Why a neurotoxin is closing crab season in California

State officials have closed both recreational and commercial fishing for Dungeness and rock crab on the California coast north of Santa Barbara to the Oregon border, due to a large algae bloom that’s making the crab unsafe for consumption.

California's Dungeness crabsThe bloom, created by an organism called Pseudo-nitzschia, produces a neurotoxin called domoic acid that can build up in marine life. It causes vomiting, diarrhea and cramping in humans — and even death, in severe cases.

California’s Dungeness crabs are shipped across the U.S. and internationally, and the $60 million fishery is considered vital to the region’s small fishermen. Both the commercial and recreational fishery will open as soon as test samples show the crab is safe.

Clarissa Anderson, a research scientist at the Institute of Marine Sciences at the University of California, Santa Cruz, told NPR this bloom has been unprecedented in its extent and its persistence. It started in May and continued on to September.

The warm temperatures all along the North Pacific and off the West Coast are contributing to the persistence of this bloom and are allowing it to stay in the surface waters. We’re now starting to see that subside a little bit as we go into fall.

We know from weekly sampling that domoic acid levels, at least in the surface waters, have been coming down for the last two months. And they’re pretty low now.

The issue with the crabs is that toxin can persist in the sediments. And those crabs are feeding on all kinds of crustaceans and shrimp along the bottom. And so the crabs are bio-accumulating it in their flesh.

E. coli and Salmonella in tomatoes

Salmonella serovars have been associated with the majority of foodborne illness outbreaks involving tomatoes, and E. coli O157:H7 has caused outbreaks involving other fresh produce.

tomatoContamination by both pathogens has been thought to originate from all points of the growing and distribution process. To determine if Salmonella serovar Typhimurium and E. coli O157:H7 could move to the mature tomato fruit of different tomato cultivars following contamination, three different contamination scenarios (seed, leaf, and soil) were examined. Following contamination, each cultivar appeared to respond differently to the presence of the pathogens, with most producing few fruit and having overall poor health.

The Micro-Tom cultivar, however, produced relatively more fruit and E. coli O157:H7 was detected in the ripe tomatoes for both the seed- and leaf- contaminated plants, but not following soil contamination. The Roma cultivar produced fewer fruit, but was the only cultivar in which E. coli O157:H7 was detected via all three routes of contamination. Only two of the five cultivars produced tomatoes following seed-, leaf-, and soil- contamination with Salmonella Typhimurium, and no Salmonella was found in any of the tomatoes. Together these results show that different tomato cultivars respond differently to the presence of a human pathogen, and for E. coli O157:H7, in particular, tomato plants that are either contaminated as seeds or have a natural opening or a wound, that allows bacteria to enter the leaves can result in plants that have the potential to produce tomatoes that harbor internalized pathogenic bacteria.

Cost of Salmonella

Hospitalized salmonellosis patients with concurrent chronic conditions may be at increased risk for adverse outcomes, increasing the costs associated with hospitalization. Identifying important modifiable risk factors for this predominantly foodborne illness may assist hospitals, physicians, and public health authorities to improve management of these patients.

salm.hospital.nov.15The objectives of this study were to (1) quantify the burden of salmonellosis hospitalizations in the United States, (2) describe hospitalization characteristics among salmonellosis patients with concurrent chronic conditions, and (3) examine the relationships between salmonellosis and comorbidities by four hospital-related outcomes.

A retrospective analysis of salmonellosis discharges was conducted using the Agency for Healthcare Research and Quality’s Nationwide Inpatient Sample for 2011. A supplemental trend analysis was performed for the period 2000–2011. Hospitalization characteristics were examined using multivariable regression modeling, with a focus on four outcome measures: in-hospital death, total amount billed by hospitals for services, length of stay, and disease severity.

In 2011, there were 11,032 total salmonellosis diagnoses; 7496 were listed as the primary diagnosis, with 86 deaths (case-fatality rate = 1.2%). Multivariable regression analyses revealed a greater number of chronic conditions (≥4) among salmonellosis patients was associated with higher mean total amount billed by hospitals for services, longer length of stay, and greater disease severity (p ≤ 0.05). From 2000 to 2011, hospital discharges for salmonellosis increased by 27.2%, and the mean total amount billed by hospitals increased nearly threefold: $9,777 (2000) to $29,690 (2011).

Observed increases in hospitalizations indicate the burden of salmonellosis remains substantial in the United States. The positive association between increased number of chronic conditions and the four hospital-related outcomes affirms the need for continual healthcare and public health investments to prevent and control this disease in vulnerable groups.

It’s not home-made that’s the risk: Mayo on food poisoning risk list

This isn’t news: Home-made mayonnaise and aioli might taste better (no, they don’t) but experts are urging cooks to take extra care with raw egg dishes to avoid food poisoning.

raw.eggsAnd many Australians are unaware that cooked rice and alfalfa sprouts, usually eaten raw, also can be a poisoning risk.

A national survey, conducted before the start of Australian Food Safety Week on Sunday, found some people couldn’t correctly identify foods often linked to food poisoning outbreaks when not handled or cooked correctly

They include chicken, minced meat and seafood, says Food Safety Information Council chair Rachelle Williams.

The increase in salmonella outbreaks in recent years is linked to raw or minimally cooked egg dishes such as hand made aioli and mayonnaise.

If the risk of Salmonella in an egg in 1-in-20,000, what does that risk become when 100 eggs are pooled together to make mayo or aoili? 1-in-200.

Any restaurant should use pasteurized eggs.

This is news: Today, in 1971, the first record I ever bought was released: Led Zepplin IV. I remember arriving at my grandparents’ house in Cookstown, Ontario (that’s in Canada) and putting it on. They said it was a terrible noise. I loved it.

Safer food saves lives

That’s the view from the U.S. Centers for Disease Control and Prevention, and I agree.

powell.food.safety.aug.15Contaminated food sent to several states can make people sick with the same germ. These multistate outbreaks cause serious illness, and more of these outbreaks are being found. Multistate outbreaks caused 56% of deaths in all reported foodborne outbreaks, although they accounted for just 3% of all such outbreaks from 2010 to 2014. Foods that cause multistate outbreaks are contaminated before they reach a restaurant or home kitchen. Investigating these outbreaks often reveals problems on the farm, in processing or in distribution that resulted in contaminated food. Lessons learned from these outbreaks are helping make food safer. To protect the public’s health, government at all levels and food industries need to work together to stop outbreaks and keep them from happening in the first place.

Food industries can:

Keep records to trace foods from source to destination.

Use store loyalty card and distribution records to help investigators identify what made people sick.

Recall products linked to an outbreak and notify customers.

Choose only suppliers that use food safety best practices.

Share proven food safety solutions with others in industry.

Make food safety a core part of company culture.

Meet or exceed new food safety laws and regulations.

Problem

what.is.safe.food.09Multistate foodborne outbreaks are serious and hard to solve.

Multistate outbreaks can be hard to detect.

Contaminated food grown or produced in a single place can wind up in kitchens across America.

People in many states may get sick from a contaminated food, making it difficult to spot the outbreak.

Detecting that an outbreak is happening requires specialized testing of germs in laboratories across the country.

Multistate outbreaks can be hard to investigate.

Investigators depend on sick people to remember what they ate several weeks earlier.

If the problem is a contaminated ingredient, people may unknowingly eat it in many different foods.

Unexpected foods have been linked to recent multistate outbreaks, such as caramel apples and chia powder.

Contaminated food can be hard to trace to the source.

Companies may not have complete records of the source or destination of foods.

food.that.doesn't.make.you.barf.09Imported food can be even harder to trace to its source, and imports to the US are increasing.

Many different farms may produce the beef in a single burger or the fresh vegetables sold in a single crate.

Innovative methods are helping detect and solve more multistate outbreaks.

New DNA sequencing technology is improving public health’s ability to link germs found in sick people and in contaminated foods.

Information technology is helping investigators in many places work together.

Efforts by food industries are helping trace contaminated foods to their source.

What Can Be Done

The Federal government is

Implementing improved food safety laws and regulations.

Working with state and local health departments to use better methods, including DNA sequencing, to find, investigate and quickly stop multistate foodborne outbreaks.

Helping state and local health departments improve food safety inspections and guidelines.

State and local public health agencies can

Encourage clinical laboratories to quickly submit germs from sick people to the public health laboratory for advanced testing.

Test the germs from sick people quickly to find if others got sick from the same germ.

Interview sick people promptly about what they ate, using standard questions.

Family guy barfTest suspect foods, if available.

Participate in national networks to share improved methods for investigating multistate outbreaks.

Encourage industry actions that focus on preventing foodborne disease.

Health care providers can

Submit germs from sick people quickly to public health laboratories for advanced testing.

Report suspected outbreaks rapidly to the local or state health department.

Inform patients or caretakers of those in high-risk groups that they have an increased risk for food poisoning. These include pregnant women, adults over 65 years, children under 5, and people with weakened immune systems. Steps to prevent food poisoning can be found on: www.foodsafety.gov

Food industries can

Keep records to trace foods from source to destination.

Use store loyalty card and distribution records to help investigators identify what made people sick.

Recall products linked to an outbreak and notify customers.

Choose only suppliers that use food safety best practices.

Share proven food safety solutions with others in industry.

Make food safety a core part of company culture.

Meet or exceed new food safety laws and regulations.

Everyone can

Check for food recalls and information about how to handle and prepare food safely on: www.foodsafety.gov

food.safety.stickerTake action if you think you have a foodborne sickness:

Talk to your health care provider.

Write down what you ate in the week before you started to get sick.

Report your sickness to the health department if you think you are part of an outbreak.

Assist public health investigators by answering questions about your sickness.

Consider getting a loyalty card where you shop. If there is a recall, the store can use the card to notify you.

‘There’s a poop in my burger’ – 16 of worst prank 999 calls to Cambridgeshire police amid sharp rise

Sorenne said the other day, the emergency number in Spain is 112.

sorenne.science.fair.aug.15We checked it out and she was right.

She said someone spoke in her grade 1 class about telephones.

We emphasized that the emergency number in Australia is 000.

In North America its 911, and apparently in the UK it’s 999.

A child asking for toilet roll and a report of a “poop in my burger” are among a tripling in the number of hoax 999 calls to Cambridgeshire police prompting a stark warning.

Valuable police time is being taken up by hoax and malicious callers reported fake crimes and emergencies.

A total of 366 calls deemed “inappropriate” were made to the force last year up from 109 the previous year and from January to October this year a total of 259 of the calls have been made.

Figures released using freedom of information laws also show that between August 2010 to July 2011 a total of 590 calls were made to the force that were deemed a “hoax”.

The number increased in the same period the following year to 604 and fell to 587 from August 2012 to July 2013. And the total number of officers deployed to the calls over the three years was 1,074.

The number of crimes linked to the hundreds of hoax calls was 17.

A police spokeswoman said: “The force has seen a rise in the number of hoax calls for service in the last couple of years.

“When a call for service comes in we have a duty to take that report seriously, and by wasting police time on dealing with fictitious calls people are seriously jeopardising the safety of those in genuine need of police help.”

Cambridgeshire police has released a list of hoax calls.

  A youth called, saying ‘your mum’ a couple of times, and then hung up

  Child called saying a robber had stolen his ‘di*k’, laughed, then hung up

  Fake call about an ‘orange glow’ coming from a house – regular hoax caller about fires as ‘likes seeing firefighters’ turn up

  Child asked for a toilet roll and then hung up

  Drunk person telling us they were off to get a kebab

  Child wanting to order a pizza

  Child saying their friend has been kidnapped and killed, laughing, swearing and hung up

  Fake reports of break ins

  Claims that a school was on fire

  Man saying ‘yeah, me and my girlfriend are hard core’ then hung up

  Woman reporting in hospital and nurses have taken her cigarettes off her (not mental health related)

  ‘I meant to call my friend’

  ‘There is a poop in my burger’

  ‘F**k you’

  Neighbour is killing my chickens

  Girl claiming to have been beaten up and was bleeding from ‘everywhere’ when we said we could she her on CCTV she hung up.

 

Food fraud nothing new: But we will survive

Historian Madeleine Ferrieres, until recently Professor of Modern History at the University of Avignon and the author of my favorite food book, 2002’s Mad Cow, Sacred Cow, said in a recent interview, “we still live with the illusion of modernity, with the false idea that what happens to us is new and unbearable. These are not risks that have arisen, but our consumer behavior has changed.”


What’s new is better tools to detect fraud, which also presents an opportunity: those who use the real deal should be able to prove it through DNA testing and brag about it.

The days of faith-based food safety are coming to a protracted close.

As Ferrieres wrote in her book,

“All human beings before us questioned the contents of their plates. … And we are often too blinded by this amnesia to view our presents food situation clearly. This amnesia is very convenient. It allows us to reinvent the past and construct a complaisant, retrospective mythology.”

I’ve quoted those words before, but increasingly find myself reinventing the past.

That’s OK, just sorta boring, so I coach and play hockey.

CBC’s (that’s the Canadian Broadcasting Corporation, and it’s in Canada) Marketplace, which has always had a flair for the dramatic, broadcast an episode tonight about labeling, mis-labeling, and food fraud.

They interviewed me about 2 am my time today, probably as a follow-up; I tried to shift to a broader discussion, they were more interested in gotcha-style; bottom line, all food purchases are faith-based, no matter how well you think you know a farmer, and food fraud has been going on as long as people have sold food.

Supermarket workers are speaking out to CBC’s Marketplace about how stores tamper with best-before dates and how it can make food unsafe.

For five years, Mohammad Saffari has worked as a bakery clerk at a Loblaws store in Montreal. He says he was told to change best-before dates on fresh or frozen bakery items such as cheesecakes, muffins and pastries that were weeks or months past the best-before date.

Saffari says he was told to take cheesecakes that had passed their best-before dates and add toppings, so they would appear fresh.

He says cakes were then given a new best-before date and put back on the shelves for sale.

“I decorate it and I’m selling expired stuff for $13.99,” he says. “I won’t eat this cheesecake myself. But I sell it to you.”

‘You think other stores don’t do it?’

Saffari approached Marketplace after he became frustrated with being asked to change dates. “I couldn’t take it anymore,” he says. “I was on sick leave for three to four months because of the pressure; because what you’re doing you’re not proud of and you’re forced to do it.”

After speaking up about this on a number of occasions, Saffari decided to secretly record a conversation with his supervisor where he asks about the practice. He shared the recording with Marketplace.

“Every store does the same f—ing thing. You think other stores don’t do it?” the supervisor says on tape.

“Everyone f—s with the dates, Mo. Because at the end of the year, the managers, their bonus, you understand?”

In an email, Johanne Héroux, a senior director at Loblaws, told Marketplace:

“As a company, we are fully committed to upholding the highest standards in terms of product quality and safety. We have strict protocols in place to ensure their application across all our stores and departments.

“As for the store-specific allegations brought to our attention and in accordance with our zero tolerance policy regarding actions that jeopardize the safety and quality of our products, an investigation was undertaken immediately. Necessary actions will be taken upon completion of the ongoing investigation.”

Problems industry-wide

But Saffari is only one of a number of former and current supermarket employees who spoke out about how supermarkets change best-before dates.

Marketplace heard from people who have worked in the bakery, meat and produce departments of a number of different grocery stores, both chains and independent. They described a number of tricks that supermarkets employ to make food appear fresh.

These tactics include grinding old meat with fresher meat, marinating old meat in sauces that mask the smell, cutting mould off fruit and vegetables for party trays, and cutting cakes in half to facilitate a faster sale after the best-before has passed.

One insider also says his store took meat that had gone brown from sitting out, and dipped it in blood to make it look redder. Others said they would take mouldy fruit off custard tarts, replace it and glaze it to make it look fresh.

In each of these cases, food was put out with new best-before dates that significantly extended the shelf life.

Food treated this way can harbour microbes that can make you sick, says Keith Warriner, a microbiologist at the University of Guelph.

Best-before dates aren’t a guarantee that food is safe to eat. Other factors, such as the way food is stored, can make a big difference.

For dry food, such as cookies, crackers and pasta, best-before dates are a guarantee of freshness and flavour, and don’t mean that food past that date is unsafe to eat.

So how do you know that the food you’re buying is fresh? Employees recommend buying meat from the back of the shelf, and avoiding pre-marinated or cut foods. They also suggest buying whole cakes, pies and tarts.

Restaurant owner blames homeless restroom users for outbreak

There’s a lot of amateur epidemiology going on this week. The latest comes from the owner of San Jose’s Mariscos San Juan #3, which reopened yesterday after being linked to 182 illnesses including 12 hospitalizations.

According to ABC 7, owner Segio Cruz says that homeless individuals using his restroom may have introduced the pathogen. Public health folks believe it was a food handler.1052002_630x354

“This is first time this happened in my store, I opened my store in 2000,” said Segio Cruz, the restaurant owner.

Cruz owns three restaurants. He says since the shigella outbreak, business has dropped off 70 percent. He says even more damaging is the negative reputation generated by the incident, which he feels his restaurant does not deserve. “You can get sick in your house, your office, anywhere,” insists Cruz.

Cruz said homeless people often use the bathroom inside his restaurant and that perhaps could be another contributing factor. But again, there is still no definitive answers as to what caused this massive, and now mysterious, outbreak.

If his theory is correct, how did the Shigella get from the restroom to the food?
