I found many jellyfish at the seaside. What should I do to fry or eat cold? Do we have to use alum? Cann't you treat it with seasoning? willies

As early as the Ming Dynasty, fishermen knew that fresh jellyfish were poisonous, so they had to marinate them with salt and alum, soak them to detoxify them, and filter out the water before eating them. However, from ancient times to the present, it is not uncommon for fishermen in the seaside of South Guangdong to eat fresh jellyfish poisoning by accident because they are greedy for delicious seafood. In addition, jellyfish, like other seafood, are easily contaminated by halophilic bacteria, and eating cold jellyfish silk by mistake can cause bacterial food poisoning. A bacterial food poisoning accident occurred in a hotel in Jiangmen City, Guangdong Province, where 73 people ate cold jellyfish. Summer is the season when intestinal diseases are easy to occur and become popular. As a lesson from the past, raw jellyfish silk should be handled with care, and attention should be paid to hygiene during operation to prevent flies, dust and pollution. After shredding, it is best to rinse it repeatedly with cold boiled water and dry it to prevent food poisoning. Raw material x
