Can moldy boards that have not been used for a long time really cause cancer?

Moldy boards that have not been used for a long time are thought to be carcinogenic because of the aflatoxins that can cause cancer. However, this statement is actually alarmist, and it is not.

Popular aflatoxins

Aflatoxins are metabolites of Aspergillus flavus and Aspergillus parasiticus, and are also the most toxic mycotoxins and a class of mycotoxins that are extremely harmful to human health. Its toxicity is much higher than cyanide, arsenide and organic pesticides, its greatest harm to the human body is the destruction of liver tissue, if a small amount of continuous ingestion, can cause chronic poisoning, cause fibrous lesions, and when the human body intake is larger, acute poisoning can occur, acute hepatitis, hemorrhagic necrosis, liver cancer and other fatal diseases.

Mold, long boards,It doesn't have to be Aspergillus flavus

Cutting boards are indeed prone to mildew in a humid environment, but in fact, cutting boards cannot provide a suitable growth environment for carcinogenic aflatoxins, and not all aflatoxins can produce toxins. Aflatoxins may occur in moldy corn, peanuts, and wheat. Most of the molds we see in our daily life are not Aspergillus flavus, they are actually a relatively common microorganism in nature, and if not treated cleanly, they may cause digestive diseases such as diarrhea.

How to maintain the board

Generally, wooden boards can be used for about 3 years, and the boards with serious scratches are easy to hide dirt and difficult to clean, so they should be replaced as soon as possible. If possible, you can prepare two chopping boards, and use raw and cooked food separately. In order to reduce the growth of mold, the board should be cleaned in time after use, and when cleaning the board, you can add an appropriate amount of white vinegar or salt with water, and after cleaning, dry in a ventilated and dry place.

There are many kinds of materials on the market, and we can also choose plastic, bamboo that is not easy to absorb, etc.

In order to avoid accidental ingestion of aflatoxins in daily life, we must buy food from formal channels, quality and safety are guaranteed, and most importantly, we must say no to moldy and spoiled food!

Yes. Because mold on the cutting board can lead to the growth of many bacteria as well as various viruses. Repeated use of such boards will allow these viral diseases to enter the mouth.

It can really cure cancer, and a mold called aflatoxin will grow after the board is moldy, which can induce liver cancer.

Yes, you can. The mold on it can produce many kinds of carcinogenic cells in the human body. Therefore, once the board is moldy, do not use it.

1. It's best not to use it.

2. The board is easy to mold when placed in a too humid environment for a long time, and a large number of molds and microorganisms will breed on the board after mold, especially aflatoxin, which has a certain toxicity. If you continue to use this moldy board to cut vegetables, the harmful substances such as aflatoxin on the surface will be adsorbed to the food, and it will be more harmful to health after eating, so it is not recommended to continue to use it once the board is moldy.

Mould on cutting boards is a carcinogen.

The long-term use of cutting boards at home will produce a large number of bacteria, one of these bacteria is called aflatoxin, aflatoxin is defined by the International Health Organization as a first-class carcinogen, and it is very toxic and carcinogenic.

Moreover, aflatoxins are resistant to high temperatures, and it is difficult to eliminate aflatoxins on cutting boards or dishes at home. Therefore, experts suggest that kitchen supplies such as cutting boards and tableware should be rinsed with hot alkaline water when cleaning, which can effectively kill bacteria.

Protection of cutting boards

After the traditional cutting board is used, it is scrubbed with a hard board brush and clean water to wash off the dirt along with the wood chips. If there is a fishy smell of fish, meat, etc., you can use salt-dissolved rice washing water or washing spirit to scrub, and then wash it with warm water. Do not scald it with boiling water, because the protein in the meat remains on the cutting board, which solidifies when it is hot and is not easy to wash.

After washing, stand up to dry.

After the bamboo and wood cutting board is used for a period of time, you can use a kitchen knife to scrape the sawdust on the cutting board, or use a woodworking planer to plan, so that the dirt on the cutting board can be completely removed, and the cutting board can be kept flat and easy to use.

Chopsticks and cutting boards are susceptible to mold in humid environments, but in reality, carcinogenic aflatoxins are most likely to grow on rice, peanuts and corn, and chopsticks and cutting boards are not the best choice for koji mold.

First of all, fungi are one of the most common microorganisms in nature, and most of them do not affect health.

Secondly, there are many types of fungal contamination, but not necessarily aflatoxins.

Thirdly, mold can cause food to rot, but it will not damage the body itself.

Mold on cutting boards and chopsticks is actually more common. This is especially the wet season in the south. If you pull out a cutting board without going to the kitchen on the weekend, it can be moving.

Aflatoxins (AFTs) are difuran cyclic toxins produced by certain strains, such as Aspergillus flavus and Aspergillus parasiticus. There are about 20 derivatives, named B1, B2, G1, G2, M1, M2, GM, P1, Q1, toxic alcohol, etc. Among them, B1 has the highest toxicity and carcinogenicity.

Small amounts of toxins can be detected in liver, kidneys, muscles, blood, milk and eggs after animals consume aflatoxin-contaminated feed. Aflatoxins and the bacteria they produce are naturally widely distributed, some strains produce one or more types of aflatoxins, while Aspergillus flavus also contains strains that do not produce any type of aflatoxin. Aflatoxins are mainly contaminated with cereals, oils and fats and their products, and various animal and plant foods can also be contaminated.

In order to reduce the growth of fungi, it is necessary to maintain ventilation, avoid stagnant water, and clean and dry on time. When cutting and sharing cutting boards at home, it's easy to get cross-infections and parasitic infections, so you'll need to store, label, and distinguish between the two cutting boards at home.

Usually, a wooden cutting board can last 2-3 years. Scratches should be replaced as soon as possible, because scratches or scratches are easy to hide, so they are difficult to clean and not easy to use for a long time, so cutting boards need to be replaced for up to 3 years, so they are not suitable for long-term use.

Cutting boards and chopsticks in the kitchen are related to the safety of the dining table, so they are in the spotlight. We often see reports that the chopsticks on the chopsticks at home have not been replaced for a long time and are contaminated with Aspergillus flavus, so the whole family suffers from cancer ......

Some ** said: "Chopsticks or chopping boards will breed all kinds of mold after a long time, and mild ones may lead to infectious diarrhea, vomiting and other digestive diseases." Severely moldy chopsticks and chopping boards can breed 'aflatoxin', which has been widely recognized as a cause of liver cancer.

"One family unfortunately got cancer, and the reason was that their chopsticks and chopsticks had not been replaced for a long time and were contaminated with Aspergillus flavus." ”

Is mildew a Aspergillus flavus contamination? If you have Aspergillus flavus, will it definitely cause cancer? Is it really that scary? Don't be afraidIt's not that easy to produce toxins

First, mold is one of the most common microorganisms in nature, and the vast majority do not affect health.

Second, there are many types of mold contamination, and it is not necessarily the turn of Aspergillus flavus.

Thirdly, mold often causes food spoilage, but it does not inherently cause spoilage to the body.

Aspergillus flavus is a type of mold that requires certain conditions for it to produce toxins. For example, the temperature of more than 20 degrees, the humid environment, the right nutrition. Aspergillus flavus prefers rice, wheat, corn, peanuts, etc., and generally chopsticks and chopping boards will not have such rich nutrients, and it is not so easy to produce toxins.

There are many kinds of mold contamination in life, among which Aspergillus flavus has indeed been proven to cause cancer. It's just that most of the mildew that occurs in our lives is not Aspergillus flavusIt will not cause so much harm to human health. But,Try not to touch moldy things!

Chopsticks Safety Instructions:

1.Don't rush to put the chopsticks in the chopstick box after washing them, and drain them slightly.

Did you never wash it at all? Or have you never cared about how to deal with moldy cutting boards?

What should I do if the board is moldy?

1. Do not use a steel brush to scrub the cutting board when cleaning the cutting board, whether it is wooden, bamboo or plastic and other materials, do not use a steel brush to scrub the cutting board, the steel brush scrubbing will make the surface of the cutting board rougher, so that it is easy to hide bacteria or absorb more water. The best thing is to scrape with a kitchen knife so that the surface of the cutting board is not rough.

2. After use, the cutting board is generally washed with dish soap, and then scalded with boiling water, which can play a role in sterilization. Of course, it is best to use white vinegar, which can play a good role in sterilization and deodorization.
