a meat surface temperature of−0.5 to 3.0°C, with a relative humidity (RH) of 75–85% and an airflow of 0.2–0.5 m/s for up to 35 days.

The main meat spoilage bacteria include Pseudomonas spp., Lactobacillus spp. Enterococcus spp., Weissella spp., Brochothrix spp., Leuconostoc spp. Lactobacillus spp., Shewanella spp. and Clostridium spp. Undercurrent practices, the ageing of meat may have an impact on the load of microbiological hazards and spoilage bacteria as compared to standard fresh meat preparation. Ageing under defined and controlled conditions can achieve the same or lower loads of microbiological hazards and spoilage bacteria than the variable log10increases predicted during standard fresh meat preparation. An approach was used to establish the conditions of time and temperature that would achieve similar or lower levels of L. monocytogenes and Yersinia enterocolitica (pork only) and lactic acid bacteria(representing spoilage bacteria) as compared to standard fresh meat. Finally, additional control activities were identified that would further assure the microbial safety of dry-aged beef, based on recommended best practice and the outputs of the equivalence assessment.

Taipei – Nearly 140,000 seek treatment for diarrhea – Norovirus

Taipei Times

Nearly 140,000 people sought medical treatment for diarrhea last week, as 64 clusters of diarrhea cases were reported over the past four weeks, the Centers for Disease Control (CDC) said in a news release on Monday, advising people to maintain good hand hygiene and food safety practices during the Lunar New Year holiday.

From Jan. 8 to Saturday last week, 139,728 people went to see a doctor for diarrhea — higher than the 104,114 and 116,497 cases reported in the same period last year and in 2021 respectively, the CDC’s surveillance data showed.

A total of 64 clusters of diarrhea cases were also reported in the past four weeks, higher than the 54 clusters reported in the same period last year, it said.

Switzerland – One died in a Swiss Listeria monocytogenes outbreak traced to smoked fish

Food Safety News

Swiss authorities have revealed a Listeria outbreak sickened 20 and killed one person in 2022.

The Federal Office of Public Health (OFSP), Federal Food Safety and Veterinary Office (OSAV), and cantonal, or regional, authorities detected an outbreak of listeriosis in July 2022 and identified smoked trout as the source.

In early July, an unusually high number of Listeria monocytogenes cases were reported to OFSP. Whole genome sequencing (WGS) confirmed they were linked.

As part of an investigation carried out with OFSP, patients were interviewed and evidence pointed to smoked trout produced by one company.

Cantonal food authorities carried out an inspection of the firm in the canton of Thurgovie, also known as Thurgau, which found the bacteria in smoked trout and in the production environment. WGS matched the isolates from food samples and patients, confirming the link.

In July, smoked fish from the company Kundelfingerhof was withdrawn from sale and recalled from stores such as Coop, Migros, and Volg.
