The presence of plastics in stomachs of seals was investigated for the first time.
In animals that died during a viral disease outbreak near the island of Texel in the Netherlands, 12% of the stomachs contained plastic, usually a single item. This of course is an alarming signal, but the frequency seems too low for a useful monitoring study like conducted by IMARES for Northern Fulmars.
