With the arrival of summer
The weather started to get hot
There have been a number of food worm incidents in various places
"I just bought the soy sauce and ate it for two days.
When I opened it, I found a lot of maggots inside,
It's really horrible! ”
Such a situation
It has not been uncommon in recent years
Let people "talk about insect discoloration"
We can find that every summer, jiangxi, Guangdong, Guangxi, Zhejiang, Hunan and other places will have a number of food insect incidents, the food range of insects covers soy sauce, sauce, fish, meals, dairy products, etc., of which the most common soy sauce in daily life, the frequency of insect phenomenon is the highest.
Who is the "culprit" who causes food worms? How can I avoid food bugs in hot weather? Recently, the Guangdong Institute of Biological Resources Application has made the latest scientific research discoveries through long-term research on flies, which often invade the kitchen, and has unveiled for the first time the truth behind the high incidence of food insects in hot summer.
Guangdong Institute of Biological Resources Application
Founded in 1958, its predecessor is the Guangzhou Institute of Entomology of the Chinese Academy of Sciences, which is a provincial public welfare first-class scientific research institution mainly engaged in the basic and applied research of animal science, and has rich experience in the study of insect life habits.

Who is the "culprit" who caused the soy sauce worm? Sauce flax fly!
In the past, it was commonly believed that food worms were flies laying eggs on food, and eggs hatched into adult worms. In fact, such an answer is not entirely accurate. According to the latest research, there are many types of flies, resulting in different types of flies that eat insects.
Qiu Xuehong: There are many kinds of flies, among which the flies, lilies, and flies are closely related to humans. In general, flies prefer to lay eggs on bran cultures or feces; lychees and flies prefer to lay eggs or insects on meat cultures. Sauce flax flies are more special, and like to produce insects in sauce products, such as bean paste, soy sauce and the like. This is also the reason why the name of the sauce flax fly has the word "sauce". The sauce flax fly has a more special "oviparous birth" method, "oviparous birth" refers to the development of young eggs directly in the mother's body, and the mother directly produces insects when it is produced. This is also the reason why we do not have a long exposure to food in our lives, and we have not seen eggs, but we find that food is full of worms.
Flax sauce flies produce insects at the mouth of soy sauce bottles with residual soy sauce
Therefore, the phenomenon of soy sauce insects occurs frequently in summer, and the culprit is this fly called "sauce flax fly", which lies in the "oviparous birth" breeding method that this fly can directly produce insects.
Can eggs hatch into adults in soy sauce?
impossible!
Some media reports have said that the soy sauce worms are because the quality management or sterilization measures of soy sauce manufacturers in the production of soy sauce are not perfect, resulting in the soy sauce itself carrying worm eggs, for a long time, the eggs hatched into worms in the soy sauce, resulting in the good end of the soy sauce after a few days of use. Is there a scientific basis for this statement?
Qiu Xuehong: The eggs of ordinary flies cannot hatch in highly salinized liquid foods such as soy sauce. The larvae directly produced by the "sauce flax fly" can survive and grow in a high-salt environment.
Therefore, the phenomenon of soy sauce insects, which is common in life, is fundamentally due to the "oviparous birth" breeding method of sauce flax flies that can directly produce larvae. While the widely suspected soy sauce itself carries fly eggs and hatches adults, it is impossible to occur. The relevant news materials also confirm Professor Yau's statement.
The phenomenon of soy sauce worming, which is widely complained about by consumers, is only produced during the use of soy sauce after it is opened. The latest scientific research has found that the two tentacles on the sauce flax fly can help the sauce flax fly quickly find foods with high protein and amino acid content. Good quality soy sauce, rich in amino acids, soy sauce after opening the use of the process, left in the bottle cap, bottle body, etc., will easily attract sauce flax flies. At the same time, the growth and reproduction rate of the sauce flax fly is also very fast, if the unopened soy sauce itself carries larvae, consumers can obviously find it with the naked eye when buying soy sauce.
In order to let everyone know more about the sauce flax fly, the institute has sorted out the archives of the sauce flax fly according to the latest scientific research findings.
How to avoid food worms?
Insect Repellent Capture!
Based on the research and analysis of the life habits of flies, Professor Yau also gave the following "insect prevention strategies":
1. Soy sauce and other sauce foods that are easy to attract sauce flax flies, after use, the bottle mouth, bottle body should be wiped clean and covered in time, and it is recommended to store the refrigerator for preservation.
2. Keep the home environment clean and hygienic, and remove kitchen waste in time.
3. Add a food cover when storing food to prevent flies from laying eggs and insects on food.
4. Meat, milk and other foods that are easy to attract flies should be placed in the refrigerator in time for preservation.
After the soy sauce is used, wipe the bottle mouth and bottle body clean in time, and close the bottle cap
Reports of food worms are frequently reported in the summer and autumn of each year, and have caused a lot of controversy. Manufacturers have manufacturers' statements, the media have media statements, there can be a hundred statements, but the truth is always only one. Do not spread rumors, do not believe in rumors, believe in science, and look at the facts with a scientific and objective eye, this is the attitude that should be treated as a consumer, as a manufacturer, or as a media, to treat facts and disputes.
