With recent bird flu outbreaks, many wonder if everyday food items like milk and eggs pose a transmission risk. Here’s what experts say.

Amid bird flu outbreak in the US and UN body World Health Organization (WHO) confirming the presence of H5N1 bird flu strain in raw milk, concerns have been rising around consuming milk, chicken and eggs. As it has not been long since the world left behind the fears of coronavirus, the world dreads the emergence of avian influenza affecting humans. Bird flu spreads through direct contact with infected birds or their droppings; so far there is no evidence of human-to-human transmission. A person in Texas recently tested positive for avian influenza making it a second case of H5N1 bird flu in the United States, the first one being a poultry worker in Colorado in 2022. This is also the case of first human being infected by H5N1 bird flu via a cow. (Also read | Bird flu outbreak in Kerala’s Alappuzha: Should you be concerned? Symptoms, prevention tips of H5N1 flu)

While the virus has been around since 1996, recent years since 2020 have seen a massive surge among birds and mammals, killing tens of millions of poultry, infections in wild birds and also land and marine mammals. However, in the recent outbreak, cows and goats have also been affected. “The case in texas is the first human infected by avian influenza by a cow,” said Wenqing Zhang, head of the global influenza programme at the World Health Organization.

Amid spread of H5N1 influenza virus is cows and poultry, is it safe to have eggs and milk? Here’s what experts say.

“Bird flu, also known as avian influenza, is primarily transmitted through direct contact with infected birds or their droppings. The virus is not typically transmitted through consumption of properly cooked eggs or pasteurized milk. When poultry products are cooked thoroughly, the heat kills the virus, making them safe to eat. However, it’s important to practice good hygiene and ensure proper cooking and handling of poultry products to reduce any potential risk of infection. This includes washing hands thoroughly after handling raw poultry and avoiding cross-contamination with other foods,” says Dr Rahul Agarwal Consultant Internal Medicine CARE Hospitals Hitech City Hyderabad.

“With recent bird flu outbreaks, many wonder if everyday food items like milk and eggs pose a transmission risk. The good news is, contracting bird flu, also known as avian influenza, through these common breakfast staples is highly unlikely. Bird flu primarily spreads among birds through their saliva, faeces, and respiratory secretions,” says Dr Neha Rastogi Panda, Consultant-Infectious Diseases, Fortis Memorial Research Institute, Gurugram.

Can people get infection from eggs and milk?

While some rare human infections have occurred, these typically involve close contact with infected birds. So, can eggs or milk harbour the virus and reach you?

“Eggs go through strict regulations and hygiene protocols during production and packaging. This significantly reduces the chance of contamination. The bigger factor is how you handle them at home. Thorough cooking is key – avoid runny yolks or dishes with undercooked eggs. Always wash your hands after handling them,” says Dr Panda.

“Milk safety hinges on pasteurization, a heat treatment that destroys viruses, including bird flu. Virtually all commercially available milk undergoes this process, making it safe for consumption. Raw milk, however, is a different story. While there’s limited data on bird flu transmission through raw milk, it’s generally discouraged due to the risk of other foodborne illnesses,” adds the expert.

If you’re concerned about bird flu and your food, focus on safe handling practices. Cook eggs thoroughly and stick to pasteurized dairy products. It’s also wise to stay updated on the outbreak from reputable sources like the CDC or national health agencies.

“Remember, the risk of getting bird flu from eggs and milk is extremely low. By following basic hygiene and food safety measures, you can continue to enjoy these breakfast favourites without worry,” concludes Dr Panda.

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.
