The unidentified man bought the sausages in the northern ski resort of Are and found that the meat content was labeled as 104 percent, The Local reported, citing a story in Aftonbladet.
He was told more meat is needed to make the sausage than ends up in the product, but he was not satisfied.
The customer wrote to the consumer agency: "Personally I can't accept that anything contains over 100 percent. And this sausage couldn't possibly contain more than 100 percent meat as there are other ingredients stated on the label."
Sausage-maker Trangsvikens Chark acknowledges the labeling can be confusing.
CEO Marcus Farnstrom told the local newspaper Lanstidningen Ostersund it actually means 104 grams of meat goes into every 100 grams of sausage.
"Of course there is a different way to declare the ingredients and perhaps that is what we're going to have to do," he admitted.
