Morrisons has issued an apology to its customers following a lack of meat and lettuce found on store shelves at the weekend.
The British supermarket chain said that a disruption in their supply chain led to "low availability" on their stock levels this Saturday.
One of the supermarket giant's UK branches had to issue customer information notices in-store to explain to customers why some of their lettuce, meat and poultry aisles were reduced.
The notices read: "Due to disruptions within our supply chain, we are seeing low availability on lettuce.
"Apologies for any inconvenience caused and thank you for your understanding."
A disgruntled customer affected by the shortages told Hull Live : "You'd expect the big supermarkets to have this sort of stuff in stock. It's worrying that they can't even get the basics like salad and chicken in.
"It's not the end of the world but when you're turning to frozen and tinned items instead it really says something about where we're going. Whatever the issue is it needs sorting."
The Ukraine war and a number of other crises, including flooding in Spain, have raised fears of food shortages. Last month the government reassured the public that action was being taken to reduce the impact on food supply chains caused by the Ukraine crisis.
The country was one of the largest exporters of wheat to the world prior to the conflict. Co-op's boss also commented on the chain's difficulties in sourcing lettuce, as well as vegetable oil and rapeseed oil.
While oil shortages were due to the Ukraine war, recent floods in Spain have been blamed for the reduced lettuce supplies. Last month, The Grocer magazine warned Spanish strikes were increasing pressure on supplies of fruit, veg and salad.
Spain is a key supplier of fresh produce to the UK but has suffered a spate of bad weather and transportation issues, reports Grimsby Live.
Morrisons has been contacted for comment.
