Avian flu and dogs: How to protect your pets as cases of the fatal virus rise

Published

 on

After a dog in Ontario recently contracted avian flu and died, experts say pet owners should be more vigilant — even though the risk of transmission to mammals remains low.

The infection strain, called H5N1, also known as bird flu, is a highly pathogenic form of avian influenza virus A and circulates most easily between birds. Although it’s rare for it to spread to mammals, numbers are increasing across Canada.

The dog from Oshawa, Ont., was infected with the bird flu after chewing on a wild goose, and then developing “clinical signs,” the Canadian Food Inspection Agency (CFIA) said Tuesday. The case was confirmed on April 1 and the necropsy, which showed the respiratory system was involved in the death, was completed on April 3.

Although the CFIA said the risk of humans and domestic pets contracting the virus remains low, Scott Weese, a veterinary internal medicine specialist and professor at the University of Guelph’s Ontario Veterinary College, said pet owners should still exercise caution as the risk is not zero.

“This dog could have easily been missed because if they hadn’t noticed the encounter with the bird, that wouldn’t have triggered any testing,” he said. “So is this the only dog that’s been infected in Canada, or is it the only dog we’ve diagnosed? It’s hard to say.”

Overall, domestic pets getting infected with the bird flu is rare, but the problem occurs when “you have a lot of background noise going on,” he explained.

“If it’s a rare, one-in-a-million chance, but you get millions and millions of birds, that one-in-a-million chance starts to get more common.”

The World Health Organization (WHO) has called the ongoing circulation among poultry concerning. During a WHO media conference on Thursday, Dr. Maria Van Kerkhove, an infectious disease epidemiologist, said the transmission from poultry to mammals is “always of concern.”

“As a pathogen that has that zoonotic risk, that spillover risk, the concern is if it has that amplification aspect,” she said. ” It is something the organization takes very seriously as pathogens that have epidemic and pandemic potential.”

 

Hunting dogs may be more at risk

Transmission between mammals usually happens when an animal eats or chews on a bird, Levon Abrahamyan, a virologist at the University of Montreal, said.

“These cases are very rare, and they happen when there is very direct contact with a large number of viral particles,” he said. “And this can happen with a dog or any animal, including a human, is in close contact with a high concentration of the virus.”

This is why the bird flu has been transferred more to the “opportunistic carnivores,” like foxes, raccoons, skunks, wild cats and ferrets, Abrahamyan said.

For example, last month eight skunks that were found dead in the Vancouver area tested positive for the H5N1 avian influenza. B.C. health officials said the skunks may have contracted the virus by eating infected wild birds.

In terms of domestic animals getting infected, Abrahamyan believes hunting dogs are most at risk.

Duck hunting in Canada is typically in the fall, but if the bird flu continues to spread across the country, the virus could still be present in September and October.

“In the case of domestic dogs, it’s very rare the dog could get it. But a dog that can be at higher risk is the hunting dog,” Abrahamyan warned. “I would highly recommend for hunters to take precautions now that we have a highly pathogenic influenza among wild birds.

“They should watch their dogs as a dead bird has a higher possibility of having the virus, as you don’t know what caused the death.”

 

How to protect your pet from bird flu

The avian flu affects all types of birds, like ducks, swans and geese. It especially affects those that tend to stay in flocks or congregate together. The virus is transmitted from bird to bird through secretions, feces and contaminated feed, water and equipment, according to the Canadian Centre for Occupational Health and Safety.

It can also be fatal, so when scavenger animals like skunks (or even a dog) eat an infected bird, they can also get the virus.

“We don’t want dogs roaming around where they have a close encounter with, say, a goose, as geese tend to stand their ground,” Weese said. “Your dog goes up and barks at it and the goose will bark back. And that’s that close contact that we want to prevent.”

If there is a park that dog owners enjoy, but it’s flooded with geese this time of year, Weese said it’s probably not a great place to take your pet, as the goal is to “reduce that bridge between wildlife and domestic animals.”

Weese said he has two dogs of his own and lives in rural Ontario, so there are ducks and geese all over the place.

“I’m not being overly restrictive with my dogs, but I’m not going to let them go chase geese in the pond. If there’s a dead bird, I’m certainly going to keep them away and I going be more restrictive. But I’m not going to keep them completely on leash in areas where I know that we don’t see a lot of birds.”

In terms of feeding pets raw meat, Weese said if a dog is on a raw meat diet, there shouldn’t be a risk of avian flu because it’s the same as buying poultry from the grocery store.

“There’s no risk of influenza there,” he explained. “Poultry is really, really well monitored. They’re not going into the food chain if they’re infected.”

But he warned that dog owners should not hunt their own birds to feed their dog, or have their own backyard poultry, as these are “big amplifying” sources for the virus.

 

Are there risks with birdfeeders and avian flu?

As cases of avian flu steadily rise in Canada, Weese said birdfeeders can pose a risk, especially for “birds themselves, as feeders are co-mingling sites.”

“You’re bringing together birds that might not be getting close together otherwise. And you’re also creating more of that risk of the bird’s secretions and bird poop that’s on the feeder. So it might be a place where you’re going to amplify the virus if one of them has it,” he said.

There also is the danger of the bird feeder bringing in more animals that are close to the human and pet population.

He recommends keeping cats indoors if possible but acknowledges that may be difficult to do in some situations.

“If you have an outdoor cat in particular, it’s probably not good to have a feeder as it creates a greater chance for that cat to catch a bird and then the cat is more likely to catch a sick bird,” Weese added.

If people do want to keep their feeder or bird bath around this spring and summer, Abrahamyan recommends washing it frequently with a mixture of vinegar and soap, in order to maintain a clean environment.

“You don’t want your bird feeder or bath to become a source of the transmission of this virus, so regularly clean it and it should be fine,” he said.

In December 2022, the British Columbia Society for the Prevention of Cruelty to Animals (BC SPCA) urged residents to take down their bird feeders, warning it puts birds — including great horned owls, bald eagles, great blue herons, ducks and geese, and crows — at risk of the virus.

The BC SPCA called on people to remove seed and suet bird feeders, in order to discourage birds from gathering and potentially spreading the disease.

These feeders create “unnatural congregations” of birds who can pass the virus to one another, or contract it from other bird droppings on the ground underneath the feeder as they forage for fallen seed, the organization stated.

Health Canada approves updated Moderna COVID-19 vaccine

Published

 on

 

TORONTO – Health Canada has authorized Moderna’s updated COVID-19 vaccine that protects against currently circulating variants of the virus.

The mRNA vaccine, called Spikevax, has been reformulated to target the KP.2 subvariant of Omicron.

It will replace the previous version of the vaccine that was released a year ago, which targeted the XBB.1.5 subvariant of Omicron.

Health Canada recently asked provinces and territories to get rid of their older COVID-19 vaccines to ensure the most current vaccine will be used during this fall’s respiratory virus season.

Health Canada is also reviewing two other updated COVID-19 vaccines but has not yet authorized them.

They are Pfizer’s Comirnaty, which is also an mRNA vaccine, as well as Novavax’s protein-based vaccine.

These people say they got listeria after drinking recalled plant-based milks

Published

 on

 

TORONTO – Sanniah Jabeen holds a sonogram of the unborn baby she lost after contracting listeria last December. Beneath, it says “love at first sight.”

Jabeen says she believes she and her baby were poisoned by a listeria outbreak linked to some plant-based milks and wants answers. An investigation continues into the recall declared July 8 of several Silk and Great Value plant-based beverages.

“I don’t even have the words. I’m still processing that,” Jabeen says of her loss. She was 18 weeks pregnant when she went into preterm labour.

The first infection linked to the recall was traced back to August 2023. One year later on Aug. 12, 2024, the Public Health Agency of Canada said three people had died and 20 were infected.

The number of cases is likely much higher, says Lawrence Goodridge, Canada Research Chair in foodborne pathogen dynamics at the University of Guelph: “For every person known, generally speaking, there’s typically 20 to 25 or maybe 30 people that are unknown.”

The case count has remained unchanged over the last month, but the Public Health Agency of Canada says it won’t declare the outbreak over until early October because of listeria’s 70-day incubation period and the reporting delays that accompany it.

Danone Canada’s head of communications said in an email Wednesday that the company is still investigating the “root cause” of the outbreak, which has been linked to a production line at a Pickering, Ont., packaging facility.

Pregnant people, adults over 60, and those with weakened immune systems are most at risk of becoming sick with severe listeriosis. If the infection spreads to an unborn baby, Health Canada says it can cause miscarriage, stillbirth, premature birth or life-threatening illness in a newborn.

The Canadian Press spoke to 10 people, from the parents of a toddler to an 89-year-old senior, who say they became sick with listeria after drinking from cartons of plant-based milk stamped with the recalled product code. Here’s a look at some of their experiences.

Sanniah Jabeen, 32, Toronto

Jabeen says she regularly drank Silk oat and almond milk in smoothies while pregnant, and began vomiting seven times a day and shivering at night in December 2023. She had “the worst headache of (her) life” when she went to the emergency room on Dec. 15.

“I just wasn’t functioning like a normal human being,” Jabeen says.

Told she was dehydrated, Jabeen was given fluids and a blood test and sent home. Four days later, she returned to hospital.

“They told me that since you’re 18 weeks, there’s nothing you can do to save your baby,” says Jabeen, who moved to Toronto from Pakistan five years ago.

Jabeen later learned she had listeriosis and an autopsy revealed her baby was infected, too.

“It broke my heart to read that report because I was just imagining my baby drinking poisoned amniotic fluid inside of me. The womb is a place where your baby is supposed to be the safest,” Jabeen said.

Jabeen’s case is likely not included in PHAC’s count. Jabeen says she was called by Health Canada and asked what dairy and fresh produce she ate – foods more commonly associated with listeria – but not asked about plant-based beverages.

She’s pregnant again, and is due in several months. At first, she was scared to eat, not knowing what caused the infection during her last pregnancy.

“Ever since I learned about the almond, oat milk situation, I’ve been feeling a bit better knowing that it wasn’t something that I did. It was something else that caused it. It wasn’t my fault,” Jabeen said.

She’s since joined a proposed class action lawsuit launched by LPC Avocates against the manufacturers and sellers of Silk and Great Value plant-based beverages. The lawsuit has not yet been certified by a judge.

Natalie Grant and her seven year-old daughter, Bowmanville, Ont.

Natalie Grant says she was in a hospital waiting room when she saw a television news report about the recall. She wondered if the dark chocolate almond milk her daughter drank daily was contaminated.

She had brought the girl to hospital because she was vomiting every half hour, constantly on the toilet with diarrhea, and had severe pain in her abdomen.

“I’m definitely thinking that this is a pretty solid chance that she’s got listeria at this point because I knew she had all the symptoms,” Grant says of seeing the news report.

Once her daughter could hold fluids, they went home and Grant cross-checked the recalled product code – 7825 – with the one on her carton. They matched.

“I called the emerg and I said I’m pretty confident she’s been exposed,” Grant said. She was told to return to the hospital if her daughter’s symptoms worsened. An hour and a half later, her fever spiked, the vomiting returned, her face flushed and her energy plummeted.

Grant says they were sent to a hospital in Ajax, Ont. and stayed two weeks while her daughter received antibiotics four times a day until she was discharged July 23.

“Knowing that my little one was just so affected and how it affected us as a family alone, there’s a bitterness left behind,” Grant said. She’s also joined the proposed class action.

Thelma Feldman, 89, Toronto

Thelma Feldman says she regularly taught yoga to friends in her condo building before getting sickened by listeria on July 2. Now, she has a walker and her body aches. She has headaches and digestive problems.

“I’m kind of depressed,” she says.

“It’s caused me a lot of physical and emotional pain.”

Much of the early days of her illness are a blur. She knows she boarded an ambulance with profuse diarrhea on July 2 and spent five days at North York General Hospital. Afterwards, she remembers Health Canada officials entering her apartment and removing Silk almond milk from her fridge, and volunteers from a community organization giving her sponge baths.

“At my age, 89, I’m not a kid anymore and healing takes longer,” Feldman says.

“I don’t even feel like being with people. I just sit at home.”

Jasmine Jiles and three-year-old Max, Kahnawake Mohawk Territory, Que.

Jasmine Jiles says her three-year-old son Max came down with flu-like symptoms and cradled his ears in what she interpreted as a sign of pain, like the one pounding in her own head, around early July.

When Jiles heard about the recall soon after, she called Danone Canada, the plant-based milk manufacturer, to find out if their Silk coconut milk was in the contaminated batch. It was, she says.

“My son is very small, he’s very young, so I asked what we do in terms of overall monitoring and she said someone from the company would get in touch within 24 to 48 hours,” Jiles says from a First Nations reserve near Montreal.

“I never got a call back. I never got an email”

At home, her son’s fever broke after three days, but gas pains stuck with him, she says. It took a couple weeks for him to get back to normal.

“In hindsight, I should have taken him (to the hospital) but we just tried to see if we could nurse him at home because wait times are pretty extreme,” Jiles says, “and I don’t have child care at the moment.”

Joseph Desmond, 50, Sydney, N.S.

Joseph Desmond says he suffered a seizure and fell off his sofa on July 9. He went to the emergency room, where they ran an electroencephalogram (EEG) test, and then returned home. Within hours, he had a second seizure and went back to hospital.

His third seizure happened the next morning while walking to the nurse’s station.

In severe cases of listeriosis, bacteria can spread to the central nervous system and cause seizures, according to Health Canada.

“The last two months have really been a nightmare,” says Desmond, who has joined the proposed lawsuit.

When he returned home from the hospital, his daughter took a carton of Silk dark chocolate almond milk out of the fridge and asked if he had heard about the recall. By that point, Desmond says he was on his second two-litre carton after finishing the first in June.

“It was pretty scary. Terrifying. I honestly thought I was going to die.”

Cheryl McCombe, 63, Haliburton, Ont.

The morning after suffering a second episode of vomiting, feverish sweats and diarrhea in the middle of the night in early July, Cheryl McCombe scrolled through the news on her phone and came across the recall.

A few years earlier, McCombe says she started drinking plant-based milks because it seemed like a healthier choice to splash in her morning coffee. On June 30, she bought two cartons of Silk cashew almond milk.

“It was on the (recall) list. I thought, ‘Oh my God, I got listeria,’” McCombe says. She called her doctor’s office and visited an urgent care clinic hoping to get tested and confirm her suspicion, but she says, “I was basically shut down at the door.”

Public Health Ontario does not recommend listeria testing for infected individuals with mild symptoms unless they are at risk of developing severe illness, such as people who are immunocompromised, elderly, pregnant or newborn.

“No wonder they couldn’t connect the dots,” she adds, referencing that it took close to a year for public health officials to find the source of the outbreak.

“I am a woman in my 60s and sometimes these signs are of, you know, when you’re vomiting and things like that, it can be a sign in women of a bigger issue,” McCombe says. She was seeking confirmation that wasn’t the case.

Disappointed, with her stomach still feeling off, she says she decided to boost her gut health with probiotics. After a couple weeks she started to feel like herself.

But since then, McCombe says, “I’m back on Kawartha Dairy cream in my coffee.”

B.C. mayors seek ‘immediate action’ from federal government on mental health crisis

Published

 on

 

VANCOUVER – Mayors and other leaders from several British Columbia communities say the provincial and federal governments need to take “immediate action” to tackle mental health and public safety issues that have reached crisis levels.

Vancouver Mayor Ken Sim says it’s become “abundantly clear” that mental health and addiction issues and public safety have caused crises that are “gripping” Vancouver, and he and other politicians, First Nations leaders and law enforcement officials are pleading for federal and provincial help.

In a letter to Prime Minister Justin Trudeau and Premier David Eby, mayors say there are “three critical fronts” that require action including “mandatory care” for people with severe mental health and addiction issues.

The letter says senior governments also need to bring in “meaningful bail reform” for repeat offenders, and the federal government must improve policing at Metro Vancouver ports to stop illicit drugs from coming in and stolen vehicles from being exported.

Sim says the “current system” has failed British Columbians, and the number of people dealing with severe mental health and addiction issues due to lack of proper care has “reached a critical point.”

Vancouver Police Chief Adam Palmer says repeat violent offenders are too often released on bail due to a “revolving door of justice,” and a new approach is needed to deal with mentally ill people who “pose a serious and immediate danger to themselves and others.”
