What I thought after investigating pesticides used in strawberries

I send out life hack information such as healthcare and promote the metabolism of common sense! His main book is " Let's metabolize common sense of health! "

Good evening is Yuya @survey personality. I was researching variously about agricultural chemicals for the publication of the book today, but I saw the story that the pesticides of strawberries were going to be yaba in this. This time, I will introduce the temporary information that I worked hard to investigate about strawberry pesticides and what I felt at this time.

Strawberry pesticide ranking no. 1 in 2021 is strawberry

First of all, when I first examined pesticides, I learned that an american non-profit environmental protection group called The Environmental Working Group (commonly known as EWG) is published every year as a "dirty dazun" by examining the pesticide residue rankings. When I saw this, I learned that strawberries have continued to protect the istst place in the last six years. Are you so bad at strawberries? So what kind of pesticides are used, what symptoms are there for the damage, and what measures can be taken? I examined the contents such as.

Pesticides used in strawberries

As a result of examining it, the pesticide yaba guy used in strawberries was a pesticide called neonicotinoid system. Poisoning with pesticides is divided into acute poisoning that is exposed in large quantities in a short period of time, such as direct inhalation, and subacute poisoning caused by repeated exposure over a period of about 1 to 3 months. I thought that ordinary people would not be acutely poisoned unless they run a strawberry farmer or ate strawberries at a strawberry farm by strawberry picking, so I examined what symptoms subacute poisoning occurs once. The main symptoms of neonicotinoid subacute poisoning include central nervous system symptoms such as headache, general malaise, sleep disorders and memory disorders, skeletal muscle symptoms such as stiff shoulders and convulsions, cardiovascular and body temperature symptoms, and most patients have electrocardiogram abnormalities (reference). I thought that it would be quite unpleasant if it became this, but in the first place, japan doesn't matter because it's the worst pesticide ranking of this strawberry and it's american story, right? It seems not to be such a story apparently when thinking like the fire on the opposite bank and examining it.

Is strawberry pesticides bad in Japan?

Looking at the survey results of The Four-Leaf Co-op, it seems that the pesticide residue standard of the neonicotinoid system in Japan was set very low.

  • 60 times eu standard
  • Five times the American standard

However, since there was no citation, etc., I did not know whether this was true or not, so I decided to determine the standards of the Neonicotinoid system in Japan through the pesticide residue standard search system of the Japan Food Chemistry Research Foundation. But I quit on the way because it became troublesome to examine this in each country. This is because the United States, unlike Japan, did not make standards in the white list type, and made standards with a negative list type, and it seemed that simple comparisons could not be made. If you have time, I'll try to investigate again. It is said that there is no smoke in the place where there is no fire, and I think that it is true.

How to combat pesticides in strawberries

And, when the strawberry in Japan also stood on the assumption that pesticide residues were all over, it examined it because it wanted to know what to do with the measures this time. As a method, I do not know whether it is correct or not, but about three methods were introduced.

neutralize

The first is how to neutralize. Since many pesticides are acidic, there is a high possibility that they can be neutralized when washed with weak alkaline baking soda. However, it is meaningless if this neonicotinoid system is not acidic, and the question that agricultural chemicals can be removed if it neutralizes it to begin with has arisen. On the other hand, there was a method of washing with vinegar. This might be an intention to neutralize alkaline agricultural chemicals opposite to baking soda, but it was doubtful why pesticides can be removed with it as well as baking soda. Both baking soda and vinegar are very active in cleaning, so I think there is an effective possibility.

Wash at 50°C

The second is the famous 50°C washing method. By attaching strawberries to hot water at 50 °C for about 3 minutes, both pesticides and bacteria can be removed. I haven't wondered much until now, but in fact, I wonder if pesticides will fall with this problem.

wash with a detergent to remove pesticides

This is a method of using commercialized products to remove pesticides. It seems that agricultural chemicals can be dropped with products such as veggysafe and veggy shower. However, I felt that these products were not all-round, and I was wondering if I could properly remove neonicotinoid pesticides. Is this detergent okay in the first place? I feel that there is a higher possibility that it is safer than other washing methods because it will have passed various regulations. Vegetable oil water Veggie safe [for spray washing] No need to apply Pesticide residue Preservative removal Freshness can be retained only veggiesafe Washell (wash shell) Vegetables made from scallops superior to scallops Vegetable fruit cleaning Disinfection Freshness preservation Powder Patented product 100g

Summary

This time, I examined various things about strawberry pesticides, and I felt that it was very difficult to investigate how the national standards for individual pesticides are different and what is effective measures, although neonicotinoid systems are bad in bulk. I also felt that it would be difficult to disseminate information in this field again, as I felt that disseminating information on the dangers and disseminating countermeasure information without properly organizing them would create a mislead. That's it for this time. Thank you for browsing. So, then(^^)/
