What exactly is the chemical condition of food poisoning in humans?

Arsenic and Heding red are both arsenic compounds, of which trivalent arsenic ions are highly toxic, Heding red is made of arsenic red ore grinding, arsenic is processed arsenic trioxide, toxicology is to denature proteins, hehe, but, according to Moscow University research, ingestion of trace amounts of arsenic is conducive to improving intelligence, pay attention to the trace amount, you don't try it, please.

Causes of food poisoningThe causes of food poisoning include bacterial infections or bacterial toxins, and there are no viruses. If the infection is toxin, it is because the bacteria multiply in the food and produce the toxin, the patient is poisoned by eating the food, which is mainly manifested as symptoms of acute gastroenteritis but does not have fever, which is toxic food poisoning.

But if a large number of bacteria multiply in the food, mainly live bacteria,After eating food containing live bacteria, patients present with fever and symptoms of acute gastroenteritis, which is infectious diarrhea, which is infectious food poisoning。In some patients, both toxic and infectious, cause food poisoning.

Symptoms of food poisoning: Food poisoning is characterized by acute gastroenteritisSuch as nausea, vomiting, abdominal pain, diarrhea, etc., the patient begins with abdominal discomfort, followed by epigastric pain or paroxysmal abdominal cramps, first nausea, vomiting, and then diarrhea, vomit is stomach contents and bile, diarrhea varies from mild to severe, the frequency of stool is several times a day to dozens of times, stool is yellow loose stool, watery stool or mucus stool, there can also be pus and blood stool, bloody stool.

On physical examination, there may be mild tenderness in the upper mid-abdomenHyperintestinal sounds, etc., some patients may have chills, fever and systemic poisoning symptoms. People with severe vomiting may have varying degrees of dehydration and acidosisPatients with dry lips, polydipsia, poor elasticity, sunken eye sockets, etc., severe dehydration patients may have weak pulse, decreased blood pressure, shock, and electrolyte disorders, such as low sodium, low potassium, etc., and the course of the disease mostly ends within 1-3 days.

Self-help methods for food poisoning, mild food poisoning can also be dealt with by yourself**,Generally, the manifestation of mild food poisoning usually causes symptoms such as nausea, vomiting, abdominal pain, diarrhea, etc., and slightly more severe symptoms affect the central nervous system and dizziness, headache, nausea, etc.

Generally, if the above mild symptoms appearFirst of all, the food you eat should be excreted as soon as possible, if you have a stress reaction, vomiting, diarrhea, you don't need to stop vomiting for the time beingAntidiarrheal, after all the food in it is spit out or diarrhea is clean, antiemetic and antidiarrheal treatment is considered, and the food can be automatically excreted from the body.

Symptomatic treatment such as antidiarrheal and antiemetic can be treated with metoclopramide and antiemeticAntidiarrheal can be taken orally with montmorillonite powder**. If abdominal pain is severe, oral hyoscyamine can be used to relieve spasmodic pain, and antibiotics can also be used appropriately**Third-generation cephalosporin antibiotics or quinolone antibiotics are the main antibiotics. However, if there is no symptom relief or severe food poisoning symptoms appear, such as coma or shock, you must be sent to the hospital immediately for emergency treatment.

Food poisoning refers to all foods that have been contaminated with food, pathogenic bacteria, viruses, or infected with parasites, chemicals or natural toxins (e.g. poisonous mushrooms). Generally speaking, food poisoning is a disease with a rapid onset, often within a few minutes to a few hours, and mainly presents with acute gastrointestinal symptoms, such as abdominal pain, nausea, vomiting, diarrhea, etc.

Abdominal pain: Epigastric pain is common in the early stages, and mid-abdominal or full-abdominal pain may occur in the later stages, sometimes the pain is severe and unbearable.

Food poisoning.

It is a very common disease in clinical practice, mainly caused by eating expired or spoiled food, mostly caused by bacterial infection, and a few by toxic substances, such as eating food containing organic phosphorus, mercury and other elements, as well as the natural toxins of the food itself. It usually becomes ill a few hours after a meal, and if food poisoning occurs, you should go to the hospital promptly**. Food poisoning causes intestinal congestion, edema, inflammation, infection, and digestive disorders.

The onset of the disease is very acute, and the main clinical manifestations are nausea, vomiting, abdominal pain, diarrhea, etc., and in severe cases, it will cause dehydration, electrolyte imbalance and acidosis, and even life-threatening.

It is to eat some undercooked food or some poisonous food, which cannot be well distinguished, such as some wild vegetables and poisonous mushrooms. Food poisoning can cause nausea, vomiting, diarrhea, hyperactivity or listlessness, and in severe cases, coma, low blood pressure, and hypoglycemia.

Chemical food poisoning refers to the phenomenon of acute poisoning caused by healthy people after ingesting a normal amount of food that is sensory abnormal, but contains a large amount of chemical harmful substances. Chemical hazards include toxic metals, pesticides such as organophosphorus, and some chemicals such as nitrite and arsenide. Chemical food poisoning has the characteristics of rapid onset, short incubation period and high case fatality rate, and the incidence rate has been increasing in recent years.

Food contamination with large amounts of chemicals is the main cause of chemical food poisoning. Harmful chemicals that may contaminate food should be covered with metals and their compounds, such as arsenic, lead, mercury and other compounds;

pesticides such as organophosphorus, organochlorine, arsenic, etc.; veterinary drugs such as clenbuterol hydrochloride ("clenbuterol"), etc.; Toxic substances for industrial use, such as methanol delay mold, formaldehyde, etc. Most of the chemicals that cause food poisoning are highly soluble in the body and are easily absorbed by the gastrointestinal tract or oral mucosa.

There are three common types of chemical food poisoning: pesticide poisoning, methanol poisoning and nitrite poisoning.

Chemical food poisoning caused by pesticides is mainly the consumption of food contaminated with pesticides; Methanol poisoning is caused by mixing industrial methanol into grain to produce counterfeit liquor, which can cause blindness and even death.

Nitrite poisoning is poisoning caused by the accidental ingestion of nitrite. It can also be caused by the proliferation of nitrate-reducing bacteria in the gastrointestinal tract when gastrointestinal dysfunction is consumed, and nitrate is reduced to nitrite in the body when nitrate-rich vegetables are eaten, causing nitrite poisoning.

Chemical hazards in food refer to the hazards caused by toxic chemicals contaminating food, including common food poisoning. Chemically poisoned food, which usually refers to food contaminated with toxic chemicals; Food contaminated with toxic and harmful chemicals that are mistaken for food, food additives, or food nutrition enhancers; Foods with non-food grade or falsified or prohibited food additives, food nutrition fortifiers, and excessive use of food additives; Foods with chemical changes in nutrients (e.g., grease spoilage).

Various toxic chemicals enter food and make it toxic, mainly due to the serious contamination of food by these chemicals in the process of production, processing, storage and transportation.

A large number of organic compounds also enter the human environment with the chemical industry, causing widespread pollution of water, air, soil and food. Harmful feeds and feed additives used in animal husbandry are more harmful and have become an important problem in today's chemical hazards.

Among the various chemical hazards, contamination of the production process of food raw materials (pesticides, fertilizers, growth promoters, etc.) is the most important chemical hazard in food.

1) Natural toxins: including tetrodotoxin, histamine, ciguatoxin, cyanogenic glycosides, gossypol, etc.;

2) Pesticide residues: including organochlorine insecticides, organophosphorus insecticides, carbamate insecticides, pyrethroid pesticides, carbendazim fungicides, organomercury, organosarsenic fungicides and other pesticide residues;

3) Veterinary drug residues: including residues of antibiotics, sulfonamides, furans and other drugs;

4) Metals: including cadmium, lead, mercury, arsenic, zinc, etc.;

5) Abuse of food additives: including the excessive and excessive use of various food additives;

6) Food packaging materials, containers and equipment: including plastics, rubber, coatings, ceramics, enamel and other materials;

7) Radioactive contamination in food: including the hazards caused by various radioisotope contamination of food raw materials;

8) Others: including N-nitroso compounds, polycyclic aromatic compounds, polychlorinated biphenyls, etc.
