SUPERMARKETS have urged customers not to panic buy in response to reports of emptying shelves, saying they are continuing to receive regular deliveries.
The UK's biggest supermarkets described any shortages as "patchy" across stores but said there was no need for customers to change their shopping habits.
They said any gaps on the shelves were temporary as they awaited deliveries, and were occurring in pockets rather than across supply chains.
The "pingdemic", the shortage of HGV drivers and the hot weather were all contributing to delivery glitches, grocers said, while stressing to consumers that panic buying would create a problem that did not exist.
A Co-op spokesman said: "We are sorry that we are running low on some products. Like many retailers, we are impacted by some patchy disruption to our deliveries and store operations but we are working closely with our suppliers to get re-stocked quickly."
A Sainsbury's spokeswoman added: "We are working hard to ensure customers can find what they need.
"While we might not always have the exact product a customer is looking for in every store, large quantities of products are being delivered to stores daily and our colleagues are focused on getting them on to the shelves as quickly as they can."

Tesco confirmed that it had plenty of food and deliveries arriving across the UK every day.
However, sporadic disruption from the industry-wide shortage of HGV drivers and an increase in staff self-isolating on a precautionary basis was leading to pockets of temporary low availability across a small number of products.
Iceland managing director Richard Walker has said staff absence rates are now double the usual number, with the figure rising 50% "week on week" due to people being told to self-isolate by the NHS app.
He told the Radio 4's Today programme: "We've now got over 1000 staff off, who've been pinged. That's double the normal rates, and it's rising at 50% week on week.
"Our big concern is that we've kept all of our shops open throughout the pandemic, but now we have had to close one or two shops and reduce hours in others.
"But that could get a lot worse a lot quicker, unless the country's system is sorted out."
Walker urged shoppers not to panic buy, saying: "There is certainly no problem with supply of stock.
"Panic-buying is only an option for those who can afford it and it often means that others go without."
Sandwich chain Pret A Manger has temporarily closed 17 shops due to staff being forced to self-isolate.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
