Has strawberry become the most "dirty" fruit? Experts pointed out that there is no unsafety
Now is the season to eat strawberries, but a few days ago there was a news on the Internet: The United States Environmental Working Group (EWG) recently released the list of the most “dirty†and “cleanest†fruits and vegetables. For the third consecutive year, the strawberry has become the “most Dirty fruits and vegetables topped the list, followed by spinach, nectarines and apples. In the test, as many as one-third of the strawberry samples contained 10 or more pesticides, and one of the samples measured 22 pesticide residues. In addition, 97% of spinach samples were found to have residual pesticides. The cleanest fruits and vegetables are avocados, and less than 1% of the samples tested for pesticide residues.
Looking at this news, people can't help asking, is strawberry really the most "dirty" fruit? Can we still eat strawberries?
How are the most dirty fruits and vegetables selected?
According to reports, the list of the most “dirty†and “cleanest†fruits and vegetables was produced by the EWG according to official data on pesticide residue testing issued by the United States Department of Agriculture (USDA) and the US Food and Drug Administration (USFDA). Wang Yan, a deputy manager of a food and agricultural project of a well-known environmental organization, said in an exclusive interview with a reporter from the Science and Technology Daily that the US Department of Agriculture and the Food and Drug Administration publish annual inspection data two years ago. Therefore, the annual list is actually two. Years ago. The latest list is based on the analysis of 38,800 non-organic fruits and vegetables in 2016.
Dr. Yun of Food Engineering inadvertently pointed out that the EWG is an environmental organization in the United States and is called the "Environmental Working Group." They are neither government administration agencies nor academic institutions. They are just private institutions advocating environmental protection.
"Discriminating the dose to talk about toxicity is to run a rogue."
Why are there more strawberry pesticide residues than other fruits? According to the EWG report, in order to be able to produce strawberries all year round in a cheap manner, fruit growers often use toxic gases to kill weeds and all living things in the soil before planting strawberries, and use a large number of pesticides to control the pests and diseases during strawberry growth, resulting in strawberries. The situation of mixed pesticides is serious.
Does this mean that we cannot eat strawberries from then on?
Yun unintentionally stated that the criteria for determining whether or not fruits and vegetables are safe is not whether “pesticides are detected†or “how many kinds of pesticides are detectedâ€, but whether “excessive detection of pesticide residue is exceededâ€. Because the ability to detect pesticide residues is closely related to detection technology. Many of today's detection technologies are extremely advanced, and trace amounts of pesticides drifting from distant water and air may also be detected. The detection of residue does not mean that these foods are harmful to the health, and it is completely meaningless to leave the pesticide residues and control standards to discuss harm.
“Everyone doesn’t have to panic when they see this data.†Wang Xi said that the data released in 2016 is now published. In fact, we have already eaten a lot of strawberries. As long as there are no pesticides that exceed the daily allowable intake or acute reference dose (ARfD), the risk of acute poisoning is not high.

How to clean strawberry cleaner
1. Do not remove the pedicle before cleaning, so as to avoid pesticide residues on the surface of the strawberry from entering the fruit during the cleaning process, causing pollution;
2. Rinse with running tap water for a few minutes. Remember not to soak in clean water to prevent pesticides from dissolving in the water and then being absorbed by the strawberries.
3. After rinsing the strawberry, immerse the strawberry in Taomi Shui or dilute salt water for about 5 minutes. The Taomi Shui is alkaline. It can degrade and neutralize the pesticide components on the surface of the strawberry. The dilute salt water can change the osmotic pressure of the microbial bacteria. To a certain bactericidal effect.
Although a certain degree of cleaning, peeling and cooking can reduce pesticide residues by 30% or even 60%. However, Wang Hao pointed out that to completely avoid the risk of pesticide residues, the most effective way is to choose organically grown foods.
