California Acts to Protect Public Health: CDPH Warns Against Drinking Single Lot of Raw Milk Following Bird Flu Detection

Thanks to Helen Branswell and others for alerting me to this news release from the California Department of Public Health: California Acts to Protect Public Health: CDPH Warns Against Drinking Single Lot of Raw Milk Following Bird Flu Detection; Secures Voluntary Recall. Excerpt:

What You Need to Know: CDPH warns consumers not to drink one batch of cream top, whole raw milk from Raw Farm, LLC of Fresno County due to a detection of bird flu virus. Raw Farm, LLC issued a voluntary recall at the state’s request of the affected lot code 20241109 with a Best By date of 11/27/2024. Consumers should immediately return any remaining product to the store where it was purchased. Pasteurized milk remains safe to drink.

Sacramento –​ The California Department of Public Health (CDPH) today is warning the public to avoid consuming one batch of cream top, whole raw milk produced and packaged by Raw Farm, LLC of Fresno County due to a detection of bird flu virus in a retail sample. At the state’s request, the company has issued a voluntary recall of the affected raw milk with lot code 20241109 and Best By date of 11/27/2024 printed on the packaging.​ 

No illnesses associated with this lot of raw milk have been reported. Out of an abundance of caution, and due to the ongoing spread of bird flu in dairy cows, poultry, and sporadic human cases, consumers should not consume any of the affected raw milk. Customers should immediately return any remaining product to the retail point of purchase. CDPH is also notifying retailers to remove the affected raw milk from their shelves.​​   

The County of Santa Clara Public Health Laboratory has been testing raw milk products from retail stores as a second line of consumer protection. The county identified bird flu in one sample of raw milk purchased at a retail outlet. The testing was then verified by the California Animal Health and Food Safety Laboratory System.  

Risks Associated with Raw Milk  

Public health experts have long warned consumers against consuming raw milk or raw milk products due to elevated risks of foodborne illness. Outbreaks due to Salmonella, Listeria monocytogenes, toxin producing E. coli, Brucella, Campylobacter, and many other bacteria have all been reported related to consuming raw dairy products. Raw milk products are not pasteurized, a heating process that kills bacteria and viruses such as bird flu.   

Pasteurized milk and milk products are safe to consume because the heating process kills pathogens, including bird flu, that can cause illness.   

Drinking or accidentally inhaling raw milk containing bird flu virus may lead to illness. In addition, touching your eyes, nose, or mouth with unwashed hands after touching raw milk with bird flu virus may also lead to infection. Symptoms of bird flu infection in humans include eye redness or discharge, cough, sore throat, runny or stuffy nose, diarrhea, vomiting, muscle or body aches, headaches, fatigue, trouble breathing and fever. Anyone who has consumed these specific products, and is experiencing these symptoms, should immediately contact their health care provider or local health department. 

Cows infected with bird flu have died in five US states

Via Reuters: Exclusive: Cows infected with bird flu have died in five US states. I sincerely hope that sick cows sent to slaughter do not then enter the food chain. Excerpt:

June 6 (Reuters) - Dairy cows infected with avian flu in five U.S. states have died or been slaughtered by farmers because they did not recover, state officials and academics told Reuters.  

Reports of the deaths suggest the bird flu outbreak in cows could take a greater economic toll in the farm belt than initially thought. Farmers have long culled poultry infected by the virus, but cows cost much more to raise than chickens or turkeys. 

A U.S. Department of Agriculture spokesperson said the agency knew of a few deaths but that the vast majority of cows recover well. Reuters was not able to determine the total number of cows with bird flu that died or were killed in South Dakota, Michigan, Texas, Ohio and Colorado.  

Avian flu has infected dairy cows in more than 80 herds across 10 states since late March, according to the USDA.  

Some of the animals died of secondary infections contracted after bird flu weakened their immune systems, said state veterinarians, agriculture officials, and academics assisting in state responses to bird flu. Other cows were killed by farmers because they failed to recover from the virus.  

Cattle infected with bird flu suffer reduced milk production, digestive issues, fever, and diminished appetite, according to farmers and veterinarians.  

In South Dakota, a 1,700-cow dairy sent a dozen of the animals to slaughter after they did not recover from the virus, and killed another dozen that contracted secondary infections, said Russ Daly, a professor with South Dakota State University and veterinarian for the state extension office who spoke with the farm. 

"You get sick cows from one disease, then that creates a domino effect for other things, like routine pneumonia and digestive issues," Daly said.  

A farm in Michigan killed about 10% of its 200 infected cows after they too failed to recover from the virus, said Phil Durst, an educator with Michigan State University Extension who spoke with that farm.

Mongolia: Two dead of bubonic plague

Via Web24 News, an Infobae report: Mongolia ordered quarantine and closure of part of the border with Russia after reported deaths from bubonic plague. A lightly edited excerpt and then a comment:

Mongolia ordered entry into quarantine from the city of Tsetseg, in the western province of Khov, after two deaths were detected by bubonic plague, as reported by local health authorities. A partial closure of the border with Russia was also ordered, to avoid an outbreak that could spread beyond the country’s limits. 

The victims, whose identity was not disclosed so far, had consumed marmot meat. The disease is also known in the region as “marmot plague” 

“Specialists from the National Center for Disease Control and Prevention (NCDC) and the National Center for Disease Control and Prevention (NCDC) in Khovd and Bayan-Ulgii are working to establish a quarantine in Jargalant and Tsetseg soums," the local government said. 

“In the two confirmed cases, 146 first contact and 504 second contact individuals were identified, and 146 first contact samples were collected and analyzed," health workers said in the statement. 

The affected place is about 500 kilometers south of Siberia. The Russian state news service, Tass, confirmed the immigration closure to prevent the passage of private vehicles and the transport of merchandise.  

It is not the first time that Mongolia has resorted to a similar measure on that edge.. A key border crossing with Russia with closed in May 2019 on suspicion that it may have played a role in an outbreak of the plague, leaving several Russian tourists stranded. A couple had died after eating marmot meat in that incident.

The May 2019 incident was reported here. In November 2019, three more cases were reported, one resulting from eating a plague-infected rabbit.

US: CDC investigation update of E. coli 0157 H7 infections now linked to romaine lettuce

CDC has published CDC Investigation Update of E. coli 0157 H7 Infections Now Linked to Romaine Lettuce. Excerpt:

A CDC investigation notice of a multistate outbreak of E. coli 0157:H7 infections has been posted: https://www.cdc.gov/ecoli/2019/o157h7-11-19/index.html  

What is new: 

• Consumers should not eat and retailers and restaurants should not sell or serve any romaine lettuce harvested from the Salinas, Calif. growing region. 

• This advice includes all types of romaine lettuce harvested from Salinas, such as whole heads of romaine, hearts of romaine, and packages of precut lettuce and salad mixes that contain romaine, including baby romaine, spring mix, Caesar salad, and organic romaine. 

• If you have romaine lettuce at your home or restaurant and the label says “Salinas” (whether alone or with the name of another location). don’t eat it. Throw it away. If you don’t know if the lettuce is romaine or whether a salad mix contains romaine, don’t eat it or serve it. Throw it away. 

• Most romaine lettuce products are labeled with a harvest location showing where they were grown. Do not eat, serve, or sell any lettuce labeled as grown in Salinas, regardless of any other location on the label. 

• Restaurants and retailers should check the label on bags or boxes of romaine lettuce or ask their suppliers about the source of their romaine lettuce. 

Latest outbreak information:  

• A total of 40 people infected with the outbreak strain of coli 0157:H7 have been reported from 16 states. 

• A total of 27 hospitalizations have been reported. Five people have developed hemolytic uremic syndrome, a type of kidney failure. No deaths have been reported. 

• Epidemiologic and laboratory evidence and interviews with ill people indicate that romaine lettuce from the Salinas, Calif., growing region may be contaminated with coli O157:H7 and is making people sick. 

• FDA is tracing the romaine lettuce eaten by ill people in this outbreak. Preliminary information collected indicates that the lettuce eaten by some of the ill people was grown in Salinas, Calif. No common grower, supplier, distributor, or brand of romaine lettuce has been identified. 

• The USDA has recalled several products containing romaine lettuce due to possible coli contamination. 

• Laboratory data confirmed this outbreak is caused by the same strain of coli O157:H7 that caused previous outbreaks linked to leafy greens in 2017 and romaine lettuce in 2018. 

• This investigation is ongoing and CDC will provide updates when more information becomes available. 

About Shiga toxin-producing E. coli:  

• People get sick from Shiga toxin-producing E. coli an average of 3 to 4 days after swallowing the germ. 

• Most people get diarrhea (often bloody), severe stomach cramps, and vomiting. 

• Most people recover within a week, but some illnesses can last longer and be more severe. 

• Antibiotics are not recommended for patients with suspected E. coli infections until diagnostic testing can be performed and E. coli infection is ruled out.

US: Tainted pork, ill consumers and an investigation thwarted

Via The New York Times: Tainted Pork, Ill Consumers and an Investigation Thwarted. Excerpt:

It was 7 a.m. on Independence Day when a doctor told Rose and Roger Porter Jr. that their daughter could die within hours. For nearly a week, Mikayla, 10, had suffered intensifying bouts of fever, diarrhea and stabbing stomach pains. 

That morning, the Porters rushed her to a clinic where a doctor called for a helicopter to airlift her to a major medical center.  

The gravity of the girl’s illness was remarkable given its commonplace source. She had gotten food poisoning at a pig roast from meat her parents had bought at a local butcher in McKenna, Wash., and spit-roasted, as recommended, for 13 hours. 

Mikayla was one of nearly 200 people reported ill in the summer of 2015 in Washington State from tainted pork — victims of the fastest-growing salmonella variant in the United States, a strain that is particularly dangerous because it is resistant to antibiotics.

 What followed was an exhaustive detective hunt by public health authorities that was crippled by weak, loophole-ridden laws and regulations — and ultimately blocked by farm owners who would not let investigators onto their property and by their politically powerful allies in the pork industry. 

The surge in drug-resistant infections is one of the word’s most ominous health threats, and public health authorities say one of the biggest causes is farmers who dose millions of pigs, cows and chickens with antibiotics to keep them healthy — sometimes in crowded conditions before slaughter.

Overuse of the drugs has allowed germs to develop defenses to survive. Drug-resistant infections in animals are spreading to people, jeopardizing the effectiveness of drugs that have provided quick cures for a vast range of ailments and helped lengthen human lives over much of the past century.

But public health investigators at times have been unable to obtain even the most basic information about practices on farms. Livestock industry executives sit on federal Agriculture Department advisory committees, pour money into political campaigns and have had a seat at the table in drafting regulations for the industry, helping to ensure that access to farms is generally at the owners’ discretion. 

Dr. Parthapratim Basu, a former chief veterinarian of the Agriculture Department’s Food Safety and Inspection Service, said the pork industry regularly thwarted access to information on antibiotic use. 

“When it comes to power, no one dares to stand up to the pork industry,” he said, “not even the U.S. government.”

DRC: 12 Kwango province health zones affected by Konzo disease

As if the DR Congo didn't have enough to deal with, province26.drc.net reports: DRC: 12 health zones affected by Konzo disease (Kwango). The Google translation, with a link to a definition of the disease:

Kwango Provincial Health Division Chief Pierre Mwela says 12 of the 14 health zones in the province are affected by Konzo disease. 

He said it Saturday, July 20 at Okapi Radio. 

The patients show signs of malnutrition and weaknesses in the upper and lower limbs. This disease affects the nerves of the individual and mainly causes paralysis of the lower limbs. The affected subject has deformed limbs and especially has difficulty walking because he has no balance, notes Mr. Mwela.  

The cause of this disease is mainly related to the consumption of cassava which has not experienced retting, a technique that eliminates the toxic substances of certain food plants. 

Pierre Mwela adds that several households are attacked. But to date, there is only preventive treatment. 

The Italian rights NGO ISCO sensitizes the population of Kwango on this disease which mainly affects children.  

According to Rachel Muwawa, ISCO's Communications Officer, this awareness concerns six sites already identified with 4,800 households. Targeted households will receive information needed to prevent this disease, the source said. 

Rachel Muwawa calls on the country's authorities to increase awareness and care for children and women with the disease.  

Konzo is a disease that dates back decades. It is experiencing a recrudescence, to date, following chronic malnutrition in this province, say the health authorities.

ECDC rapid risk assessment: Public health risks related to communicable diseases during the hajj 2019, Saudi Arabia, 9–14 August

ECDC has published Rapid risk assessment: Public health risks related to communicable diseases during the hajj 2019, Saudi Arabia, 9–14 August 2019. The executive summary: 

Main conclusions and options for response 

In 2019, the hajj will take place between 9 and 14 August. 

The risk for EU/EEA citizens to become infected with communicable diseases during the 2019 hajj is considered low, thanks to the vaccination requirements for travelling to Makkah (Mecca) and the Saudi Arabian preparedness plans that address the management of health hazards during and after hajj.   

As with other mass gathering events, the risk of communicable disease outbreaks is greatest for food- and waterborne diseases and respiratory diseases. Outbreaks of MERS-CoV continue to be reported from the Arabian Peninsula, specifically from Saudi Arabia, which implies that there is a risk of importation of cases to Europe after the hajj.  

The risk of vaccine-preventable and vector-borne diseases is considered low if preventive measures are applied.   

Advice for those making the hajj 

Prior to travelling 

It is important that travellers seek advice from healthcare providers on the health requirements and recommendations for Saudi Arabia. Travellers should be advised to follow recommendations issued by the Saudi Arabian Ministry of Health and WHO. Advice issued by ECDC should also be taken into account.  

According to the Saudi authorities, pilgrims are required to provide proof of vaccination with the conjugated meningococcal ACW135Y vaccine administered no less than ten days prior to arrival in Saudi Arabia in order to obtain an entry visa. Travellers making the hajj should be up to date with immunisations routinely administered in their EU country of residence, including vaccinations for measles, mumps and rubella (MMR) and diphtheria-tetanus-polio. Additional vaccinations such as hepatitis A, hepatitis B, influenza, and rabies may be indicated.  

During the hajj 

Travellers making the hajj should take the following into account:  

• Pay attention to personal hygiene and adhere to food and water hygiene regulations in order to decrease the risk of gastrointestinal illnesses. 

• Practise respiratory hygiene and cough etiquette to reduce the risk of respiratory infections. 

• Practise insect and tick bite avoidance measures day and night. 

• Visit only licensed barbers for shaving. 

• Due to the expected high temperatures, avoid direct sun exposure and drink sufficient amounts of liquid. 

After the hajj 

Travellers returning from the hajj should seek medical attention immediately if they experience symptoms suggestive of any type of infection, e.g. gastrointestinal or respiratory. They should also mention their travel history to their healthcare provider. 

Due to continuing reports of MERS-CoV disease in Saudi Arabia, people returning from the hajj should be made aware of the need to seek immediate medical advice if they have a fever (38 ºC and over), cough or difficulties breathing within 14 days of their return. 

Travel history and previous hospitalisation should be reported to the healthcare provider if a person returning from the hajj requires hospitalisation within one year after returning from the hajj. This is to ensure that the possible acquisition of antimicrobial-resistant (AMR) bacteria will be considered and that appropriate measures can be implemented in accordance with national guidelines for the prevention of AMR. 

Death toll from acute encephalitis in east Indian town rises to 129 children

Via Thompson Reuters: Death toll from acute encephalitis in east Indian town rises to 129 children. 

NEW DELHI, June 23 (Reuters) - At least 129 children have now died of Acute Encephalitis Syndrome (AES) in the town of Muzaffarpur in the eastern Indian state of Bihar since an outbreak earlier this month, a medical official said on Sunday. 

The death toll from AES, a fever that affects the central nervous system, has risen from 97 reported last Monday and medical and government officials are facing mounting criticism for struggling to contain the crisis in the town of nearly 350,000 people. 

AES, known as 'brain fever' is caused by any one of a number of viruses. Symptoms include high fever, vomiting and, in severe cases, seizures, paralysis and coma. Infants and elderly people are particularly vulnerable.  

"I received my last update in the afternoon and according to the latest report that I have, 129 children have died so far," Shailesh Prasad Singh, the top state medical official in Muzaffarpur told Reuters by phone. The town lies about 80 km (50 miles) from Patna, the state capital. 

The precise causes of AES are not known, though a majority of medical professionals say it is linked to a ferocious heat-wave. 

Some studies have blamed toxins in lychees, a fruit grown in abundance in orchards around Muzaffarpur. But many families told Reuters last week that their children had not eaten them in recent weeks. 

Singh said a team of experts, including doctors, paramedics and other government officials were working "round the clock" to contain the spread of AES, which killed more than 350 children in a previous outbreak in Bihar in 2014.  

Doctors from other parts of the country had been dispatched to Muzaffarpur to help staff at the Sri Krishna Medical College Hospital which had to evict a group of sick inmates from a ward to accommodate the surge in AES patients. Most of the children who died were being treated at the hospital.  

Nearly half of all children in Muzaffarpur are underweight, and a similar number are stunted, making them vulnerable to AES, which grips the town almost every year when summer temperatures surge. 

As the death toll mounts, both the Bihar and the federal governments have come under criticism for their inability to save children, and doctors and government officials have faced angry protests. 

On Sunday, the Bihar government suspended a doctor in Muzaffarpur for dereliction of duties, news agency ANI, a Reuters affiliate, said. 

India's Federal Health and Family Welfare Minister Harsh Vardhan, who is himself a doctor, said last week that health officials have finalised plans for construction of a 100-bed paediatric intensive care unit in Muzaffarpur, but gave no timeframe for when it would be built.

UK: Hancock pledges hospital food overhaul after listeria deaths

Via The Guardian: Hancock pledges hospital food overhaul after listeria deaths. Excerpt:

Health secretary Matt Hancock has ordered a “root and branch” review of NHS food after two more patient deaths were linked last week to a listeria outbreak. The new deaths bring the number of suspected fatalities to five and doctors have warned that further cases could occur.  

Hancock said he was “incredibly concerned” after it emerged the patients were suspected of dying as a result of eating pre-packaged sandwiches and salads linked by the same supplier, The Good Food Chain. 

The affected products have since been withdrawn from hospitals and Public Health England said evidence suggested all the deaths had occurred before the items were removed from circulation on 25 May. 

“We need a radical new approach to the food that is served in our NHS,” added Hancock. “Our NHS should be at the forefront of supporting people to make healthy choices.”  

A Public Health England official said investigations into the outbreak were taking place and were being conducted in partnership with the Food Standards Agency. Listeria is caused by the bacterium Listeria monocytogenes and can trigger very severe disease in humans. It usually affects people whose immune systems have been weakened – such as the elderly, pregnant women or patients taking immuno-suppressant drugs. The disease is caught by eating contaminated food.  

The first three deaths were at Manchester University NHS foundation trust and Aintree University Hospital NHS foundation trust in Liverpool. One of the two new cases is understood to have died after these three cases. However, the other patient died before the three succumbed. Doctors have only just discovered the death was linked to the same strain of the bacterium. 

“These two cases had already been reported to Public Health England but were re-analysed using whole genome sequence data,” said Dr Catherine Rees, associate professor in microbiology at Nottingham University. “This showed that the listeria isolated from these patients were highly likely to have come from the same source.”

The trusts where the latest two victims were receiving treatment have not yet been named, although PHE said there are now seven trusts across the country dealing with listeria cases. The first case showed symptoms on 25 April and sandwiches and salads were withdrawn on 25 May. It is understood that some of the products were sold at hospitals, while others were given to patients.

“Pre-packed sandwiches are recurrently incriminated in the UK in listeriosis episodes,” added Professor Jose Vazquez-Boland of Edinburgh University. “For example, in 2017 there was an outbreak in Yorkshire and the Humber that also involved sandwiches supplied to hospitals. There is clearly a warning here that microbiological controls for listeria need to be stepped up with pre-packed sandwiches. 

“In general, foods involved in listeria infections are industrially processed foods that are kept at refrigeration temperatures and are consumed without previous cooking.”  

The Good Food Chain, which supplied 43 NHS trusts across the UK, voluntarily ceased production. The company was supplied with meats from North Country Cooked Meat. Some of these have since tested positive for the outbreak strain of Listeria monocytogenes and the company has also stopped production. 

“Since the source has been traced, there should be no more exposure, but the bacterium’s long incubation period means that the risk of new cases coming to light cannot be ruled out yet,” added Rees.
