[Video Summary]
This video explains two major controversies surrounding "homemade enzyme juice" that occurred in the shadow of the beauty and health boom.

In 2015, the Consumer Affairs Agency, a national government agency, and in 2023, a resort hotel in Nishi-Izu, Shizuoka Prefecture, both published and offered recipes that involved "stirring with bare hands to ferment using the bacteria naturally present on the hands." These practices drew fierce criticism, forcing apologies and the discontinuation of the recipes.

Why is "stirring with bare hands" so dangerous? This article will delve into the crucial differences between this method and traditional fermented foods like fermented rice bran pickles, the terrifying mechanism of enterotoxins (heat-resistant toxins) produced by Staphylococcus aureus (a bacterium found on human hands), and the risks associated with misconceptions based on pseudoscience lacking medical evidence.

[Video Description]
In this video, we explore two major controversies surrounding the trend of "homemade enzyme juice," a fad driven by beauty and health claims in Japan.

In 2015, the Consumer Affairs Agency, and later in 2023, a resort hotel in Nishi-Izu, faced severe public backlash for promoting or serving juice made by "stirring with bare hands" to encourage fermentation using natural skin bacteria. Both parties were forced to apologize and either retract their recipes or immediately halt the service.
Why is stirring with bare hands so dangerous? We delve into the critical differences between this dangerous practice and traditional fermented foods, the terrifying mechanisms of heat-resistant "enterotoxins" produced by Staphylococcus aureus (a common bacterium found on human hands), and the hidden risks of pseudoscience lacking medical Evidence.

Ministry of Health, Labour and Welfare: Dangers Lurking in Food – Tips for Delicious and Safe Eating

This is an official educational material from the Ministry of Health, Labour and Welfare explaining the mechanism of food poisoning caused by enterotoxins, toxins produced when Staphylococcus aureus, a bacterium present on human skin and wounds, multiplies in food. Enterotoxins are not neutralized by normal heating (such as boiling) once produced. https://www.mhlw.go.jp/stf/houdou_kou...
