    Hello!

    Flies are known pathogens-carriers by touching food with its infected mouthpart and legs, but, as recent discovery shows, they also have antimicrobial defences on their surface.
    From these facts, it's claimed in some websites that
    it's recommended to immerse completely a fly that falls into your drink in order to counteract those very pathogens.

    Do you think this claim is scientificaly sound?

    Here's my problem with that scenario: there is a whole world inside your glass! If there is any viable pathogen on the fly (by viable, I mean it has not already been neutralized by the antimicrobial defenses of the fly) and that pathogen is transferred into the fluid of your drink, how can we say where that pathogen might get to inside your drink? Fluid dynamics tells us there are currents happening in your drink. These currents may carry the pathogen away, or if the pathogen is motile it might just swim away on its own. Now the antimicrobial chemicals from the fly are introduced by submersing the fly. How effective with that be? Will these chemicals even make contact with the pathogen? Will they be affected chemically by the liquid of your drink? My guess is that submersing the fly will not help. That said, I can't find anything about the fly's antimicrobial defenses. Do you have an article that discusses these defenses?

    Thanks for your answer!

    I think I would just throw the drink away.

    This appears to be coming from a Muslim hadith.

    Ruling of a fly falling in one

    Narrated Abu Huraira (RA): Allah’s Messenger (SAW) said, “If a fly falls in the drink (beverage) of one of you, he should fully immerse it and then remove it because there is a disease (poison) in one of its wings and cure in the other.” [Reported by Al-Bukhari and Abu Dawud who added: “It (the fly) protects itself with the diseased wing.”]

    Are you FFING kidding me? So, they threw him from a bridge with a rock bound to his legs right? Why not simply pull of 1 of the wings from a fly and watch it die from it's own poison. I bet he didn't experiment, what a great ... theoreticus.
    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    That says it all for me.

    I hear Hadith converted to christianity, because he found there were more idiots like him with ridiculous ideas to be found there, then in his original religion.

    Thanks for the link termina. Actually, that article just describes that some scientists were looking into how flies maintain their seeming immunity to all the diseases they encounter, but it does not describe their findings (and I could not find them, but maybe someone else will have better luck). I've been doing some more poking around, and as far as I can tell no one has discovered anything to lend credence to the submerged fly scenario. That, in addition to the fluid dynamics concerns I mentioned before, leads me to the conclusion that the idea is not scientifically sound.

    I would just point out that a hadith is not a person. But carry on.

    Ah... It seemed like a name to me.. Then second guess is that hadith is a muslim cult or subreligion?

    Ermm... a Koran is that holy book, while a hadith is the peoples quoting prophet Muhammad's word. Whenever a Muslims had a religious question they will refers to the Koran or to the quotes (but mostly people refer to their Imams/leader for interpretation). -The stuff about the 'fly in a drink' is from the quotes and not from the Koran.

    A sect (variant of religion) is created by interpreting those sources differently. For example: a sect called Syiah believe their imam has supernatural powers.
