Chumra(s) of the week

• Steven I. Weiss reports that Rav Schachter has reversed his opinion on the New York bugs-in-the-water scandal and has now effectively banned unfiltered water in the areas affected. (For full explanation see Hirhurim, whose scoop it was.)
• Rav Ovadiah Yosef has banned all shavers, and recommends using scissors instead. But no one seems to be paying much attention.
