Singapore suspends Putien’s Senoko Kitchen, Yun Nans’ Northpoint branch amid ByteDance office food poisoning outbreak that affected 130

Yahoo News

KUALA LUMPUR, Aug 1 — Two caterers have been suspended by Singapore’s health authorities after a mass food poisoning incident at TikTok owner ByteDance’s office on Tuesday (July 30).

The Ministry of Health (MOH) and Singapore Food Agency (SFA) said that the food business operations of Yun Hai Yao at Northpoint City and Pu Tien Services at Senoko South Road have been suspended until further notice, according to a report on Singapore-based news channel Channel News Asia today.

Health authorities have mandated that both companies clean and sanitise their premises, including all equipment and utensils, and dispose of all ready-to-eat and perishable food items.

All food handlers must retake and pass the Food Safety Course Level 1 and test negative for foodborne pathogens before resuming their duties, the CNA report was quoted as saying.

The food hygiene officer must also retake and pass the Food Safety Course Level 3 before returning to work.

Pu Tien Services serves as the main and catering kitchen for Putien, while Yun Hai Yao operates the Yun Nans restaurant chain, the CNA report said.

Authorities said 130 people reported having gastroenteritis symptoms on Tuesday, with fifty-seven people taken to the hospital.

Seventeen others remain hospitalised but are in stable condition, said the report.

The others have either sought outpatient care, self-medicated, or recovered without any treatment.

Research -Biocontrol Strategy of Listeria monocytogenes in Ready-to-Eat Pork Cooked Ham Using Peptic Hydrolysates of Porcine Haemoglobin

MDPI

Abstract

Listeria monocytogenes is a foodborne pathogen that represents a serious concern for ready-to-eat (RTE) meat products due to its persistence in production facilities. Among the different strategies for the control of this pathogen, the use of antimicrobial peptides derived from food by-products, such as slaughterhouse blood proteins, has emerged as a promising biocontrol strategy. This study evaluated for the first time the use of peptic hydrolysates of porcine hemoglobin as a biocontrol strategy of L. monocytogenes in RTE pork cooked ham. Pure porcine hemoglobin (Hb-P) and porcine cruor (P-Cru) were hydrolyzed using pepsin at different temperatures (37 °C for Hb-P and 23 °C for P-Cru) for 3 h. Then, the hydrolysates were characterized in terms of their degree of hydrolysis (DH), peptide population, color, and antimicrobial activity (in vitro and in situ) against three different serotypes of L. monocytogenes. Reducing the hydrolysis temperature of P-Cru by 14 °C resulted in a 2 percentage unit decrease in DH and some differences in the peptide composition. Nevertheless, the antimicrobial activity (in situ) was not significantly impacted, decreasing the viable count of L. monocytogenes by ~1-log and retarding their growth for 21 days at 4 °C. Although the color of the product was visibly altered, leading to more saturated reddish and yellowish tones and reduced brightness, the discoloration of the hydrolysates can be addressed. This biopreservation approach holds promise for other meat products and contributes to the circular economy concept of the meat industry by valorizing slaughterhouse blood and producing new antilisterial compounds.

Vibrio vulnificus, the emergence of a real danger

ACSA

According to the European Environment Agency, increasing global sea surface temperature (SST) is one of the main physical impacts of climate change. SST in European coastal seas has increased 4–7 times faster than in the oceans over the past decades. This local increase in SST has been linked to outbreaks of Vibrio -associated human illness caused by non-O1/non-O1 Vibrio cholerae39 , V. parahaemolyticus and V. vulnificus in several European countries.

Climate change has also created new ocean currents that favour the spread of vibrios. Inadequate transport and storage of fish and fishery products over long distances, the same sea waters used by ships as ballast and aquaculture all contribute to their expansion. Travellers and animals also play a role. For example, migratory birds can act as vectors for the intercontinental transport of V. cholerae . Once introduced into a new region, they become endemic. Vibrio spp. and mainly the species V. parahaemolyticus and V. vulnificus , have been identified by the European Food Safety Authority (EFSA) as biological hazards with a high probability of becoming emerging in the near future in Europe.

Research – Genetic Diversity in Salmonella enterica in Outbreaks of Foodborne and Zoonotic Origin in the USA in 2006–2017

MDPI

Abstract

Whole genome sequencing is replacing traditional laboratory surveillance methods as the primary tool to track and characterize clusters and outbreaks of the foodborne and zoonotic pathogen Salmonella enterica (S. enterica). In this study, 438 S. enterica isolates representing 35 serovars and 13 broad vehicle categories from one hundred epidemiologically confirmed outbreaks were evaluated for genetic variation to develop epidemiologically relevant interpretation guidelines for Salmonella disease cluster detection. The Illumina sequences were analyzed by core genome multi-locus sequence typing (cgMLST) and screened for antimicrobial resistance (AR) determinants and plasmids. Ninety-three of the one hundred outbreaks exhibited a close allele range (less than 10 allele differences with a subset closer than 5). The remaining seven outbreaks showed increased variation, of which three were considered polyclonal. A total of 16 and 28 outbreaks, respectively, showed variations in the AR and plasmid profiles. The serovars Newport and I 4,[5],12:i:-, as well as the zoonotic and poultry product vehicles, were overrepresented among the outbreaks, showing increased variation. A close allele range in cgMLST profiles can be considered a reliable proxy for epidemiological relatedness for the vast majority of S. enterica outbreak investigations. Variations associated with mobile elements happen relatively frequently during outbreaks and could be reflective of changing selective pressures.
