Causes of bacterial food poisoning

2018-04-25 14:24:27

Bacterial food poisoning is mainly caused by food contamination by microorganisms such as bacteria. The hot summer provides suitable conditions for bacterial growth and reproduction. At the same time, people often due to hot weather lead to decreased appetite, lack of sleep, excessive sweating and other reasons, which lead to decreased immunity. If you do not pay attention to food hygiene, it is easy to occur bacterial food poisoning.

Methods/Steps
1

Spoiled food contains a lot of bacteria and toxins, even if cooked it is difficult to decompose the toxins in the spoiled food, eat the spoiled food is prone to bacterial poisoning, light nausea, diarrhea, heavy people may die. Especially in the high temperature season, the bacterial reproduction rate is amazing, the protein in the food is easy to deteriorate, and the shelf life is greatly shortened.

2

Do not eat food that is not cooked through. Do not covet the freshness of food. Because it is very likely that some pathogenic bacteria and parasitic eggs that have not been killed exist in food, it is easy to cause gastrointestinal infections and other diseases. Such as green beans contain saponins, is a neurotoxin, into the human body will make the nervous system first excited after paralysis, and even lead to respiratory system paralysis and death.

3

Food storage time is too long vegetables contain nitrates (non-toxic), after a period of storage, nitrate is reduced by enzymes and bacteria into nitrite (toxic substances), nitrite in the human body and protein substances, can produce carcinogenic nitrite amine substances. Therefore, fresh vegetables should be purchased in the market, and vegetables with yellowing, water stains and rot are not edible. Overnight vegetables can not be eaten, because the nitrite content of overnight vegetables is very high, and the heating method can only destroy microorganisms and bacteria, and nitrite is not heated off. The growth rate of most bacteria slows down when food is stored in a refrigerator. However, some bacteria are cold-loving, such as Yersinia, Listeria, etc., can grow rapidly at this temperature, and if you eat food infected with this type of bacteria, it will cause intestinal diseases. However, freezing does not mean that it can completely kill bacteria, and some bacteria with strong freezing resistance will survive. Therefore, from another point of view, if the refrigerator is not frequently disinfected, it will become a "hotbed" of some bacteria.

Both raw and cooked, causing contamination meat scraps contaminated tableware, fingers and food cause infection, especially when cooking and processing, both raw and cooked, causing pollution, are mainly displayed in containers after raw food, untreated, directly put cooked food. Tableware is not differentiated can also cause disease, experts recommend that the sandwich, holding raw food and direct mouth of the tableware separate. At the same time, in order to avoid cross-contamination, it is best to use serving chopsticks. Such as kindergarten food poisoning, canteen raw and cooked without causing cross infection events.

Eating raw fish such as raw aquatic products and cold dishes is also likely to cause bacterial food poisoning. Liver fluke eggs parasitic in the fish body, if you eat raw river fish, liver fluke will enter the human body to develop into an adult, can make the human body suffer from cholitis and other diseases. Some experts pointed out that common grass carp, black carp, perch and freshwater shrimp may contain liver flukes, must be cooked before eating. Eggs should not be eaten raw. The anti-biological protein contained in egg white will hinder the absorption of biotin by the human body after binding with biotin in the gut. Raw eggs also often contain salmonella bacteria, which can cause vomiting and diarrhea. There have been news reports that because of eating the restaurant's "cold whelk meat" and "spicy Fu Shou snail" after the infection of meningitis. Don't be a quick talker. Eating raw vegetables can reduce the loss of nutrients in the cooking process of vegetables, however, not every vegetable is suitable for direct raw food, washing vegetables that can be eaten raw include carrots, white radish, tomato, cucumber, bell pepper, large cabbage heart and so on. It is best to choose green or organic vegetables when eating raw. The method of eating raw includes drinking homemade fresh vegetable juice, or mixing fresh vegetables cold, can be appropriate to add vinegar, less salt. Need to blanch with boiling water to eat vegetables are: broccoli, cauliflower, spinach, bamboo shoots, water stems, kohlrabi, purslane, etc., lettuce, water chestnuts and other raw before eating is also best to peel, wash, with boiling water to eat again, so more sanitary, will not affect the taste and nutritional content. When making cold dishes, we must pay attention to the use of special cutting boards, pay attention to the cleanliness of utensils. Never mix meat and vegetable cutting boards.
