Ireland's third-largest supermarket chain, SuperValu, said its refrigeration systems limited to a specific model in 13 of its 223 stores had been affected by a cyber incident.
Chilled and frozen products have been removed from sale, it added.
Sweden's cyber security centre said it was responding to several incidents in ICA and Co-op grocery stores, that had caused freezer temperatures to rise sharply overnight on Monday.
Meanwhile, fridges and freezers in dozens of stores across Belgium and Luxembourg operated by Ahold Delhaize were also hit by a cyberattack, the Belga news agency reported.
Carrefour said 15 out of its 700 shops in Belgium suffered problems, and five Spar stores operated under the Colruyt Group in the country also had their fridge systems attacked.
IKEA said that one of its outlets in Belgium had been impacted, but it could not rule out more being affected.
Belgium's prosecutor's office has opened a criminal investigation into the wave of attacks targeting supermarkets in the country, a spokesperson said.
Danish engineering company Danfoss said that 17 outlets in the Netherlands were impacted by the hacking, Dutch news site Nos reported.
An unspecified supermarket chain in Estonia was also affected, with temperatures set to 50C, technology supplier Kitman Coldtech told public broadcaster ERR.
The incidents come less than a month after a similar attack impacted hundreds of supermarkets in France, during which temperatures in some fridges rose to 50C and sparked fires.
Les Mousquetaires, which owns retailer Intermarche, said that approximately 150 of its stores were affected, with the retail group forced to dispose of all the food.
Last month, Monoprix said that about 5% of its 490 French stores, and Ahold Delhaize also took several systems offline as it contended with a "security issue" in its network.
A European Commission spokesperson said the wave of incidents highlighted the importance of cybersecurity across the bloc.
The EU Food Commissioner said that supply chains should be able to withstand and respond to cyber threats.
Though no one has claimed responsibility for the attack, the cases have put a spotlight on rising anxiety among regional
authorities over hybrid attacks spreading from conflicts after Russia's 2022 invasion of Ukraine.
Moscow has repeatedly denied involvement in any sabotage or hybrid warfare operations.
'Everything is destroyed'
On Monday, one Swedish store said in a social media post that the temperature of its refrigerators and freezers had been set to 50C - echoing the incident in France.
At an ICA Baronen store in Stockholm, a notice said all the shop's freezers were broken due to a cyber attack.
Engla Ingwall, sales manager at an ICA franchise store in Stockholm said the attack occurred at 2am local time and was first noticed at 5.30am.
"There has been a cyberattack and all our freezers reached 50C," she said.
"Everything is destroyed."
Co-op told Swedish daily newspaper Aftonbladet that six of its stores had been affected by similar incidents.

The retailer did not immediately respond to a request for comment.
Sweden's national cyber security centre head John Billow said the agency was investigating the latest incidents.
The CEO of Belgian refrigeration company Sabcobel, Stephan Moelans, which operates Delhaize's systems, confirmed the incident was a cyber attack.
He said the incident unfolded when the units' evaporators were switched to defrost mode.
Luc De Laet, founder and owner of Belgian butchery chain De Laet & Van Haver, said he was woken at 3:30am by an employee telling him there was a problem.
He rushed to his store in Hove, south of Antwerp, and found the fridges turned up as high as 18C - ruining about €15,000 (£12,540) worth of meat.
"It's very scary. They are hacking the system that is doing the registration of the temperature, and they can program it at
a distance," he said.
Advances in technology have meant that devices ranging from refrigerators to heating systems that were manual, can now be controlled and monitored remotely.
This has created new opportunities for cyber criminals.
Tom Hegel, a researcher at cybersecurity firm SentinelOne, said that attacks were usually extortion, politically motivated
or nation-state level operations, with the lack of financial demands in the recent supermarket cases pointing to sabotage.
"Retail is an easy target because retail chains run enormous estates of refrigeration controllers, building management
systems, door access panels and point-of-sale gear," he said.
"Grocery margins are thin and stock perishes within hours, so any disruption hurts quickly and in public."
Authorities have not indicated who could have been behind any of these incidents.
Sandie Peggie accused the union of failing to support her during a row with her employer NHS Fife.
She previously brought a case against NHS Fife after sharing a changing room with transgender medic Dr Beth Upton at Kirkcaldy's Victoria Hospital in December 2023.
In December 2025, a separate tribunal awarded Ms Peggie a partial victory, upholding claims of harassment against her employer but dismissing allegations of discrimination, indirect discrimination and victimisation.
Her case against the RCN was heard at an employment tribunal in Dundee in September and October this year.
Ms Peggie accused the union of failing to advise her properly when she raised the changing room issue with one of the RCN's officers.
She alleged that the union had refused her request for legal assistance in relation to her claims against NHS Fife, and said it had failed to seek assurances from NHS Fife on its policies on single-sex spaces.
On Monday, all three of Ms Peggie's claims against the union were dismissed.
Employment Judge Melanie Sangster said: "The Tribunal concluded that the complaints of direct discrimination, to the extent that they were framed as being because of an asserted belief of the respondent, could not succeed."
Ms Peggie's lawyer Naomi Cunningham said the RCN was in the grip of "gender ideology" in her closing speech to the tribunal.
She claimed this made it impossible for its officers to act "vigorously" on the nurse's behalf.
A spokesperson for Ms Peggie said the judgment "makes worrying reading for all trade union members".
They went on: "It raises serious questions about the value of trade union membership if, when members report workplace concerns, the responsibility falls on them, rather than on experienced and trained union officers supported by internal and external legal teams, to identify the correct statutory basis for potential legal claims."

An RCN spokesperson said: "The judgment is comprehensive and we welcome the decision that we did not discriminate against our member based on her protected beliefs.
"RCN staff followed agreed processes that apply to all members and we acted fairly and impartially.
"We are sorry these matters were aired before the Tribunal. The RCN is an anti-discrimination organisation, supporting all of its members."
A letter has been sent by FIFA secretary general Mattias Grafstrom to council members as the deadline was reached for the governing body to respond to a series of questions about the controversy from UEFA, which is pushing for Gianni Infantino's departure.
It is understood council members will have access to "key documents" only in person at FIFA HQ in Zurich.
UEFA has sought all documents on the abandoned FIFA Forward Enterprise (FFE) scheme, saying it could pursue a case against Mr Infantino for criminal mismanagement in Switzerland, alleging he undersold the tournaments for personal financial benefit.
Mr Infantino planned the project in secret with a small group of advisers and investors, bypassing FIFA's normal governance processes and failing to consult FIFA's Council, regional confederations or member associations, UEFA has alleged.
In response, FIFA accused European football's governing body of "harassment", and trying to influence FIFA's presidential election by "spreading misinformation".
That election takes place in March, when Mr Infantino will try to be re-elected for another term.
The football associations of England, Scotland and Wales are among those which have withdrawn their support for the embattled chief, along with UEFA itself, although it has not nominated an alternative candidate, ahead of the deadline later this month.
In September, Sky News revealed that UEFA and CONCACAF (Confederation of North, Central America and Caribbean Association Football) wrote to Mr Infantino claiming FIFA's reserves are set to rise to $6bn (£4.5bn) - highlighting FIFA's financial strength despite its president claiming private equity from the scheme was needed to fund football development.
Last month, UEFA sent a list of 42 questions to FIFA, demanding answers about Gianni Infantino's alleged "conflicts of interest" over business dealings with the Trump family and the World Cup sell-off attempt.
UEFA wrote: "A series of decisions, transactions and interventions involving the FIFA President, the President of the United States and individuals associated with him raise serious questions concerning potential conflicts of interest, transparency and institutional accountability."
The letter pointed to concerns about Mr Infantino's discussions with Donald Trump and associates over the creation of a FIFA cryptocurrency, as Sky News revealed in February.

UEFA also demanded answers on, among other matters, the cancelling of US striker Folarin Balogun's red card at the World Cup after the two men spoke, creating a FIFA Peace Prize for Mr Trump without the FIFA Council's approval and FIFA's $75m (£57m) investment in Palestine during Mr Trump's Board of Peace meeting in February without the FIFA Council or finance committee's approval.
It called for a "genuinely independent investigation" into the World Cup sell-off that was abandoned by Mr Infantino after a backlash led by Europe.

The environmental group said its action off England's eastern coast was to prevent "bottom trawling" - a method of fishing in which gear is dragged across the seabed to scoop up fish.
Activists deployed the boulders, which weigh up to two tonnes each, onto the seabed at the weekend in the Southern North Sea Marine Protected Area, which is designated to protect harbour porpoises.
Greenpeace said analysis shows that in 2025, bottom trawlers logged more than 37,000 fishing hours in the protected zone, far more than in any other offshore marine protected area.
The campaigners said bottom trawling destroys delicate seafloor habitats, depletes key fish stocks the porpoises rely on and disrupts their ability to hunt.
Greenpeace claims to have effectively closed 44 sq miles (116 sq km) - roughly an area the size of Newcastle - of the marine protected area to bottom trawling in what they have declared as an "ocean park".
Actors Simon Pegg and Benedict Cumberbatch signed their names to the boulders, "marking their wish" for proper protection of such marine areas, said the group.
Greenpeace vessel the Arctic Sunrise will patrol the area to deter other types of destructive fishing over the coming days.
The Southern North Sea supports nearly 20% of the UK North Sea population of harbour porpoises, Greenpeace added.
Will McCallum, co-executive director of Greenpeace UK, said the campaign group warned the government in June to take action to protect the seas.
"Now we're setting a bold challenge to ministers - ban destructive fishing across all our protected waters at home, and lead the charge for a network of global ocean sanctuaries right across the Atlantic," he added.

Labour MP and former climate minister Kerry McCarthy, who also signed one of the boulders, said: "Industrialised fishing is having a hugely destructive impact on our marine environment, yet less than 1% of our seas are protected from it.
"We need a ban on bottom trawling and properly protected ocean sanctuaries, both here in UK waters and right across the Atlantic Ocean."
