All Costco locations in Ottawa and Gatineau will be offering free hepatitis A vaccines until at least Friday to anyone who consumed a recalled frozen fruit sold at the store.

The Canadian Food Inspection Agency notified the public that Costco has issued a recall Friday for Nature's Touch Organic Berry Cherry Blend, a mix sold exclusively at Costco. The recall was issued because of a possible hepatitis A contamination.

A spokesperson for Costco Canada said Tuesday the stores have been busy offering the vaccines at all locations, and that they will likely offer the vaccines past Friday if the demand remains high.

Customers receive automated calls

Steve Laroche, his wife and two young children went to get their free hepatitis A vaccines at Costco's Nepean location on Monday night, after they received an automated call from the company alerting them they had recently bought the product.

"It was pretty concerning…especially when we have our two children involved in it," said Laroche.

"They pretty much consumed most of the product…we blend the food into their cereal in the morning."

Laroche said his family wasn't able to get the free vaccine on Tuesday evening because the Nepean location ran out. He said they were told to phone back on Wednesday morning.

The father said no one in his family is showing any symptoms, and they're choosing to get vaccinated as a precaution.

Booster shots 6 months later

The vaccine can be used to prevent illness if given within two weeks of exposure to the virus.

Hepatitis A vaccines also require a booster shot six months after the original one. Costco Canada says it will offer boosters free of charge in six months to those who came in for the original shot.

Costco tracks what products its members buy and has twice reached out to anyone who bought the affected berries.

Both Ottawa Public Health and Santé Outaouais, the public health agency that includes Gatineau, said there have been no reported cases of hepatitis A linked to the recall.
