Ireland – Legionnaires’ disease

HSE

CDC legionella

Legionnaires’ disease is a lung infection you can catch by inhaling droplets of water from things like air conditioning or hot tubs. It’s uncommon but can be very serious.

How you get Legionnaires’ disease

You can catch Legionnaires’ disease if you breathe in tiny droplets of water containing bacteria that cause the infection.

It’s usually caught in places like hotels, hospitals or offices where the bacteria have got into the water supply. It’s very rare to catch it at home.

You can catch it from things like:

  • air conditioning systems
  • spa pools and hot tubs
  • showers, taps and toilets

You cannot usually get it from:

  • drinking water containing the bacteria
  • other people with the infection
  • places like ponds, lakes and rivers

When to get medical help

Urgent advice:Get advice from your GP now if

you have a bad cough and:

  • it does not go away
  • you cannot breathe properly
  • you have severe chest pain
  • you have a high temperature or feel hot and shivery
  • you feel like you have severe flu

These could be symptoms of Legionnaires’ disease.

You should contact your GP and tell them where you have been in the past 10 days, such as if you stayed in a hotel, spa or hospital. Your GP will assess and advise you.

If you are unable to contact a GP and you are very unwell, you may need to go to your emergency department (ED).

Research – Application of chitosan microparticles against human Norovirus

Journal of Food Protection

Human norovirus (HuNoV) is the leading causative agent of foodborne outbreaks and is associated with the second most prevalent cause of waterborne infections in the United States. The goal of this research was to investigate the antiviral activity of chitosan microparticles (CM) against HuNoV GII.4 Sydney and its cultivable surrogate, Tulane virus (TuV), in suspensions mimicking fecally-contaminated water. CM was prepared by crosslinking chitosan molecules with sodium sulfate, and then its anti-noroviral activity was assessed using infectivity assay on TuV and RT-qPCR on TuV and HuNoV. A 3% CM suspension in PBS (pH 7.2) showed binding to TuV particles but with a negligible impact on virus infectivity (p>0.05). TuV and HuNoV suspended in fecal suspensions showed a 1.5-log10 reduction in genomic copies per ml following a 10-min contact time (p<0.05). Despite the negligible impact on viral infectivity, CM moderately binds to virus particles and helps purify environmental water by removing infectious virus particles. In this study, TuV served as a suitable surrogate for HuNoV by showing a similar log10 reduction in fecal suspension. Overall, the outcomes of thisresearch highlight the potential application of CM as a novel, natural treatment to minimize the spread of water-transmitted viral pathogens.

 

USA – Jellystone Park Camp Resort-Yogi on the Lake E. coli O157 Outbreak

Food Poison Journal

The Mississippi State Department of Health (MSDH) has identified several cases of E. coli O157 infection associated with use of the swimming pool and/or splashpad at the Jellystone Park Camp Resort-Yogi on the Lake in Pelahatchie, Miss.

The cases identified so far have exposure dates on the weekend of July 30th through August 1st, but additional exposures may have occurred through August 9, 2021. The pool and splashpad were closed on August 9, 2021.

USA – DC issues Boil Water Advisory for parts of Northeast after E. coli concerns

The District has issued a Boil Water Advisory for portions of the Northeast due to the possibility of elevated levels of E. coli/coliform bacteria.

The advisory was issued Thursday and includes the neighborhoods of Edgewood, Brookland, Fort Lincoln, Woodridge, Queens Chapel, Michigan Park and North Michigan Park. Officials say approximately 14,000 residents have been affected.

The impacted region is approximately:

– East of North Capitol Street

– West of Eastern Avenue

– South of New Hampshire Avenue

– North of New York Avenue

Sweden – Vibrio infection (Sweden July 2021-)

With continued warm temperatures in our bathing waters, there is a risk of growth of vibrio bacteria that are naturally occurring, especially in seawater. To date, 18 cases of more serious vibrio infections in wounds or blood (sometimes called bath ulcer fever) have been reported during the summer. The majority of cases are over 65 years old and more men than women have fallen ill. To prevent cases of illness, bathing is not recommended if you have significant wounds, especially if you are elderly and / or have a weakened immune system.

Figure. The number of cases of bath ulcer infection in Sweden reported per month from 2018-06-01 – 2021-07-28

The bar chart shows that there are now more cases of bathing fever reported for 2021 than during the whole of 2019 and 2020, respectively, and that in 2018 an unusual number of cases were reported during June to September, a total of 76 cases, of which 45 during August.

Research – Legionella – Can Point-of-Use Water Filters Control Legionella & Other Waterborne Pathogens?

Legionella Control

CDC legionella

This expert water safety article looks at the role of point-of-use water filters, and asks if they can be used to control the health risks from legionella and other waterborne pathogens that can contaminate engineered water systems.

The article considers how these specialist water filters work to protect people from legionella and other waterborne pathogens, and where and under what circumstances they should be used.

Can point-of-use water filters control legionella risk?

You might already suspect the answer to that question is yes, but let’s take a more detailed look. The bigger question to answer is how these filters can help maintain water safety standards, and why you might consider installing point-of-use (POU) water filters in a specific building.

We’ll explain more about these high performance water filters here, so you can better understand their role, the scenarios that might call for them, and how they complement rather than replace other water safety control measures.

Ireland – E. coli O26 outbreak sickens young children in Ireland

Food Safety News

Health officials in Ireland are investigating an E. coli O26 outbreak at a childcare facility.

Officials with the Department of Public Health Mid-West of the Health Service Executive (HSE) said the agency is managing the outbreak of Shiga toxin-producing E. coli (STEC) and highlighted the importance of effective hand hygiene and well water treatment.

The agency added that there are fewer than five patients at the childcare facility in Limerick and the incident is under control.

STEC, also known as Verotoxigenic E. coli (VTEC), can cause serious illness in children under 5 and the elderly. The serious outcomes of illness shows the importance of hand hygiene before and after preparing food and after contact with farm animals and their environment, said officials.
