Worm in Raw Fish

Saturday morning, my wife and I went to wet market to buy fresh fish. Before noon, my wife will wash the fish and do the preparation for the lunch. As usual after the washing I will pour wine into the fish to remove the fish smell and went back to my room. My wife will later steam the fish. the moment I stepped into my room, my wife started screaming and I went back kitchen to find out what happening. She pointed at the fish and said worm. This is also the first time I saw worm crawling out of the fish. I capture the scene into my phone and started to search on the net to find out. According to the internet, this shown the fish is fresh. If the fish is frosen, the worm or parasite or Anisakis will not be able to survive.
