The trend of preparing dishes using sea water when on a boat continues on Instagram and TikTok, videos that had already sparked controversy last summer. “Taking water from the stern of a boat – where there is fuel, bilge pumps that contain oil and other materials, but also the boat’s drains with excrement – to cook pasta is stupid. Then you should not be surprised if we have problems of various kinds, I am surprised how every summer there are people who really joke with their health”, comments the infectious disease specialist Matteo Bassetti on Instagram.
