Provincial authorities across Canada have issued a recall of a popular brand of gin after it was discovered that some bottles may contain 77% alcohol rather than the 40% listed on the bottle.

The province of Ontario was the first to sound the alarm over the batch of bottles from Bombay Sapphire London Dry Gin. On Tuesday, the liquor authority said that an investigation by its quality assurance team had discovered the alcohol content to be almost double what was noted on the 1.14L bottle.

“This product is not safe for consumption,” the Liquor Control Board of Ontario said in its notice of the recall. “Consuming a product with an alcohol content of 77% could cause serious illness.”

The move was soon echoed by four other liquor authorities across the country, stretching from Newfoundland and Labrador to Saskatchewan.
