Coconut is a favorite fruit of many people. Whether it's delicious food made of coconut, or drinking coconut water directly, or eating coconut meat, it is quite delicious. However, the coconut shell is too hard to open. For convenience, pre opened coconuts are sold on the market, and consumers only need to open the packaging and insert a straw to drink after purchasing. However, recently, coconut water seems to be frequently on the hot search, which has triggered netizens' discussion of pre opening coconut. Many people said that this symptom was not an exception: "My friend vomited after drinking the deteriorated coconut water." "After drinking it, my head hurt and my stomach turned upside down." "The shelf life of coconut is very short, and the pre opening is very unsanitary." What's the matter? Why are spoiled coconuts so poisonous? Rotten coconuts can produce Pseudomonas coconutum, and the rice yeast acid produced by this bacterium is the main cause of severe food poisoning and death for diners. What is Coconut Poison Pseudomonas? How could it be so 'terrifying'? Pseudomonas coconutum is a Gram negative short-lived bacterium with two blunt segments, no spores, and flagella. It is widely distributed in nature. Pseudomonas coconutum itself is not deadly, but it can produce a deadly toxin - mycotic acid. Rice yeast acid is a kind of small molecular fatty acid with strong heat resistance. Even boiling with 100 ℃ boiling water or cooking with pressure cooker cannot destroy its toxicity. After eating, it can cause poisoning and cause serious damage to important organs such as the liver, kidneys, heart, and brain in the human body. At present, there is no specific detoxifying drug for rice yeast acid, and once poisoned, the mortality rate can reach as high as 40% to 100%. Coconut poison Pseudomonas food poisoning often occurs during the summer and autumn seasons. Due to humid and rainy weather conditions, as well as poor storage, Coconut poison Pseudomonas grows and propagates in large quantities in food, leading to poisoning. The poisoned person has symptoms of acute gastroenteritis, with clinical manifestations of upper abdominal discomfort, nausea, and vomiting 2 to 24 hours after eating. In severe cases, it appears as a coffee colored substance, with mild diarrhea, dizziness, and general weakness. Severe cases can result in vomiting, hematuria, oliguria, subcutaneous bleeding, jaundice, hepatosplenomegaly, unclear consciousness, restlessness, limb twitching, and even toxic shock, leading to death.
