Core Viewpoint - The aftermath of Typhoon "Hagupit" has led to a phenomenon where beaches in Fujian, China, are covered with oysters, prompting citizens to collect them, raising questions about their origin and safety [1][2]. Group 1: Origin of Oysters - The appearance of large quantities of oysters on beaches after typhoons is not a new occurrence, as previous typhoons have also resulted in similar situations in Guangdong and Fujian [2] - Experts explain that strong typhoons can displace oysters and clams from marine farming areas onto the shore due to increased wave action [2]. Group 2: Health Risks of Consuming Oysters - Although the oysters may appear fresh, they can pose significant health risks due to potential contamination with harmful substances and pathogens [3] - The rapid environmental changes caused by typhoons can lead to the proliferation of bacteria and viruses in the water, making the oysters potentially dangerous to consume [3]. - Oysters can accumulate harmful substances like heavy metals and pathogenic bacteria while filtering seawater, thus becoming "biological carriers" of health risks [3]. Group 3: Safety Risks During Collection - The process of collecting oysters can also be hazardous, with risks of being swept away by waves or injured by sharp objects like glass and nails on the beach [4][5]. - Additionally, there is a risk of encountering dangerous marine life such as jellyfish and sea urchins, which can cause serious injuries [4][5]. Group 4: Ongoing Dangers Post-Typhoon - Even after the typhoon has passed, coastal areas may still experience strong winds and long waves, posing dangers to individuals who venture too close to the water [5]. - The presence of sharp objects and hazardous marine creatures in the water can further increase the risk of injury or health issues [5].
