Kmart shoppers have warned about toxic Christmas-themed quilt covers they say have caused breathing problems and body rashes.

The discount retailer has issued a voluntary recall for the festive Anko-branded bedding sets, which are made in Pakistan.

They include the Mr & Mrs Claus Reversible Queen Size Bed Quilt Cover Set and Christmas Elf Reversible Single Bed Quilt Cover Set.

“We take the quality of all our products seriously and are committed to addressing customer product satisfaction issues. Regardless of whether they have experienced any issue, customers who have purchased the Mrs & Mrs Claus Reversible Queen Size Bed Quilt Cover Set and Christmas Elf Reversible Single Bed Quilt Cover Set may return the product to store for a refund,” a Kmart spokesperson told The New Daily.

“If customers have any questions, we ask them to contact Kmart Customer Service on 1800 124 125. We have taken the proactive step of notifying the ACCC of a voluntary product recall yesterday. The public recall notice will follow in the coming days.”

Media reported that customers had been hospitalised after purchasing the printed cotton covers.

The items have since been deleted from Kmart’s website.

One Facebook user posted a warning on Monday night.

“A warning to parents. My friend was hospitalised last night. She had respiratory and heart problems, caused from inhaling a chemical that is classified as a poison that was on new Christmas bedding,” they wrote.

Another anonymous customer told Yahoo she bought a set for her bed and her son’s bed.

When she unwrapped the new sheets, the Queensland mum said there was an overwhelming smell of “jet fuel”. Within days her son developed asthma symptoms.

After two weeks with the bedding, her husband woke up in the early morning suffering chest pain and was eventually hospitalised.

“He was genuinely scared,” said the woman.

She said one of the paramedics who arrived to treat her husband instantly told her to remove the blanket.

“One of the paramedics walked in and turned it over and said to get it off him,” she claimed.

“They had seen complaints about the blankets, and multiple cases with everything from rashes to chest pains and they all have this blanket. I thought that was crazy.”
