Fresh Produce Journal reported that according to British Leafy Salad Growers, lettuce stops growing when temperatures reach 30°C.
According to information from Beacon supplier Ribble Farm, fresh produce products, such as lettuce, watercress and broccoli are expected to increase by about one quarter.
This is a result of the scorching temperatures the UK has recently seen, which have been having an impact on the quality of produce available and, therefore, quantity.
Rapid deterioration
Beacon said farmers are subsequently being forced to charge more for products in order to compensate for the loss of produce.
The research also suggested there were quality concerns over delicate products, including broccoli and cauliflower, due to rapid deterioration in the heat.
Beacon MD Paul Connelly predicted a possible shortage of fresh produce, but he also said it would be unlikely to affect pricing on pub menus.
Sizzling summer
He added: “Although Brits might be enjoying the hot weather, our fresh produce definitely is not.
“With suppliers noting a decrease in quality stock and, therefore, supply, prices could rise by approximately 25%.
“It is currently difficult to tell what the full consequences will be but, while it is a possibility, it is unlikely these increases will immediately impact menu pricing and be passed on to consumers.
“However, with a simple summer salad being a great dining choice in the hot weather, we may see it impact on consumers in the months to come if the sizzling summer continues, demand for produce increases and reduced supplies continue.”
