As temperatures rise, so do myths about sunscreen

Published

 on

Experts are warning Canadians not to heed misinformation spread online that sunscreen can cause cancer, stressing that proper use of the right lotions or sprays is, in fact, one of the best ways to prevent potentially deadly ailments like melanoma.

Quebec’s Order of Chemists warned last week against what it called a worrying trend circulating on social networks where some influencers spread false and misleading information about sunscreen, claiming that its ingredients are harmful to the skin and can cause cancer. The group said the assertions, devoid of scientific basis, can endanger public health.

One such influencer on TikTok recently warned their 570,000 followers to not use any sunscreen whose ingredients have “any funny words other than zinc.”

Julia Carroll, a dermatologist in Toronto, says much of the misinformation fails to look at the medical literature as a whole on sunscreen ingredients, which points to their safety.

“I’m a board-certified dermatologist,” Carroll said. “I have 20 plus years of training and education and we dedicate ourselves to looking after the health of our patients’ skin. And one person on TikTok that just happens to have a lot of followers can sway someone’s opinion. It’s really frustrating for all of us.”

She says some influencers overlook how it’s the dose that makes the poison. Too much of almost any substance can kill you while, in small amounts, even toxic substances like botulinum toxin can be safe.

Some influencers claim certain sunscreen ingredients cause cancer or other ailments. Others say sunshine is the best way to get vitamin D.

According to the Canadian Cancer Society, about 65 per cent of melanoma cases are due to ultra-violet (UV) radiation, the main source of which is the sun. Melanoma is a form of skin cancer that starts in the skin’s pigment-producing cells or melanocytes.

Skin cancer survivor stresses importance of checking moles frequently

Maureen Meehan, a London, Ont., resident who was diagnosed with Stage 3 melanoma in 2017 and had successful surgery, shares how to check moles in areas you can’t reach and why you shouldn’t take the threat of skin cancer lightly.

The authors of a report on projected estimates of cancer in Canada for 2024 noted the incidence of melanoma continues to increase for both males and females, although mortality has remained largely stable.

Cheryl Peters, a senior scientist at the B.C. Centre for Disease Control and B.C. Cancer, attributed the rise in melanoma to a combination of factors. People may expose more skin to stay cool during hotter summers with climate change, she said. Canada’s aging population also matters since the risk of most cancers increases the older you get.

Check UV index

In Canada, weather forecasts and apps include information on the UV index.

“Once you start to hit that UV index of 3, you really want to be wearing your sunscreen and reapplying it regularly,” Peters said on CBC Radio’s Just Asking.

The first layer of defence is to reduce time in the sun during its peak rays of 10 a.m. to 3 p.m., by seeking shade and covering up as much of your skin as you can with clothing that is made from tightly woven fabric or clothes labelled with a UPF (UV protection factor), a wide-brimmed hat and sunglasses.

It’s true that a bit of sun exposure does help the body produce vitamin D, which is important for our bones and other health aspects.

But Carroll says people shouldn’t rely on it to get their vitamin D. “If vitamin D is really important to you, the easiest way and most consistent way to get it is through a supplement,” she said.

Sunscreen explained

Sunscreen comes in two major types, mineral and chemical.

Mineral sunscreens contain zinc oxide or titanium dioxide. The mineral flecks create a barrier reflecting UV light before it penetrates the skin. Because mineral sunscreens create a physical block and aren’t absorbed, the formulations can have a white appearance.

Chemical sunscreens come as creams or sprays. The ingredients form a thin protective film that absorbs UV rays and converts them into heat before they penetrate the skin.

Dermatologist Dr. Monica Li discusses the meaning of SPF and the differences between chemical and mineral sunscreens.

Canadian guidelines recommend making applying sunscreen part of your morning routine and putting on a “generous amount” — one to two teaspoons for the head and neck, and two to three tablespoons for the body of an average-sized adult.

Guidelines laid down by the Canadian Dermatology Association require an SPF rating of at least 30.

Experts also recommend broad-spectrum sunscreens that protect against both UVA rays, which lead to signs of aging like wrinkles, and UVB rays, which lead to sunburn.

Chemical sunscreens can lose their efficacy when exposed to extreme heat according to a 2012 study in the journal of the American Academy of Dermatology. You can tell if sunscreen may have been exposed to extreme heat if its components have started to separate.

So during extreme heat, when temperatures reach 32 C or above, with high humidity, for at least a few days, mineral sunscreens are preferable, says Jacqueline Watchmaker, a dermatologist in Scottsdale, Ariz., and a spokesperson for the academy.

Otherwise, there isn’t a health-based reason to choose one type of sunscreen over another, says Peters, who researches the prevention of occupational and environmental chronic diseases like cancer.

Chemical sunscreens can cause a skin reaction like a rash in a small number of people, she says. In those cases, shift to a mineral-based product.

Also, chemical sunscreens are suspected of causing harm to some coral reefs so if you’re vacationing in areas with reefs, that’s another time to consider using a mineral-based option, Peters says.

Lip balms that have a SPF rating are also an important form of protection that a lot of people miss, Peters said.

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.”
