Some supermarkets such as Waitrose have run out of stocks of the vegetable and it is understood yellow peppers are in particular short supply.
Peppers have become the latest vegetable to run in short supply following cold weather in Spain.
Morrisons has rationed sales of the vegetable to two per customer, but it is hoping to lift this in the next week or so because supply has improved.
Supermarkets such as Waitrose have run out of stocks of the vegetable in some stores and it is understood yellow peppers are in particular short supply.
It comes after peppers and other vegetables such as tomatoes were rationed by supermarkets in February due to poor harvest in the European country.
An industry source told The Times: ”Spain is key for supplying British retailers during winter, and almost every retailer in the UK will source peppers from here.
”They need warmth and light to develop – green into yellow then into red.”
The British Retail Consortium said: ”As with the tomato and cucumber shortages, retailers blamed extreme weather in Europe rather than Brexit.
“Difficult weather conditions in the south of Europe and northern Africa disrupted harvest.”
Due to the crisis earlier this year some supermarkets including Asda and Morrisons restricted shoppers to buying a maximum of three packs of vegetables like tomatoes, peppers and cucumbers.
But restrictions were lifted weeks later after supply problems that caused food shortages eased.
Last year UK farmers warned there could be pepper and cucumber shortages might happen in the spring because supermarkets were not paying enough to grow them.
The Lea Valley Growers Association, which produces three quarters of Britain’s cucumbers and peppers, said 40 of its 80 members opted not to plant vegetables over concerns they would make financial losses.
Ten of the growers who did not plant the vegetables also left the business.
The group’s secretary Lee Stiles previously told The Times that he predicted shortages of British produce in 2023 ”across the board”, adding: ”Backing British growers by paying fair prices doesn’t seem to be a priority for supermarkets.’
”The amount of British fresh produce on the shelves from our growers has reduced by at least half this year already but consumers haven’t noticed it, or don’t care.”
