Water water everywhere, but is it safe?

Potable water and the U.S. Centers for Disease Control: two things we take for granted.

CDC reports that during 2013–2014, a total of 42 drinking water–associated outbreaks were reported, resulting in at least 1,006 cases of illness, 124 hospitalizations, and 13 deaths. Legionella was responsible for 57% of outbreaks and 13% of illnesses, and chemicals/toxins and parasites together accounted for 29% of outbreaks and 79% of illnesses. Eight outbreaks caused by parasites resulted in 289 (29%) cases, among which 279 (97%) were caused by Cryptosporidium and 10 (3%) were caused by Giardia duodenalis. Chemicals or toxins were implicated in four outbreaks involving 499 cases, with 13 hospitalizations, including the first outbreaks associated with algal toxins.

To provide information about drinking water–associated waterborne disease outbreaks in the United States in which the first illness occurred in 2013 or 2014 (https://www.cdc.gov/healthywater/surveillance/drinking-surveillance-reports.html), CDC analyzed outbreaks reported to the CDC Waterborne Disease and Outbreak Surveillance System through NORS (https://www.cdc.gov/nors/about.html) as of December 31, 2015. For an event to be defined as a waterborne disease outbreak, two or more cases must be linked epidemiologically by time, location of water exposure, and illness characteristics; and the epidemiologic evidence must implicate water exposure as the probable source of illness. Data requested for each outbreak include 1) the number of cases, hospitalizations, and deaths; 2) the etiologic agent (confirmed or suspected); 3) the implicated water system; 4) the setting of exposure; and 5) relevant epidemiologic and environmental data needed to understand the outbreak occurrences and for determining the deficiency classification.§ One previously unreported outbreak with onset date of first illness in 2012 is presented but is not included in the analysis of outbreaks that occurred during 2013–2014.

Public health officials from 19 states reported 42 outbreaks associated with drinking water during the surveillance period (Table 1) (https://www.cdc.gov/healthywater/surveillance/drinking-water-tables-figures.html).

One outbreak reported during 2013–2014 in an individual system led to 100 estimated illnesses associated with a wedding. The public health challenges highlighted here underscore the need for rapid detection, identification of the cause, and response when drinking water is contaminated by infectious pathogens, chemicals, or toxins to prevent and control waterborne illness and outbreaks.

‘Many sick’ from crypto in Norway

Thanks to our Norwegian correspondent, we now know the Norwegian Food Safety Authority was notified on September 26, 2017, of a Cryptosporidium outbreak, and after talking to the sick, they could narrow the time of infection to 14-16. September,

The Food Safety Authority believes the people were infected at the Taqueros Taco & Tequila restaurant (because when I think Norway, I think tacos and tequila, not schnapps and raw fish).

The restaurant decided to shut one day to wash the premises when they heard about the outbreak and that the infection came from them.

The source of the infection was not found, but the Norwegian Food Safety Authority emphasizes that they do not discourage people from eating at the restaurant.

Specialist warden Erik Wahl in Mattilsynet in Trondheim and surroundings said, “We have reason to believe that the infection is now gone, as no people who have become ill after September 16 have not been reported. We have no reason to discourage people to eat at this restaurant.”

 

‘Pathetic’ £450,000 fine because of crypto in UK water supply

Ed Walker of Blog Preston writes the reason why Prestonians couldn’t drink their water without boiling it for a month has finally been revealed.

United Utilities has been fined after a cryptosporidium outbreak at its Franklaw treatment plants to the north of Preston,

The Drinking Water Inspectorate found the problems came from the Franklaw works using a different reservoir to source water

Rainwater running off agricultural land was able to access an underground water tank at Barnacre.

A ‘planned change in operations’ allowed the entry of the contaminated water into the treatment process.

Traces of cryptosporidium were detected in the water at Franklaw triggering a shut off of supplies for 700,000 people across Lancashire.

Supplies for many were knocked out for a month during the summer of 2015 as engineers worked to fix the issue.

At Preston Crown Court the hearing fined United Utilities £300,000 and additional costs of £150,000 were also agreed. The firm had pleaded guilty to supplying water unfit for human consumption.

United Utilities was criticised for not acting fast enough to issue the boil water warning to households and businesses.

It has since paid out £20million in compensation to customers through reduced water bills.

The fine was branded ‘pathetic’ by Preston MP Mark Hendrick.

How bad FSANZ is at risk communication (or restrained by gov’t rules): At least 5 sick from crypto linked to raw milk

Below is the official Food Standards Australia New Zealand (FSNAZ) public announcement of an outbreak of crypto that has sickened at least 5 people linked to a raw milk cow share agreement:

RAW COW’S MILK

1 litre, 2 litre, 3 litre

Date marking:   NONE

MS & HJ TYLER is conducting a recall of the above product. The product has been available for sale online and at farm gate in SA.

Problem: The recall is due to microbial (Cryptosporidium) contamination

Food safety hazard: Food products contaminated with (Cryptosporidium) may cause illness if consumed.

What to do: Any consumers concerned about their health should seek medical advice and should return the product to the place of purchase for a full refund.

Media recorded actual facts about people being sick.

You’d think government could do the same.

At least 5 sick with crypto: Raw milk from Moo View Dairy recalled by South Australian health types

There was this one time, about 1979, when me and my high school buddies fell into some tickets for Can-Am car racing, which none of us cared about.

So we stayed up all night as high school students do, and then I was the designated driver to Mosport, Ontario, a few hours away.

On the way we stopped at a truck stop off the 401 near Bowmanville, Ontario, and my friends, who were quite stoned, couldn’t stop laughing about the moo-moo cow creamer on every table.

It was pasteurized.

The stuff from Willunga Hill’s Moo View Dairy is not, and the dairy will be prohibited from selling and distributing raw cow’s milk after it was linked to at least five cases of gastroenteritis.

Brad Crouch, medical reporter at The Advertiser, writes, SA Health has taken the action under the Food Act 2001 and the South Australian Public Health Act 2011, after the sicknesses were linked to drinking unpasteurised (raw) cow’s milk.

SA Health Director of Public Health Associate Professor Kevin Buckett said the sale of raw cow’s milk for human consumption is illegal in Australia due to its high risk of contamination.

“We’ve confirmed at least five cases where people aged between three and 70 contracted gastrointestinal illness caused by the Cryptosporidium parasite after consuming raw cow’s milk products purchased from Moo View Dairy, and this number is likely to be higher,” he said.

“Luckily, these people did not require hospitalisation, but it is important to remember that raw cow’s milk products should not be consumed as they can contain harmful bacteria such as E.coli, salmonella, campylobacter, and listeria, as well as cryptosporidium.

“In June we noticed higher than expected numbers of cryptosporidiosis cases and following interviews and investigations, we identified Moo View Dairy’s raw cow’s milk as a common factor between five cases,” Assoc Prof Buckett said.

“We’ve also identified another two potential cases that implicate raw cow’s milk as the cause of illness.

And the next year, Mosport had this (and yes, that’s John (J.D.) Roberts doing some of the interviews for Much Music. He can be now found as chief White House correspondent for Fox News (gag me). Oh, and I arranged Teenage Head to play our high school in 1979.

Raw is risky.

Fall fairytale: Lawsuit filed after crypto-in-apple-cider sickened more than 100 in 2015

In Oct. 2015, fall festival revellers flocked to the Pike Country Color Drive in Pike County, Illinois, and a bunch of them were soon barfing.

Unpasteurized apple cider – a staple of the northern U.S. and Canadian fall festival circuit was blamed for causing more than 100 people to fall ill with cryptosporidiosis.

Nick Draper of My Journal Courier reports a lawsuit has now been files against several groups, including the Pike County Chamber of Commerce and the Barry Business Association.

Melissa Kinman of Quincy filed the civil action against Steven and Linda Yoder of Yoder Brothers Dairy Farm, the Pike County Chamber of Commerce and the Barry Business Association. In it, she contends the Yoders were selling and offering free samples of unpasteurized cider that was tainted with Cryptosporidium.

The outbreak sickened people ranging in age from less than 1 year old to 89 years old.

Health workers from Pike and Adams counties, the state and the Centers for Disease Control and Prevention began investigating reports of profuse or bloody diarrhea, abdominal cramping and vomiting. Tests done in December 2015 by the CDC confirmed there was cider contaminated with Cryptosporidium.

Cider was not sold at last year’s drive after officials decided to pull the product.

A list of cider and juice-related outbreaks — 84 outbreaks leading to over 3,500 illnesses going back to 1924 – is available here.

Heaven on Earth rescue farm linked to crypto outbreak

Farm sanctuaries sound nice, former Daily Show host Jon Stewart and his partner run several.

But does Jon Stewart know microbiology?

Visitors to the popular Heaven on Earth animal rescue farm in Bethlehem Township, Pennsylvania (which Stewart is not affiliated with, that I know of), have come down with a variety of stomach illnesses linked to the farm, state health officials said Friday.

“At least five laboratory-confirmed cryptosporidium infections and at least six compatible illnesses have been associated with this farm,” the state Department of Health said Friday in a health advisory.

Hundreds of people may have been exposed to infected young goats and calves in the last four or five weeks since the public was invited to help feed the animals at the 3868 Bethman Road farm just east of Route 33, the advisory noted.

The Health Department is asking that all those who became ill after visiting the farm contact the department at 877-PA-HEALTH and consult their personal doctors.

Meanwhile, Heaven on Earth Farm owner Jahjah Melhem announced Friday the farm is no longer open to the public.

“In the past four years, Heaven on Earth Farm has had the pleasure of meeting so many of you. There has been a ton of love and support that visited the property at any given time,” Melhem says on the farm’s Facebook page. “We have decided that it is in our best interest to close the farm to the public so that we can focus on the well-being of the animals.”

He said he is working with the Health Department to determine the origin of the reported sicknesses. He said he isn’t sure anyone was infected at the farm, but it is possible.

“People come every day with their kids and we never had a problem,” Melhem said. “I’m fine. I’m here every day. Three or four women are here every day and none of them are sick.”

The farm has attracted 600 people since mid-February to help Melhem with 30 baby goats he rescued to avoid their slaughter. He asked for volunteers, he said, because the goats needed bottle-feeding four times a day.

On Thursday, a Health Department researcher told him she had three or four cases of people who visited the farm becoming sick later. Since then, the department has associated additional illnesses with the farm.

Educational events encouraging human–animal interaction include the risk of zoonotic disease transmission. It is estimated that 14% of all disease in the US caused by Campylobacter spp., Cryptosporidium spp., Shiga toxin-producing Escherichia coli (STEC) O157, non-O157 STECs, Listeria monocytogenes, nontyphoidal Salmonella enterica and Yersinia enterocolitica were attributable to animal contact. This article reviews best practices for organizing events where human–animal interactions are encouraged, with the objective of lowering the risk of zoonotic disease transmission.

 

We’re all hosts on a parasitic planet: Crypto edition

This is cool: the parasite seems to deliver RNA transcripts into infected hosts cells, which may then take over parts of transcription in the host.

crypto-mouse-epi-cellCryptosporidium parvum is an important opportunistic parasite pathogen for immunocompromised individuals and a common cause of diarrhea in young children. Previous studies have identified a panel of RNA transcripts of very low protein-coding potential in C. parvum.

Using an in vitro model of human intestinal cryptosporidiosis, we report here that some of these C. parvum RNA transcripts were selectively delivered into the nuclei of host epithelial cells during C. parvum infection. Nuclear delivery of several such parasitic RNAs, including Cdg7_FLc_0990, involved heat-shock protein 70-mediated nuclear importing mechanism. Overexpression of Cdg7_FLc_0990 in intestinal epithelial cells resulted in significant changes in expression levels of specific genes, with significant overlapping with alterations in gene expression profile detected in host cells following C. parvum infection.

Our data demonstrate that C. parvum transcripts of low protein-coding potential are selectively delivered into epithelial cells during infection and may modulate gene transcription in infected host cells.

Crypto hits NSW pools

As we chill (sweat) in the sleepy haven of South Golden Beach in New South Wales for a brief Christmas break, health authorities report Cryptosporidium has sickened at least 200 people in December and are warning people with diarrhea to stay out of shared pools.

sorenne-south-golden-beach-16The Sydney Morning Herald reports almost half of the cases were in children under 10-years-old. 

Health authorities have issued the warning urging people to stay out of shared swimming pools and water parks.

The biggest outbreak of cryptosporidiois was recorded in Sydney in 1998, when there were more than 1,000 confirmed cases.

Sydney was forced to boil its drinking water because it was found to be infected with the pathogens cryptosporidium and giardia.

Crypto: My big barfing Greek wedding

Amanda Devlin of The Sun reports a  bride and groom who thought they were suffering from wedding day jitters had actually been struck down by a gastric illness – as well as half of their guests.

big-fat-greek-weddingGemma Tepper, 32, her partner, Lee, 36, say their big day was ruined by the outbreak of Cryptosporidium – a respiratory and gastic illness – at their hotel on the Greek island of Zante.

Now 60 holidaymakers have hired international personal injury lawyers, Irwin Mitchell, to investigate the outbreak.

Gemma, a transport administration clerk, who was staying at the Marelen Hotel with her husband-to-be and their daughter Sylvie said: “When we both started suffering illness on our wedding day we just put it down to being nervous, but we quickly realised it was a lot more than that when the symptoms continued for the next few days.”

The symptoms persisted and both Gemma and Lee, from Pontefract, West Yorks., were forced to time off work when they returned home.

Tests confirmed Gemma was suffering from Cryptosporidium.
