Morrisons and Aldi stores in Brecon have introduced max caps on some fruit and vegetables in their stores due to difficult weather conditions in the South of Europe and Northern Africa.
Morrisons have introduced a max cap of two items per customer across tomatoes, cucumbers, lettuce and peppers.
The supermarket chain has said that they are supportive of the British Retail Consortium (BRC) line.
Andrew Opie, Director of Food & Sustainability at the British Retail Consortium, said: “Difficult weather conditions in the South of Europe and Northern Africa have disrupted harvest for some fruit and vegetables including tomatoes and peppers.
"While disruption is expected to last a few weeks, supermarkets are adept at managing supply chain issues and are working with farmers to ensure that customers are able to access a wide range of fresh produce.
"In the meantime, some stores are introducing temporary limits on the number of products customers can buy to ensure availability for everyone.”
Aldi has said they are introducing temporary limits on peppers, cucumbers and tomatoes.
An Aldi spokesperson said: “We are limiting purchases of peppers, cucumbers and tomatoes to three units per person to ensure that as many customers as possible can buy what they need.”
