The Norwegian company had pop-up salmon hot dog stands in six different US cities - Boston, Los Angeles, Miami, Oakland, Salt Lake City, and Washington DC.
Kvarøy Arctic, which supplies salmon to Whole Foods Market and other US retailers, said it wanted to ensure voters in underserved communities had nourishment while waiting to vote.
It sited its hot dog stands near polling locations with historically long lines, predicted massive turnouts, or limited facilities.
“Since March, Kvarøy Arctic has developed a robust donation programme supplying thousands of pounds of salmon to food banks and community kitchens across the country each week,” said the company in a press release.
“This effort shed light on a harsh reality - the food system isn’t built to support the growing national need for subsidised food, including fish and seafood. It was through this realisation that Kvarøy Arctic came up with an idea to energise and support voters.
“Kvarøy Arctic believes that sustainability and the long-term health of the planet intersects with proper nutrition and social justice.”
