A very spicy cheese on sale at Morrisons is being sold with a health warning.

Cheesemongers at the supermarket are now selling Reaper Chilli Cheddar and it is made using the world's hottest chilli peppers.

The Carolina reaper is 300 times hotter than jalapeño chilli or Tabasco sauce, which is why the supermarket is warning cheese-lovers about its extreme spicy quality.

The packaging around the red cheese even includes the warning: “Caution Hot”.

The Reaper Chilli Cheddar costs £1.50 for a 120g serving. It is available over the counter at Morrisons Market Street Deli.

The supermarket is launching the Reaper Chilli Cheddar just in time for the summer barbecue season, giving its most daring customers a lot more added heat for their summer burgers.

Daniel Barrett, deli cheese buyer at Morrisons, said: “Some customers have told us that they’d love us to sell more really hot foods.

“They’ve increasingly been buying cheddars with chilli in and this is the hottest we’ve ever served.

“It is perfect on top of a BBQ burger but it’s definitely not for the faint-hearted. So we advise handling – and tasting – with care.”

Last October the supermarket launched the Volcanic Vindaloo, after chilli fans said that they needed even more heat than their usual Morrisons curry delivered.

The Carolina reaper is grown by Ed Currie of PuckerButt Pepper Company in South Carolina.

Cheese-lovers are being warned the cheese might be hotter than they can handle

According to Guinness World Records, the Carolina Reaper is the world’s hottest chilli with an average heat level of nearly 1.6 million Scoville Heat Units (SHU).

However, one of the samples tested by the food scientists at Winthrop University in South Carolina, USA, was found to be 2.2 million SHU.

A jalapeño chilli registers only 5,000 SHU on average.

The Scoville Heat Unit (SHU) scale is a way of working out a foodstuff's “spiciness”, by measuring the concentration of capsaicinoids - the chemical compounds responsible for the sensation of heat.
