Avian influenza spread: WHO gives public health warning as FDA calms food safety concerns – Food Ingredients First

Published

 on


23 April 2024 — The World Health Organization (WHO) has warned that the ongoing spread of avian influenza poses a “significant public health concern” and urged health authorities, especially in the US, to closely monitor infections in cows. However, the US FDA maintains that the virus is not currently a concern to consumer health and downplayed its impact on commercial milk production.

Earlier this month, the largest producer of fresh eggs in the US halted production at a Texas plant after bird flu was detected in its chickens. Cal-Maine Foods said that about 3.6% of its total flock was destroyed after the infection.

However, the virus, also known as H5N1, has now been found in at least 26 dairy herds across eight US states, marking the first time this strain of bird flu has been detected in cattle, according to officials.

At least 21 states have restricted cattle importations from states where the virus is known to have infected dairy cows.

The US Department of Agriculture’s Animal and Plant Health Inspection Service strongly recommends minimizing the movement of cattle, but has not issued federal quarantine orders.

Public health threat
The US Centers for Disease Control and Prevention (CDC) confirmed this month that a dairy worker in Texas, who reportedly had exposure to dairy cattle presumed to have had avian influenza, contracted the virus and is now recovering.

“This infection does not change the H5N1 bird flu human health risk assessment for the US general public, which CDC considers to be low,” the agency said in a press release, while acknowledging that people who come into more frequent contact with possibly infected birds or other mammals have a higher risk.

Meanwhile, WHO’s chief scientist, Dr. Jeremy Farrar, told reporters recently in Geneva, Switzerland, that H5N1 has had an “extremely high” mortality rate among the several hundred people known to have been infected with it to date.

US health officials have downplayed the impact of bird flu on food safety and industry production.However, no human-to-human H5N1 transmission has yet been recorded.

“H5N1 is an influenza infection, predominantly started in poultry and ducks and has spread effectively over the course of the last one or two years to become a global zoonotic — animal — pandemic,” said Farrar.

“The great concern, of course, is that in doing so and infecting ducks and chickens — but now increasingly mammals — the virus now evolves and develops the ability to infect humans.

“And then critically, the ability to go from human-to-human transmission.”

Concerns with cattle
US health officials have stressed that bird flu’s risk to the public is low, and the country’s food supply remains safe and stable.

“At this time, there continues to be no concern that this circumstance poses a risk to consumer health or that it affects the safety of the interstate commercial milk supply,” the FDA said in a statement.

According to officials, farmers are being urged to test cows that show symptoms of infection and separate them from the herd, where they usually recover within two weeks.

US producers are not permitted to sell milk from sick cows, while milk sold across state lines must be pasteurized or heat-treated to kill viruses, including influenza.A dairy worker in Texas reportedly contracted the virus after exposure to cattle.

“We firmly believe that pasteurization provides a safe milk supply,” Tracey Forfa, director of the FDA’s Center for Veterinary Medicine, told a webinar audience last week.

However, WHO’s Farrar has urged further caution by public health authorities “because it [the virus] may evolve into transmitting in different ways.”

“Do the milking structures of cows create aerosols? Is it the environment which they’re living in? Is it the transport system that is spreading this around the country?” he said.

“This is a huge concern, and I think we have to…make sure that if H5N1 did come across to humans with human-to-human transmission that we were in a position to immediately respond with access equitably to vaccines, therapeutics and diagnostics.”

According to a new European Food Safety Authority report, outbreaks of avian influenza continue to spread in the EU and beyond.

Canada to donate up to 200,000 vaccine doses to combat mpox outbreaks in Africa

Published

 on

 

The Canadian government says it will donate up to 200,000 vaccine doses to fight the mpox outbreak in Congo and other African countries.

It says the donated doses of Imvamune will come from Canada’s existing supply and will not affect the country’s preparedness for mpox cases in this country.

Minister of Health Mark Holland says the donation “will help to protect those in the most affected regions of Africa and will help prevent further spread of the virus.”

Dr. Madhukar Pai, Canada research chair in epidemiology and global health, says although the donation is welcome, it is a very small portion of the estimated 10 million vaccine doses needed to control the outbreak.

Vaccine donations from wealthier countries have only recently started arriving in Africa, almost a month after the World Health Organization declared the mpox outbreak a public health emergency of international concern.

A few days after the declaration in August, Global Affairs Canada announced a contribution of $1 million for mpox surveillance, diagnostic tools, research and community awareness in Africa.

On Thursday, the Africa Centres for Disease Control and Prevention said mpox is still on the rise and that testing rates are “insufficient” across the continent.

Jason Kindrachuk, Canada research chair in emerging viruses at the University of Manitoba, said donating vaccines, in addition to supporting surveillance and diagnostic tests, is “massively important.”

But Kindrachuk, who has worked on the ground in Congo during the epidemic, also said that the international response to the mpox outbreak is “better late than never (but) better never late.”

“It would have been fantastic for us globally to not be in this position by having provided doses a much, much longer time prior than when we are,” he said, noting that the outbreak of clade I mpox in Congo started in early 2023.

Clade II mpox, endemic in regions of West Africa, came to the world’s attention even earlier — in 2022 — as that strain of virus spread to other countries, including Canada.

Two doses are recommended for mpox vaccination, so the donation may only benefit 100,000 people, Pai said.

Pai questioned whether Canada is contributing enough, as the federal government hasn’t said what percentage of its mpox vaccine stockpile it is donating.

“Small donations are simply not going to help end this crisis. We need to show greater solidarity and support,” he said in an email.

“That is the biggest lesson from the COVID-19 pandemic — our collective safety is tied with that of other nations.”

How many Nova Scotians are on the doctor wait-list? Number hit 160,000 in June

Published

 on

 

HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.

The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.

Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.

“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”

The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.

A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.

Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.

“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.

Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.

The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.

“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

Newfoundland and Labrador monitoring rise in whooping cough cases: medical officer

Published

 on

 

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.

Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.

Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.

Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.

The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.

“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.

Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.

Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.

Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.

A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
