HANOI, June 2 (Xinhua) — In the first five months of this year, 694 people in Vietnam suffered from food poisoning, of whom 15 died, according to the country’s Preventive Health Department on Tuesday.

In the same period last year, 806 people were affected by food poisoning, of whom five died.

Between January and May, Vietnam spotted 26,900 dengue fever patients, including three fatalities, 4,921 foot-and-mouth disease cases and 186 viral encephalitis sufferers.

Vietnam currently has 210,500 HIV carriers, of whom 97,154 have become AIDS patients. To date, 98,705 people in the country have died of AIDS-related diseases, the department said. Enditem

Hong Kong – Not to consume a batch of bottled apple juice drink contaminated with patulin


Issue Date 29.5.2020
Source of Information Routine Surveillance Programme of the Centre for Food Safety
Food Product A bottled apple juice drink imported from Australia
Product Name and Description Product name: Cold Pressed Granny Smith Apple

Brand: Presha Fruit

Country of origin: Australia

Importer/Distributor: A.S. Watson Group (HK) Ltd.

Volume: 350ml per bottle

Best-before date: August 7, 2020

Reason For Issuing Alert
  • The test result showed that a sample collected from a supermarket in To Kwa Wan contained patulin at a level of 110 parts per billion (ppb), exceeding the action level of 50 ppb adopted by the CFS. The action level is the same as the standard of the Codex Alimentarius Commission on patulin in apple or apple juice.
  • Patulin mostly occurs in rotten apple and its products. Animal studies showed that ingesting high doses of patulin can induce liver, spleen and kidney damage, as well as toxicity to the immune system. For humans, nausea, gastrointestinal disturbances and vomiting have been reported.
Action Taken by the Centre for Food Safety
  • The CFS has informed the importer, PARKnSHOP (HK) Limited and distributor concerned of the irregularity. The importer and distributor have stopped sale and removed from shelves all batches of the affected product and initiated a recall of the affected batch of the product according to the CFS’ instruction.
  • The CFS will alert the trade, continue to follow up on the case and take appropriate action to safeguard food safety and public health. Investigation is ongoing.
Advice to the Trade Stop using or selling the affected products immediately if they possess them.
Advice to Consumers Not to consume the affected products.

Malaysia – 99 Food Poisoning Cases in Malaysia Attributed to Spoiled Eggs in Pudding

Food Poisoning News

In the city of Kuala Terengganu, Malaysia, there have been 99 food poisoning cases as a result of the consumption of ‘puding buih’ which contained eggs that were two weeks past their expiration date. According to the Center for Disease Control (CDC), refrigerated raw eggs in the shell are safe to eat for up to 3 to 5 weeks. After investigation, the State Local Government, Housing, Health and Environment Committee Chairman, Dr Alias Razak, said that the supplier of the spoiled pudding is a private, small-scale food trader, operating out of his or her own home, like many others who are trying to make an income during this time.

The spoiled ‘puding buih’ was consumed on or around May 22, 2020, by those who reported adverse effects from it. The pudding affected around 20 families and even caused some of them to seek medical attention from nearby public and private hospitals. Most of the people affected by the pudding reported experiencing mild symptoms like stomach aches and diarrhea. However, one person was admitted to an intensive care unit (ICU), but was declared stable shortly after.

Research – Survival of Salmonella in Bathrooms and Toilets in Domestic Homes Following Salmonellosis

Pub Med

The survival and environmental spread of Salmonella bacteria from domestic toilets was examined in homes, where a family member had recently suffered an attack of salmonellosis. In four out of six households tested, Salmonella bacteria persisted in the biofilm material found under the recess of the toilet bowl rim which was difficult to remove with household toilet cleaners. In two homes Salmonella bacteria became incorporated into the scaly biofilm adhering to the toilet bowl surface below the water line. Salmonella enteritidis persisted in one toilet for 4 weeks after the diarrhoea had stopped, despite the use of cleaning fluids. Salmonellas were not isolated from normally dry areas such as, the toilet seat, the flush handle and door handle. Toilet seeding experiments were set up with Salmonella enteritidis PT4 to mimic environmental conditions associated with acute diarrhoea. Flushing the toilet resulted in contamination of the toilet seat and the toilet seat lid. In one out of three seedings, Salmonella bacteria were also isolated from an air sample taken immediately after flushing, indicating that airborne spread of the organism could contaminate surfaces in the bathroom. In the seeded toilet Salmonella bacteria were isolated from the biofilm in the toilet bowl below the waterline for up to 50 d after seeding, and also on one occasion from the bowl water. The results suggest that during diarrhoeal illness, there is considerable risk of spread of Salmonella infection to other family members via the environment, including contaminated hands and surfaces in the toilet area.

Research – Prevalence of E. coli , Salmonella , and Listeria spp. as potential pathogens: A comparative study for biofilm of sink drain environment

Wiley Online


Since knowledge and understanding of waterborne pathogens and their diseases are well illuminated, a few research publications on the prevalence of pathogenic microorganisms in various household sink drain pipes are often not extensively examined. Therefore, this study aims to (a) assess and monitor the densities of the bacterial community in the different natural biofilm that grow on plastic pipelines, (b) to detect Escherichia coli Salmonella , and Listeria spp. from natural biofilm samples that are collected from the kitchen (= 30), bathroom (= 10), laboratories (= 13), and hospital (= 8) sink drainage pipes. Three bacterial species selected were assessed using a culture‐dependent approach followed by verification of isolates using both BIOLOG GEN III and polymerase chain reaction. The estimated number of each bacterium was 122 isolates, while 60, 20, 26, and 16 isolates were obtained from the natural biofilm samples, kitchen, bathroom, laboratories, and hospital, respectively. As for the tests, in all types of biofilm samples, the overall bacterial counts at low temperature (22°C) were higher than those at high temperature (37°C). Meanwhile, coli had the most significant number of bacterial microorganisms compared to the other two pathogens. Additionally, the most massive cell densities of coli Salmonella , and Listeria species were discovered in the biofilm collected from the kitchen, then the hospital. Statistically, the results reveal that there is a positive correlation (≥ .0001) with significance between the sources of biofilm. This work certainly makes the potential of household sink drain pipes for reservoir contagious pathogens more explicitly noticeable. Such knowledge would also be beneficial for prospective consideration of the threat to human public health and the environment.

Research – Modeling dependence of growth inhibition of Salmonella Typhimurium and Listeria monocytogenes by oregano or thyme essential oils on the chemical composition of minced pork

Wiley Online

The aim of this study was to compare the antimicrobial effect of selected essential oils (EOs) at concentration of 1% in minced pork from five different meat cuts (loin, ham, shoulder, neck, and belly) and to assess the influence of the chemical parameters of meat on EO efficiency, determined by the decrease of pathogens in comparison to a control in samples after storage at 3°C/7 d in a vacuum. The inhibition was significant ( < .05) only in minced pork from meat cuts with a fat content lower than 5% (leg, loin and shoulder). Salmonella enterica serovar Typhimurium was more sensitive than Listeria monocytogenes and oregano was more effective than thyme ( < .001). The inhibition of . Typhimurium depended mainly on the fat content (logarithmic dependence) and to a lesser degree on the pH, whereas pH was not found to be a significant predictor in the case of L. monocytogenes . The results of this study show that only lean minced meat (with a fat content max. 5%) is a suitable matrix for pathogen control by EOs.
