Kebab meat sold by Norwegian group Kuraas to restaurants contained between five and 30 percent pork even though it was marked as halal, the agency found.
“We will file a complaint against the producer,” Catherine Signe Svinland, an adviser at the food safety watchdog, told AFP.
“In a halal product, there should be no pork at all and when we find such quantities … we don’t believe it’s an accident but it is in fact fraud,” she said.
The group denied any wrongdoing, Norwegian media reported.
“We buy huge quantities of halal meat and we can show invoices corresponding to what we bought and sold,” marketing manager Kenneth Kuraas told news agency NTB.
“Pork ending up in these products is simply due to routines not being followed,” he added.
The Food and Safety Authority also said it had found more than 60 percent pork in pizza meat sold by another Norwegian company.
