Delhaize confirmed about forty stores are hit, in both Flanders and Wallonia. Tips name Leuven and Namur, and a butcher in Antwerp also raised the alarm.

Freezers climbed to about 15 degrees in some shops, and managers called in refrigerated trucks to save stock. HLN reported far higher readings that the chain could not confirm.

Delhaize calls it an IT incident, and says it is examining how the stores can be made operational again. The butcher De Laet and Van Haver said its settings were changed from outside, though no source says who did it. Some reports link it to the French hack, but no cause is confirmed.
