It seems they’ve having some trouble with the Holy water over in the Russian city of Irkutsk. Some 117 people, including 48 children, have been hospitalized with intestinal pain after consuming water they believed to have been made Holy by mere virtue of the date they drank it on:
Salovarov said 204 people required some medical treatment after consuming the water, the source of which was a stagnant lake. He said, however, that it was too early to say what caused the illness.
Many Russians consider any water obtained on Epiphany — which they celebrate on Jan. 19 — to be holy.
You can consider it to be whatever the hell you want, but if you drink water from a stagnant lake you should expect to end up visiting the doctor’s before too long. I guess God must have been busy elsewhere and forgot to purify the water ahead of time.
That said, the article also mentions that even the tap water in Russia is undrinkable in many places so I suppose they’re screwed either way.
