Canadians are being warned not to drink bleach after U.S. President Donald Trump casually suggested injecting the corrosive chemical as a COVID-19 cure on Thursday, which — spoiler — it isn't.

Although Trump now says that he was being "sarcastic," it seems that the idea of drinking bleach has miraculously caught on, even in parts of Canada.

On Friday, Winnipeg Mayor Brian Bowman urged Canadians to refrain from ingesting household cleaning products.

"I can't believe I have to say this," he said, "but I'm going to just urge Winnipeggers to not consume or inject any disinfectants. That includes Windex, that includes Clorox, that includes Lysol and other household cleaning products."

Although there haven't been any reports in Winnipeg of locals drinking household cleaners, Bowman says that he's received multiple messages online asking him about it.

"These are products not to be consumed or injected and we would urge people, please observe the safety warnings on the labels and follow the expertise from health officials," he said.

Manitoba Provincial Health Officer Dr. Brent Roussin also chimed in at a press conference, urging Canadians not to ingest or inject any household cleaning products.

The company that makes Lysol wipes is similarly reminding people not to ingest cleaning products.

"As a global leader in health and hygiene products, we must be clear that under no circumstance should our disinfectant products be administered into the human body (through injection, ingestion, or any other route)," the statement says.

"Please read the label and safety information."

So, please, Canada; let's refrain from drinking cleaning products and stick to using bleach for its primary purpose: cleaning household surfaces.
