Portland to flush 38M gallon reservoir after teen uses it as a toilet

Portland will dispose of 38 million gallons of treated reservoir water after learning that a 19-year-old man urinated into it, even though urine-tainted drinking water is apparently not much of a health risk. 

ReservoirdogWater Bureau Administrator David Shaff said that animals urinate into the reservoir often and that there’s no real problem with that, but this is different because it (naturally) makes everyone feel super weird — or, as he put it, ”I could be wrong on that, but the reality is our customers don’t anticipate drinking water that’s been contaminated by some yahoo who decided to pee into a reservoir.”

The perp was seen peeing through an iron fence into Mount Tabor Reservoir No. 5 around 1 a.m. by security cameras and has been cited for public urination. He was accompanied by two others, ages 18 and 19, who tried (only one succeeded) to scale the fence surrounding the reservoir. All three have been given citations for trespassing. 

In describing the footage, Shaff said that there’s “really no doubt” what he’s doing. “When you see the video, he’s leaning right up because he has to get his little wee wee right up to the iron bars.”

Is it safe to keep a pig’s head with baked goods? Judge reserves decision on New Zealand bakery

The Bulls Bakery could be closed down because of problems with food safety, including a pig’s head kept with baked goods.

In Wanganui District Court on April 11, Judge David Cameron heard the Rangitikei District Council’s case for closing the High St business run by Santhya Sun.

pig.headJudge Cameron reserved his judgment until this week.

However, Mr Sun said he had tried hard to remedy problems and the council was unfairly targeting him.

Over the past year an inspector found mould growing on meat, rice and a tin of syrup, uncovered food, cooked and uncooked found placed together and a pig’s head from a home kill in the freezer with loose cakes like doughnuts and eclairs. Other problems included a pastry flan base uncovered with a plate of mince left on top, a mincer with old encrusted meat on it, fly spotting, and a sick baby playing with kitchen implements.

The council ordered the shop closed in December 2013 because of the unsafe food practices, but the owner defied the order and reopened it.

In January council did not renew Mr Sun’s registration and gave chief executive Ross McNeill the go-ahead to prosecute him.

Salmonella, staph, poop on sushi that sickened 220 in Mexico

Salmonella, fecal waste and Staphylococcus aureus were the bacteria that caused food poisoning in 36 customers three branches of Qué Rollo Sushi (Sushi Roll) and sickened up to 220.

sushi.vomit.apr.12Sergio Olvera Alba, director of Epidemiology, Ministry of Health, revealed the results of laboratory outbreak sushi, then matched the isolates with human samples.

8 dead, 26 sickened in Listeria outbreak linked to Quargel cheese in Austria; genomic sequencing

A large listeriosis outbreak occurred in Austria, Germany and the Czech Republic in 2009 and 2010. The outbreak was traced back to a traditional Austrian curd cheese called Quargel which was contaminated with two distinct serovar 1/2a Listeria monocytogenes strains (QOC1 and QOC2).

Quargel_cheeseQuargel is an acid curd cheese with a red smear made from skimmed pasteurized milk. Some recalled Quargel lots were highly contaminated with up to 106–108 colony forming units (CFU) of L. monocytogenes per gram of cheese.

From June 2009 to January 2010 Quargel outbreak clone 1 (hereafter: QOC1) was the cause of 14 cases, including 5 with a fatal outcome, while between December 2009 and February 2010, clone 2 (hereafter: QOC2) accounted for 20 cases, which resulted in 3 fatalities. No maternal or neonatal case had been reported. The median age of the cases was 72 years (range 57 to 89) and 76% of the patients were male. Of the 34 patients, 25 were Austrian, 8 were German and one was from the Czech Republic.

Rychli et al. report we sequenced and analysed the genomes of both outbreak strains in order to investigate the extent of genetic diversity between the two strains belonging to MLST sequence types 398 (QOC2) and 403 (QOC1). Both genomes are highly similar, but also display distinct properties: The QOC1 genome is approximately 74 kbp larger than the QOC2 genome. In addition, the strains harbour 93 (QOC1) and 45 (QOC2) genes encoding strain-specific proteins. A 21 kbp region showing highest similarity to plasmid pLMIV encoding three putative internalins is integrated in the QOC1 genome. In contrast to QOC1, strain QOC2 harbours a vip homologue, which encodes a LPXTG surface protein involved in cell invasion. In accordance, in vitro virulence assays revealed distinct differences in invasion efficiency and intracellular proliferation within different cell types. The higher virulence potential of QOC1 in non-phagocytic cells may be explained by the presence of additional internalins in the pLMIV-like region, whereas the higher invasion capability of QOC2 into phagocytic cells may be due to the presence of a vip homologue. In addition, both strains show differences in stress-related gene content. Strain QOC1 encodes a so-called stress survival islet 1, whereas strain QOC2 harbours a homologue of the uncharacterized LMOf2365_0481 gene. Consistently, QOC1 shows higher resistance to acidic, alkaline and gastric stress. In conclusion, our results show that strain QOC1 and QOC2 are distinct and did not recently evolve from a common ancestor.

104 sickened: increase in Vibrio parahaemolyticus infections associated with consumption of Atlantic coast shellfish — 2013

I don’t eat raw oysters. This is why.

The U.S. Centers for Disease Control reports Vibrio parahaemolyticus (Vp) is found naturally in coastal saltwater. In the United States, Vp causes an estimated 35,000 domestically acquired foodborne infections annually (1), of which most are attributable to consumption of raw or undercooked shellfish. Illness typically consists of mild to moderate Raw oystersgastroenteritis, although severe infection can occur. Demographic, clinical, and exposure information (including traceback information on implicated seafood) for all laboratory-confirmed illnesses are reported by state health departments to CDC through the Cholera and Other Vibrio Surveillance system. Vp isolates are distinguished by serotyping (>90 serotypes have been described) and by pulsed-field gel electrophoresis (PFGE).

Vp serotypes O4:K12 and O4:K(unknown) comprise the Pacific Northwest (PNW) strain and, within the United States, had not been associated with shellfish outside the Pacific Northwest before 2012. During May–July 2012, Vp of the PNW strain associated with shellfish from Oyster Bay Harbor in New York caused an outbreak of 28 illnesses in nine states. Simultaneously, Vp of the PNW strain caused an outbreak of illnesses on a cruise ship docked on the Atlantic Coast of Spain; illness was associated with cooked seafood cooled with ice made from untreated local seawater. All Vp isolates from ill persons in the U.S. and Spanish outbreaks that were further subtyped were indistinguishable by PFGE (2).

In 2013, this same indistinguishable strain was traced from shellfish consumed by ill persons to a larger area of the U.S. Atlantic Coast, causing illness in 104 persons from 13 states during May–September (Figure). The median age of patients was 51 years (range = 22–85 years); 62% were male. Six (6%) patients were hospitalized; none died. Multiple outbreaks appeared to be occurring, accounting for many of these illnesses. Illness was associated with consumption of raw shellfish and seafood traceback was reported for 59 (57%) illnesses. Of these illnesses, 51 (86%) involved seafood that could be definitively traced to a single harvest area. The implicated harvest areas were located in Connecticut (20 illnesses), Massachusetts (15), New York (10), Virginia (four), Maine (one), and Washington (one). The remaining eight illnesses with traceback information involved seafood that could not be definitively traced to a single harvest area (locations reported included harvest areas of the Atlantic Coast of the United States and Canada). In response to the illnesses, four Atlantic Coast states closed implicated harvest areas; two issued shellfish recalls (3). The number of foodborne Vp cases in the United States traced to Atlantic Coast shellfish was threefold greater in 2012 and 2013 compared with the annual average number reported during 2007–2011.

This PNW strain is possibly becoming endemic in an expanding area of the Atlantic Ocean. The mechanisms for this introduction are not known. During the 2014 Vibrio season, beginning in the spring, clinicians, health departments, and fisheries departments should be prepared for the possibility of shellfish-associated diarrheal illness caused by this strain SUN0705N-Oyster7again. Appropriate actions, such as quick closure of implicated harvest areas, will help prevent additional illnesses. The Interstate Shellfish Sanitation Conference maintains a list of shellfish harvest area closures and recalls.* Clinicians seeking an etiology of diarrhea in a patient who has recently consumed raw or undercooked shellfish should notify the microbiology laboratory that Vp is suspected; the use of special culture media (thiosulfate citrate bile salts sucrose) facilitates identification of Vibrio species. Consumers can reduce their risk for Vp infection by avoiding eating raw or undercooked shellfish, especially oysters and clams.†

27 sick with Yersinia and Campylobacter from raw milk in Finland

The first results from milk samples at a farm in Askola, Finland taken April 7 revealed Yersinia pseudotuberculosis and Campylobacter jejuni.

The number of people who drank milk from Uljaan tilamaito and experienced symptoms has still increased in Porvoo and in the neighboring municipalities (Askola, Lovisa, Borgnäs colbert.raw.milkand Sipoo). There are now 19 confirmed cases of Yersinia. Campylobakterier have so far been isolated from a total of eight people. Investigations are still ongoing for about twenty people.

Uljaan tilamaito pulled away all unpasteurized milk from the shops in early April.

Hey kids, the snails are back: CDC releases 2013 FoodNet data

That’s the tagline from a Far Side cartoon and what immediately came to mind upon reading yet again that reductions in foodborne illness were stagnant for 2013.

There were successes, failures and shifting profiles of what foods lead to foodborne illness, because whatever Americans choose to eat, under whatever production system, some smart bug is going to figure out how to flourish.

And the FoodNet data remains the best and most publicly available surveillance data in the world; that’s right, best in the world.

The Foodborne Diseases Active Surveillance Network (FoodNet) monitors the incidence of laboratory-confirmed infections caused by nine pathogens transmitted commonly through food in 10 U.S. sites, covering approximately 15% of the U.S. population. This report summarizes preliminary 2013 data and describes trends since 2006. In 2013, a total of 19,056 infections, 4,200 hospitalizations, and 80 deaths were reported. For most infections, incidence was well above national Healthy People 2020 incidence targets and highest among children aged <5 years. Compared with 2010–2012, the estimated incidence of infection in 2013 was lower for Salmonella, higher for Vibrio, and unchanged overall. Since 2006–2008, the overall incidence has not changed significantly. More needs to be done.

Yes, more needs to be done. Part of that involves abandoning archaic communications and invoking current, compelling and credible food safety messages using a variety of media, at the places where people make food decisions – whether it’s the local market or the megalomart.

Norovirus outbreak hits Florida school

Over the past couple of days I drove the family from sunny and somewhat warm Raleigh, NC to the frigid tundra of Southern Ontario. I knew things would be bad when it started snowing as we passed through Maryland – in mid-April.

One of the consequences of a long cold winter is an extended norovirus season (the virus is more stable in cold weather). Norovirus-at-school

Even in Florida.

According to local10, a Broward County, FL school is dealing with a norovirus outbreak – and some folks seem to think drinking from water fountains is a risk factor.

A contagious stomach flu-like virus is making an unusually high number of students at Boulevard Heights Elementary School in Hollywood sick.

“Been a lot of children in our school that are sick,” said student Taylor Frangesh.

“He was nauseated when he came home,” Bianca Hampton said of her son. “He told me he drank from the water fountain, so he was a little nauseated and he had a little fever.”

With the high number of students getting sick, the virus has made its way into some of their homes.

“He got sick, the brother, the sister and me — the whole family,” said Melissa Prado.

Broward County Public Schools released a statement saying the district is working with the health department over gastric concerns that were being experienced by an unusually high number of students. School officials were cleaning and sanitizing classrooms, common areas and the playground.

“They said that the water was causing it and not to drink from the water fountains and if you didn’t bring your own bottled water you still couldn’t drink from the water fountain,” said Frangesh. “They put garbage bags over the water fountains.” 

Antibacterial soaps can reduce risk of foodborne illness

Friend of the blog Don Schaffner has published some new research that shows  the use of antibacterial soaps can reduce the spread of harmful bacteria – that often leads to foodborne illness – more effectively than using non-antibacterial soaps.

The research, published in the peer-reviewed Journal of Food Protection (Vol. 77, No. 4, 2014, pp. 574-582), used new laboratory data, together with simulation techniques, to compare the ability of non-antibacterial and antibacterial products to reduce the risk of the infectious disease shigellosis, which is often spread during food preparation.

antibacterial.soapLead researcher Donald Schaffner of Rutgers University’s Department of Food Science says the data show that the use of three antibacterial wash products result in a statistically significant reduction in the presence of Shigella (the bacterium that causes shigellosis) compared to the use of the non-antibacterial soaps.

“This exciting research blends quantitative microbial risk assessments with an impressive set of laboratory data to show that antibacterial treatments are more effective than non-antibacterial treatments in reducing disease,” said Dr. Schaffner.

In the study, 163 subjects were used to compare two non-antibacterial products and three antibacterial products, with a study design intended to simulate food handling. The participants’ hands were exposed to Shigella and then treated with one of the five products before handling food melon balls. The resulting levels of Shigella on the food were then measured.

The levels of Shigella were then used to predict the outcome from an event in which 100 people would be exposed to Shigella from melon balls that had been handled by food workers with Shigella on their hands.

The data show all three antibacterial treatments significantly lowered the concentration of Shigella compared to the non-antibacterial treatments. Based on this model, the paper predicted that by washing with the antibacterial treatments, the number of illnesses could be reduced tenfold.

“This research provides strong evidence that antibacterial soaps are significantly more effective than non-antibacterial soaps in reducing Shigella on the hands and its subsequent transfer to ready-to-eat foods,” the authors write.

The American Cleaning Institute (www.cleaninginstitute.org) and the Personal Care Products Council (www.personalcarecouncil.org) provided funding for the research as part of the groups’ ongoing commitment to product and scientific stewardship to affirm the safety and benefits of these products.
