Ireland – Nearly 7,000 Limerick people impacted by boil water notice that has been in place since May

Independant

Nearly 7,000 Limerick residents have been impacted by a boil water notice since last May.

A boil water notice was issued back on May 13 2023 for all Limerick residents supplied by the Foynes/Shannon Estuary Public Water Supply.

Uisce Éireann explained that the notice was issued to protect the health of the public as the water served by Foynes/Shannon Estuary PWS has been described as potentially unsafe to drink due to the detection of cryptosporidium.

The areas impacted are Askeaton, Foynes, Ballyhahill, Loghill, Ballysteen, Pallaskenry, Kildimo and Shanagolden and surrounding areas, for an estimated residential population of 6,986 people.

What actions should be taken: Use water prepared for drinking when preparing foods that will not be cooked (e.g. washing salads); water can be used for personal hygiene, bathing and flushing of toilets but not for brushing teeth or gargling. Boil water by bringing to a vigorous, rolling boil (e.g. with an automatic kettle) and allow to cool. Cover and store in a refrigerator or cold place. Water from the hot tap is not safe to drink. Domestic water filters will not render water safe to drink. Caution should be taken when bathing children to ensure that they do not swallow the bathing water.

Research – ‘Overlooked’ problem of bacteria in fast-food soda fountains. How risky is that drink?

Posted on October 10, 2023 by | Leave a comment

USA Today

Scientists in Southern California are asking the kind of questions that make soda drinkers uneasy after a recent study that found fast-food soda fountains were serving up high levels of bacteria along with self-serve drinks.

Researchers from Loma Linda University found bacteria levels that surpassed U.S. Environmental Protection Agency regulations for drinking water at fast-food restaurants in the eastern Coachella Valley, where largely low-income, Latino farmworker families have struggled with accessing potable water.

The study, published in August in the journal Drinking Water, found more than 40% of water samples from fast-food soda fountains had coliforms present, an indicator of contamination. The study calls into question the sanitation and maintenance of water from soda fountains, which rely on government and manufacturer standards.

Spain – Hundreds sickened in Spain by water contaminated with parasite

Posted on October 2, 2023 by | Leave a comment

Food Safety News

More than 450 people have been sickened in a Spanish town after drinking and using contaminated water.

Public health officials in Tarazona, in the province of Zaragoza, reported 452 illnesses since early September. Most patients have had a mild illness with symptoms including diarrhea, sometimes vomiting, and a fever.

Analyzes commissioned by Tarazona Council from independent laboratories confirmed the presence of the Cryptosporidium parasite in the Queiles River. Cryptosporidium has also been found in patient samples.

Council staff and public health authorities are trying to find the source, as well as how and where water contamination occurred, so that they can eliminate the problem. At least 45,000 liters of bottled water have been distributed to residents and schools.

Research -Seafood-Associated Outbreak of ctx-Negative Vibrio mimicus Causing Cholera-Like Illness, Florida, USA

Posted on September 30, 2023 by | Leave a comment

CDC

Vibrio mimicus caused a seafood-associated outbreak in Florida, USA, in which 4 of 6 case-patients were hospitalized; 1 required intensive care for severe diarrhea. Strains were ctx-negative but carried genes for other virulence determinants (hemolysin, proteases, and types I–IV and VI secretion systems). Cholera toxin–negative bacterial strains can cause cholera-like disease.

Vibrio mimicus, named because of its close metabolic and genetic similarity to V. cholerae, is recognized globally as a cause of foodborne and waterborne diarrheal disease (1–4). Limited data indicate that V. mimicus incidence is lower than that reported for V. parahaemolyticus and non-O1/non-O139 V. cholerae but comparable to that of V. fluvialis (3,4). Although some V. mimicus strains produce cholera toxin (CTX) or a cholera-like toxin or have genes from the ctx complex, most do not (1,5). Nonetheless, V. mimicus can cause severe, cholera-like illness; the hospitalization rate among case-patients reported in 2014 (the most recent year for which data are available) to the Centers for Disease Control and Prevention is 57% (3). We report a seafood-associated outbreak caused by V. mimicus in Florida, USA, in which 4 of 6 patients required hospitalization

USA – Man dies after contracting Vibrio vulnificus bacteria from fresh oysters in Texas restaurant

Posted on September 13, 2023 by | Leave a comment

Detroit Free Press

Food Illness

The consumption of raw oysters at a Texas restaurant led to the untimely death of a relatively healthy man in his 30s.

The man, contracted a bacterial infection known as Vibrio vulnificus that thrives in warm coastal waters. Bacterial infections like this one are on the rise as water temperature continues to increase in response to climate change.

Vibrio vulnificus bacteria can be found in raw or undercooked seafood, but also naturally occurs in saltwater and brackish water.

You can be infected with Vibrio when an open wound comes into contact with raw or undercooked seafood, its juices, or its drippings or with saltwater or brackish water, the CDC reported.

Research – Cyclospora cayetanensis: A Perspective (2020–2023) with Emphasis on Epidemiology and Detection Methods

Posted on September 6, 2023 by | Leave a comment

MDPI

Abstract

Cyclospora cayetanensis infections are prevalent worldwide, and the parasite has become a major public health and food safety concern. Although important efforts have been dedicated to advance toward preventing and reducing incidences of cyclosporiasis, there are still several knowledge gaps that hamper the implementation of effective measures to prevent the contamination of produce and water with Cyclospora oocysts. Some of these data gaps can be attributed to the fact that access to oocysts is a limiting factor in C. cayetanensis research. There are no animal models or in vivo or in vitro culture systems to propagate the oocysts needed to facilitate C. cayetanensis research. Thus, researchers must rely upon limited supplies of oocysts obtained from naturally infected human patients considerably restricting what can be learnt about this parasite. Despite the limited supply of C. cayetanensis oocysts, several important advances have happened in the past 3 years. Great progress has been made in the Cyclospora field in the areas of molecular characterization of strains and species, generation of genomes, and development of novel detection methods. This comprehensive perspective summarizes research published from 2020 to 2023 and evaluates what we have learnt and identifies those aspects in which further research is needed.

USA – Lehi E. coli Outbreak now stands at 12

Posted on August 22, 2023 by | Leave a comment

Food Poison Journal

An ongoing investigation into recent E. coli cases in Lehi led to the detection of E. coli O157 in samples collected from pressurized irrigation (PI) water sources in Lehi. Samples were taken from a PI reservoir and nine exposure sites on Monday, August 14. E. coli O157 was found in the sediment of the tested reservoir and at five of the exposure sites.

The investigation linked the source of the outbreak to using pressurized irrigation for drinking and recreation, such as running through sprinklers or playing on slip-n-slides. Currently, the Utah County Health Department has reported a total of 12 cases of E. coli. Pressurized irrigation water, unlike culinary water, is not treated, leaving it susceptible to contamination by harmful bacteria, including E. coli. The effects of E. coli can be severe, leading to a range of health issues. Pressurized irrigation water is not connected to the city culinary drinking water system. Using culinary water to water the lawn should not be used as an alternative water source.
