USA – Cyclospora Updates – Salad Mix the Source

Food Poisoning BulletinEurofins Food Testing UK

Taylor Farms de Mexico food service salad served at Olive Garden and Red Lobster restaurants is the source of the Cyclospora outbreak that sickened at least 232 people in Iowa and Nebraska. Health officials from those states announced July 30 that a salad mix containing iceberg and romaine lettuces, carrots and red cabbage was the source of the illnesses, but did not release the name of the company that produced it as the tainted salad was no longer in circulation in those states.

Food Poisoning Bulletin

Cyclospora illnesses that have sickened more than 400 people across the country in an outbreak have been linked to packaged salad greens. These products have been linked to many outbreaks over the years.

In fact, a study conducted by the Centers for Disease Control and Prevention (CDC), released in January of this year, said that leafy greens were responsible for the majority of foodborne illness outbreaks from 1998 to 2008. Last year, the seventh largest food poisoning outbreak in the U.S. was linked to a spinach and spring mix.

FDA Investigation

On July 30, 2013, the states of Iowa1 disclaimer icon 2 and Nebraska3 announced that their analysis indicated that the outbreak in those states was linked to a salad mix. In follow-up to that announcement, the U.S. Food and Drug Administration is providing an update on its investigation.

The FDA traceback investigation has confirmed that the salad mix identified by Iowa and Nebraska as being linked to the outbreak of cyclosporiasis in those states was supplied to restaurants in those states by Taylor Farms de Mexico, S. de R.L. de C.V., a processor of foodservice salads.    The FDA traceback investigation found  that illness clusters at restaurants were traced to a common supplier,  Taylor Farms de Mexico, S. de R.L. de C.V. The restaurants in Iowa and Nebraska include Olive Garden and Red Lobster, both of which are owned by Darden Restaurants.

FDA’s investigation has not implicated consumer packages sold in grocery stores.

 

USA – Cyclospora Outbreak Still Going Up

Food Poisoning Journal

  • As of July 29, 2013 (5pm EDT), CDC has been notified of 372 cases of Cyclospora infection from the following 16 health departments: Iowa, Texas, Nebraska, Florida, Wisconsin, Illinois, New York City, Georgia, Missouri, Arkansas, Connecticut, Kansas, Minnesota, New Jersey, New York, and Ohio.
  • Most of the illness onset dates have ranged from mid-June through early July.
  • At least 21 persons reportedly have been hospitalized in three states

Lincoln – Prepackaged salad mix is the source of the state’s cyclospora outbreak which has sickened 78 Nebraskans since mid-June according to the Nebraska Department of Health and Human Services. Cyclospora is a rare parasite that causes a lengthy gastrointestinal illness.

“Our goal is to protect Nebraskans, pinpoint the source of the illness and make sure the risk is eliminated,” said Dr. Joseph Acierno, Chief Medical Officer and Director of Public Health for DHHS. “Our investigation implicated prepackaged, prewashed, salad mix as the cause of this outbreak.”

DHHS’ investigation also shows the salad mix which includes iceberg and romaine lettuce along with red cabbage and carrots came through national distribution channels. Locally grown produce is not part of this outbreak.

DHHS and local health departments are currently working with the U.S. Food and Drug Administration to identify exactly where the contamination came from along the food production chain and where the product was distributed. Nebraska public health officials believe the bulk of the contaminated salad mix already worked its way through the system due to limited shelf life.

Fresh vegetables and fruit are usually associated with cyclospora outbreaks. People become sick when they consume food contaminated with the parasite. Washing fruits and vegetables is always recommended but it can be difficult to wash cyclospora off all types of produce.

 

 

USA – More Cyclospora and Hepatitis A Cases

Food Poisoning Bulletin

The Cyclospora outbreak that has been reported by health departments in several midwestern states may have sickened as many as 183 people. The Iowa Department of Public Health released new information today saying their case count is up to 87. In Nebraska, 54 people are sick, and Texas has 37 cases of the parasitic disease so far this year; of those, 29 in north Texas were reported just this week.

FIVE visitors to Countryfile presenter Adam Henson’s farm in the Cotswolds and one member of staff are being treated for the intestinal infection cryptosporidium.

Public Health England (PHE) is working closely with the Health and Safety Executive, Cotswold District Council, Animal Health and Veterinary Laboratories Agency (AHVLA) and Cotswold Farm Park to investigate the outbreak at Cotswold Farm Park, Guiting Power, near Bourton-on-the-Water.

Everyone affected is recovering well at home and the farm park has put in extra measures to reduce the risk of infection to visitors over the coming bank holiday Monday.

Australia – NSW – Cryptosporidium in Swimming Pools

NSW763px-Cryptosporidium_parvum_01

NSW Health is urging people who have had diarrhoea not to swim in pools until at least two weeks after they have fully recovered following an increase in cryptosporidiosis in NSW.

There have been 484 cases of cryptosporidiosis reported to NSW Health to date this year. The highest rates of infections are in children under five,” Dr Jeremy McAnulty, Director, Health Protection, said.

This is the highest year to date figure since 2009 when there was a large outbreak with more than 1000 notified cases.

226 cases were reported in February which is a significant increase on the 5 year average of 121 cases. So far, 126 cases have been reported in March.

“Cryptosporidiosis is a diarrhoeal disease caused by a parasitic infection of the intestine. The most common symptoms include diarrhoea, stomach cramps and sometimes fever, nausea and vomiting. There is no specific treatment for the condition and symptoms may last a few weeks in some people,” Dr McAnulty said.

Among the cases, a range of possible risk factors have been reported including swimming in pools. However the outbreak has not been linked to a specific pool. In previous studies other risk factors have included contact with farm animals and drinking untreated water.

Australia- Gastroenteritis Linked to Swimming Pool Water

Courier Mail

Victoria’s chief health officer Dr Rosemary Lester said there has been a three-fold increase in gastro cases after hot weather sparked people seeking to cool off at public swimming pools.

She urged those who have had diarrhoea not to go into a swimming pool for at least 14 days after symptoms had stopped for fear of passing on the bug.

Dr Lester said the cryptosporidium gastro parasite could not be killed by normal levels of chlorination.

“Cryptosporidiosis is typically caused by swallowing contaminated water, household contact with a case and contact with farm animals,” she said.

Authorities are working with swimming pool owners to implement extra measures to kill the parasite.

Symptoms included watery diarrhoea, stomach cramps and vomiting, Dr Lester said.

Dr Lester urged sufferers to shower before swimming to avoid infecting others, with children and the elderly particularly at risk.

There were 155 Victorian cases of gastro caused by the cryptosporidium parasite last month, three times the February average of 53.

New Zealand – Cryptosporidium Outbreak?

The New Zealand Herald763px-Cryptosporidium_parvum_01

Hawke’s Bay’s water operators are checking the region’s supplies for contamination of Cryptosporidium.

Health authorities have issued a warning following the diagnosis of 45 people over the past two months.

Medical Officer of Health Dr Nicholas Jones said the health protection team is analysing information to establish the cause of the outbreak – and expect there is more than one source.

“We’ve been in touch with the water operators and they don’t think they’ve got problems at the moment, but obviously it’s something we’re going to be looking into in more detail,” said Dr Jones.

Cryptosporidium Cases – USA

The Oneida County Department of Health has announced that there have been six confirmed cases of Cryptosporidium and that the Oneida County Health Department is currently investigating the origin of the outbreak.

Officials are looking into the possibility of the outbreak stemming from the recent Farmfest event, but caution that no direct causal link has yet been determined.

Cryptosporidium is a microscopic parasite that causes the intestinal illness and that it is usually a self-limiting illness with watery diarrhoea as the most common symptom. Average incubation is one to 12 days.

Toxoplasma Research Required

Food Manufacture

More research is needed to determine how big a role food plays in the transfer of the parasitic disease toxoplasmosis to humans in the UK, according to scientists.

Toxoplasmosis has been implicated in the USA and UK as a  foodborne illness in about 50% of reported cases.

FSA – Cryptosporidium Cases

The Health Protection Agency (HPA) can confirm it is investigating a recent increase in cases of the gastrointestinal infection, cryptosporidiosis, across four regions in England – the North East, Yorkshire, West Midlands and East Midlands.

To date, 267 cases of cryptosporidiosis have been confirmed in the affected areas since 11 May 2012, compared to 73 cases across the four regions for the whole of May 2011.

Dr Stephen Morton, who is leading the investigation for the HPA, said: “It is usual to see an increase in cryptosporidiosis cases in the early summer, but, the increase is higher than we might expect so we are working with NHS partners, local Environmental Health Officers the Drinking Water Inspectorate and the Food Standards Agency to see if there is a common source of infection.
