Nomad Foods, the parent group of the Birds Eye, Iglo and Findus brands, said frozen food businesses are getting accustomed to more than 20 percent higher sales since the surge that accompanied the imposition of coronavirus lockdowns.

"We had an extraordinary spike in the middle of March but since then people have come back to a new normal, so we are still the region of 20 percent plus," Nomad Foods CEO Stefan Descheemaeker said in a conference call discussing first quarter earnings last week.
