Research -Food Poisoning May Increase Risk of Crohn’s Disease Later in Life

Medical News Bulletin

Canadian researchers have discovered that exposure to food-borne pathogens that produce acute infectious gastroenteritis, more often known as food poisoning, may enhance the growth of the bacterium adherent-invasive E. coli, which has been associated with Crohn’s disease.

Crohn’s disease is an inflammatory bowel disease characterized by chronic inflammation of the intestines. Patients with the disease experience several symptoms, including cramping, diarrhea, abdominal pain, vomiting, weight loss and fatigue, and have an increased risk of premature death and an increased risk of colorectal cancer. The rate of Crohn’s disease in Canada is 1 in every 150 people, and ranks in the highest globally.

Dozens of workers at the company also fell sick in a similar case five months ago.

Health officials in Ho Chi Minh City are taking food samples from a Chinese-owned garment company to investigate a mass poisoning case that happened on Saturday.

The officials said 109 workers at Worldon Company in Cu Chi District had had to be rushed to hospital after having a lunch of ground fish braised with shrimp, stir-fried vegetables and cabbage soup.

Seven of the workers had to stay in hospital overnight, and doctors said they were suffering from food poisoning.

Dozens of workers at the company also fell sick after lunch in May.

Worldon Vietnam is owned by Shenzhou International, a Chinese clothing manufacturer based in Zhejiang Province in eastern China. The company employs more than 6,000 workers.

Food poisoning has been on the rise in Ho Chi Minh City over the past five years, mostly involving school and factory meals.

Research -Organic Foods Not Automatically Safer Than Conventionally Grown

Food Poisoning Bulletin

A study published in the Journal of Food Protection has found that while consumers think that organic foods are “safer” than conventionally grown or produced foods, the standards applied to those products do not directly address microbial or chemical safety issues. Researchers looked at the CDC’s Foodborne Disease Outbreak Surveillance System in this study. They found that there have been 18 food poisoning outbreaks linked to organic foods from 1992 to 2014.

UK – Scotland -Increased Norovirus – Viral Research

HPS Food Borne Illness - Norovirus -CDC Photo

On 20 October, the European Food Safety Authority (EFSA) published a scientific report on the outcomes of a scientific workshop on foodborne viruses organised jointly by EFSA and the UK Food Standards Agency. The workshop took place earlier this year in London, and brought together academics, clinicians, veterinarians, food industry specialists and regulators with expertise in research, clinical settings and food producing/processing operations.

Against the background of an increasing number of outbreaks caused by foodborne viruses, the participants assessed the state of knowledge in this field. They focused on norovirus, the hepatitis A virus and the hepatitis E virus, which are of great public health concern in the EU. Knowledge gaps and research needs were identified and are summarised in the report.

The report (accessible at http://www.efsa.europa.eu/en/supporting/pub/1103e) by the UK’s Centre for Environment, Fisheries and Aquaculture Science (Cefas) also lists five priorities for further research.

The workshop was organised following a proposal to EFSA’s Advisory Forum by the UK in 2015. [Source: EFSA News Release, 29 October 2016. http://www.efsa.europa.eu/en/press/news/161020]

HPS

On 27 October, Health Protection Scotland (HPS) announced that there had been an increase in levels of norovirus across Scotland. Latest figures showed that NHS boards were experiencing increased norovirus activity.

Health professionals across NHS Scotland are working to reduce the likelihood of outbreaks arising. The public are also being asked to play their part in minimising the spread of the virus. Norovirus is a highly infectious virus that causes outbreaks in the community, healthcare and care settings. It is present all year round but becomes more common in the winter when people stay indoors for longer and in larger groups.

To help reduce the risk of outbreaks in hospitals, care settings and the wider community, HPS urges members of the public who think they have norovirus to stay at home until at least 48 hours after any symptoms have stopped.

As norovirus is so infectious, it is important that everyone plays their part in reducing the risk of outbreaks. To do this, hospitals may suspend access to particular wards to protect patients, staff and visitors from norovirus and to minimise disruption to healthcare services.

HPS will continue to monitor the situation and will support NHS boards as required. [Source: HPS News Release, 27 October 2016. http://www.hps.scot.nhs.uk/news/newsdetail.aspx?id=21916]

Research -Presence of Escherichia coli O157, Salmonella spp., and Listeria monocytogenes in Raw Ovine Milk Destined for Cheese Production and Evaluation of the Equivalence Between the Analytical Methods Applied

Mary Ann Liebert

Italy is one of the main producers and exporters of cheese made from unpasteurized sheep milk. Since raw milk and its derived products are known sources of human infections, cheese produced from raw sheep milk could pose a microbiological threat to public health. Hence, the objectives of the study were: to characterize the potential risk of the presence of pathogens Escherichia coli O157, Listeria monocytogenes, and Salmonella in raw ovine milk destined for cheese production obtained from all the sheep farms (n = 24) in the Marches region (Central Italy) that directly transform raw milk into cheeses and to evaluate the equivalence between the analytical methods applied. A three-step molecular method (simultaneous culture enrichment, species-specific DNA magnetic isolation, and multiplex real-time polymerase chain reaction) was used for milk (n = 143) and cheese (n = 5) analysis over a 3-year period. L. monocytogenes was not detected on any of the farms, while E. coli O157 was found on three farms, although only using the molecular method. Four farms tested positive for Salmonella spp., and Salmonella enterica subsp. diarizonae serovar 61:k:1,5,7 was isolated in one of those cases. This information highlights the need to develop preventative measures to guarantee a high level of consumer safety for this specific product line, and the molecular method could be a time-saving and sensitive tool to be used in routine diagnosis.

Research -Prevalence and tracing of persistent Listeria monocytogenes strains in meat processing facility production chain

Wiley Online Library

Abstract

This work was aimed at determining the occurrence and diversity of Listeria monocytogenes in a traditional meat-processing facility to reveal persistent contamination. A total of 268 samples, including 196 environmental samples and 72 meat samples were collected during a four-year period, and 70 were found to be L. monocytogenes positive. Molecular serotyping of 77 isolates classified these strains into four serogroups, with the majority of 34 strains in serogroup IIa. To reveal the persistent contamination, subtyping by AscI/ApaI-PFGE was applied. Cluster analysis resulted in strain discrimination into 18 profiles. Strains with PFGE/MLST-ST classification as 1/ST9, 2/ST14 and 9/ST2 were predominant and considered persistent. Based on the results of PFGE, a spatial and temporal map of persistent L. monocytogenes contamination was drawn. Subtyping by PFGE was used as a reliable tool to reveal persistent contamination and, complemented with virulence characteristics, can contribute to the improvement of L. monocytogenes control programs in food processing.

Practical application

Listeria monocytogenes is a food-borne pathogen with significant public health and economic impact. This study, focused on prevalence and tracing of L. monocytogenes strains in a traditional meat-processing facility, revealed persistent contamination by the pathogen. Data of PFGE profiling from repeated samplings over a four-year period facilitated to draw a spatial and temporal map of persistent L. monocytogenes strains spreading in a meat-processing facility and, subsequently, will allow optimisation of cleaning and disinfection measures to ensure hygiene. Based on the detection of virulence factors, persistent ECIII and comK prophage-positive strains were observed, indicating a higher risk of contamination by more virulent L. monocytogenes strains. The obtained results clearly indicate, that most attention should be paid to control strategy improvement in the meat processing chain focused preferably on prevention, not only to final products.
