There seems to be various info on anisakis on the internet. Some sites says it dies by itself in a few weeks like you say, but others say they donīt. Also I have read that people have died from this infection, which doesnīt support the sites saying it only stays in the intestines (sometimes muscles). Most other worms donīt just die that fast though! A bit confusing. One site said albenza canīt kill them, again contradictary.
