4 dead, 101 sick; Norovirus strikes hospital in Japan

Norovirus continues to ravage Japan after four elderly patients died in an outbreak at a hospital in the western Japanese city of Kyoto.

Earlier, at least 77 contracted Norovirus after consuming bentos from a store, and over 1,000 schoolchildren were stricken after consuming norovirus.elderly womanbread that was probably contaminated by food workers.

The four victims at the hospital were in their 80s and 90s and were among 101 patients and staff members who have exhibited the virus-caused gastroenteritis symptoms of vomiting and diarrhea over the past five weeks at the hospital in Fushimi Ward of the city.

77 suffer food poisoning in Japan; 25 confirmed with Norovirus

Aomori prefectural health officials said Monday that 77 people suffered food poisoning after eating bentos bought from a store in Hachinohe. Of the 77, 25 had contracted the norovirus, officials said.

Fuji TV quoted health officials as saying the bentos in question were sold on Jan 14. The store said it sold bentos to 284 customers. Seventy-sushi-bento-express2seven people complained of nausea, vomiting and diarrhea on Jan 16, officials said. The victims ranged in age from their 20s to 70s.

The store, named Wa, has been ordered to suspended operations for five days, until Friday. 

Employees fingered in Norovirus outbreak linked to bread

A massive norovirus outbreak amongst school children in Japan has been, according to health authorities, linked to three factory staff who handled bread as part of their jobs. Japan News reports that norovirus was detected in stool samples of the three staff members – signs of the virus were not founds in an additional 16 food handlers who also submitted samples.hlebozavod-0024

The bakery is suspected to have been the cause of a mass food poisoning that affected many primary schools in the city, according to the Hamamatsu city government.
The city government announced Sunday that workers at Hofuku, a company that produced bread deemed to be the cause of the norovirus outbreak, were found to be infected with the virus.

Yoshinao Terada, chief of the city government’s living and health section, said at a press conference, “It is highly likely that persons with the virus took part in the production process leading to contamination of the bread.”

The company ordered the three workers to stay home from work and specialists began sterilizing the plant. 

Asymptomatic norovirus carriers have been linked to lots of outbreaks in the past.  It’s also possible that the individuals were ill, recovered, and still shedding viruses in their stool. My NoroCORE colleague Robert Atmar and colleagues reported in 2008 that noro could be recovered from folks infected with the virus for up to 56 days (with a median of 28 days) – long after symptoms subsided.

Regardless, there are some hygiene issues going on at Hofuku.

1000 kids sick with norovirus linked to bread in Japan

Bread maker Hofuku, which has admitted one of its products is probably responsible for causing more than 1,000 children in Hamamatsu, Shizuoka Prefecture, to suffer food poisoning, has started recalling its products from retailers, including supermarkets in Yamanashi, Shizuoka, Aichi and Okayama prefectures.

According to the Hamamatsu Municipal Government, the bread the local company produced Monday and delivered to schools Tuesday morning is likely to have been tainted sliced_breadwith the norovirus.

The municipal authorities’ inspection Thursday night detected the virus from a rest room slipper at the company’s plant, according to city and board of education officials.

The city ordered Hofuku to suspend operations.

Twenty-three workers were involved in the bread slicing and packaging process at the factory Monday when the norovirus-tainted bread was made.

300 sick from pesticide in frozen food in Japan

More than 300 people across Japan have fallen ill after eating frozen food products contaminated with pesticide.

Shoppers have reported vomiting, diarrhea and other symptoms of food poisoning after eating food produced at a plant in Gunma, north of Tokyo, according to surveys carried Maruha Nichiroout by the Asahi Shimbun and other local media.

The plant, run by a subsidiary of the nation’s largest seafood firm Maruha Nichiro Holdings, is at the centre of the nation’s latest food poisoning scandal.

Japanese police have launched an investigation into the company after it revealed last month that some of its frozen food products were tainted with malathion, an agricultural chemical often used to kill aphid in corn and rice fields.

118 sick; norovirus at Japan hotel

Tochigi prefectural health officials announced Monday that 118 guests suffered food poisoning at a hotel in Nikko City earlier this month and that traces of food-borne Norovirus strains had been detected.

According to authorities, the Kinugawa Gyoen Hotel received complaints of gastrointestinal distress from male and female guests ranging in age from two to 80 between Dec 18 and norovirus-2Dec 22. TBS quoted a hotel spokesperson as saying symptoms included vomiting and diarrhea. Among the 118, eight guests and 11 chefs and kitchen staff were discovered to have the Norovirus strain in their systems.

Health officials said no one had to be hospitalized.

According to a hotel spokesperson, the 118 afflicted guests had eaten inside the hotel restaurant, dining on a variety of menu items, ranging from sashimi dishes to hot Japanese-style curries.

TBS quoted a prefectural health official as saying that the hotel is suspected of violating food hygiene laws, and was ordered to cease activity in its restaurant and kitchen. The hotel has remained closed since Dec 26.

304 sickened; E. coli O157 outbreak associated with consumption of rice cakes in 2011 in Japan

In May 2011, an outbreak of Shiga toxin-producing Escherichia coli (STEC) O157 was reported from Yamagata Prefecture, Japan. Investigations, including a case-control study, revealed that the outbreak was linked to two varieties of rice cakes produced by a local manufacturer between 2 and 7 May. Active and passive surveillance identified 136 suspected cases, 142 confirmed cases, 26 asymptomatic cases, and 25 secondary cases. While no environmental samples taken from the manufacturing premises tested positive for STEC, other than a stool sample taken from one employee, on-site and epidemiological investigations indicated that STEC was introduced during the manufacturing process of rice cakes rather than through contamination of raw materials. This was the first reported outbreak of STEC associated with cakes and confectionery in Japan, which indicates that contamination and outbreaks of STEC can occur in any food unless proper precautions are taken.

6 dead, 99 suspected sick from E. coli O157 in pickled cabbage in Japan

Four people, including a 4-year-old girl, have been confirmed dead of food poisoning from pickled Chinese cabbage produced by a Sapporo food company.

The Yomiuri Shimbun reports another two are suspected to have died due to the cabbage.

According to the city health care center, four people have died of poisoning caused by E. coli O157 after eating pickled Chinese cabbage produced in late July by Iwai Shokuhin. Three of the four victims were women in their 80s and 100s living in elderly care facilities in the city.

Mass food poisoning occurred at elderly care facilities in and around the city, with 99 patients likely connected to the suspect cabbage.

Four-year-old girl Ayana Matsumura of Sapporo suffered symptoms from Aug. 6 and died last Saturday.

The O157 strain discovered in her body was found to be the same strain detected in the cabbage. According to information relayed to the city by her family, she is very likely to have eaten cabbage bought at a supermarket near her house.

The food firm’s president, Norio Iwai, expressed deep regret. "I feel deeply about (the incident) and will do my best to help investigations. I can only say I’m truly sorry," he said.

E. coli O157 found inside liver, not just on surface; will a raw beef liver ban in Japan work?

Japan is going to ban raw beef liver from restaurants effective July 1, 2012, but the move could be a precursor for a wider ban on equally risky – but beloved – raw foods in Japan.

In May 2011, E. coli O111 in raw beef – not liver but hamburger — killed five and sickened at least 180 in Japan.

According to the Wall Street Journal, a couple months later, the government urged businesses to show self-restraint in serving raw beef — yet 13 people were affected by raw beef-related food poisoning since July, according to the health ministry. Over 850 people have been hospitalized for food poisoning after consuming raw beef liver from 1998 through the end of 2011. About 9% of those cases were caused by E. coli contamination.

Subsequently, testing of raw meat was increased, and according to a report for the government, of the 173 cow livers tested from 16 different locations nationwide, three samples were found to be contaminated with E. coli O157 inside the meat, not just on its exterior, and five samples had exterior contaminations.

In April, a food safety panel under the Cabinet Office backed the plan to restrict serving raw beef liver. The new rules also target raw beef liver sold to households. Raw beef liver will remain on refrigerated shelves, but stores will be required to put up signs advising consumers to only eat the meat cooked.

The new ban on raw liver means restaurants will be required to cook beef liver at 63 degrees Celsius (145.4 degrees Fahrenheit) for a minimum 30 minutes, or 75 degrees Celsius for at least one minute, before serving the meat. Failure to comply could result in a ¥2 million fine as well as two years in jail.

The All Japan Meat Industry Co-operative Association has protested the panel’s deliberations, saying this could be the beginning of an endless campaign to remove other raw foods from Japanese dining tables — a particularly serious charge in a nation heavily reliant on raw foods. “If this direction continues, they could also say ‘eating raw eggs is dangerous so it will be banned.’ And following the same logic, we may no longer be able to eat sashimi because the most number of food poisoning cases comes from raw fish,” the group wrote in a letter to the health ministry in early May. More food-poisoning illnesses spring from raw fish, in large part because the volume consumed far exceeds other foods. But the ministry official said it targeted beef liver because of the enormous strength of the pathogen.

Yomiuri Shimbun reports that many livestock farmers were staggered by the ministry’s decision, which could cut their income considerably, although consumer groups praised the ban.

Hisa Anan, the chief of the secretariat of the National Liaison Committee of Consumers’ Organization, welcomed the ministry’s move.

"The ministry couldn’t eradicate food poisoning just by asking restaurants to voluntarily stop serving raw beef liver. I guess the ministry had no alternative," she said.

However, others experts have criticized the ministry’s decision.

"The ministry should encourage consumers to make their own decisions by providing them with adequate information, rather than imposing a blanket ban," said Tsutomu Sekizaki, director of the University of Tokyo’s Research Center for Food Safety.

As the Brits have repeatedly shown, cooking liver don’t work so well after numerous of outbreaks of Campylobacter in undercooked liver pate. Bans, however, seem heavy-handed. Worse is the inconsistency: why just raw beef liver instead of raw beef? It was raw hamburger that caused the E. coli O111 outbreak. Maybe something is being lost in translation, but the notice does reek of a trial balloon.

Tokyo chefs swell with anger over new blowfish laws

Blowfish chefs are upset that Japan, which just threatened to tighten regulations on serving raw meat to control disease, is proposing to loosen regs on potentially deadly blowfish.

Reuters reports that for more than six decades, dicing blowfish in Tokyo has been the preserve of a small band of strictly regulated and licensed chefs, usually in exclusive restaurants.

But new laws coming into effect from October are opening the lucrative trade to restaurants without a license, making chefs like Naohito Hashimoto see red.

"We have spent time and money in order to obtain and use the blowfish license, but with these new rules anybody can handle blowfish even without a license," said Hashimoto, a blowfish chef for some 30 years.

"They’re saying it’s now okay to serve blowfish. We licensed chefs feel this way of thinking is a bit strange."

The poison known as tetrododoxin is found in parts of the blowfish, including the liver, heart, intestines and eyes, and is so intense that a tiny amount will kill.

Every year there are reports of people dying after preparing blowfish at home.

The Tokyo Metropolitan Government says city laws covering the serving of blowfish should be changed to reflect changing times and hope that relaxing the rules will cut prices and bring Tokyo in line with the rest of the nation.

"Outside of Tokyo, the regulations for blowfish are even more relaxed and yet there are hardly any poison-related accidents," said Hironobu Kondo, an official at the city’s Food Control Department.

"There is the hope that the number of restaurants with unlicensed chefs serving blowfish will rise, and that blowfish as an ingredient will be used not only for traditional Japanese foods but also others such as Chinese and Western foods."

A full course meal of blowfish, known as fugu in Japanese, features delicacies such as blowfish tempura, slices of raw fish thin enough to see through fanned out across a plate like chrysanthemum petals, and toasted fins in cups of hot sake.

But the meal is far from cheap, as diners pay for the safety of a licensed chef. At Hashimoto’s restaurant, a meal costs at least 10,000 yen a person.

"I don’t want people to forget that you can actually die from eating blowfish," he said. "I feel the government’s awareness of this has diminished."
