What is the proper halachic way of disposing finger and toe nails? I heard somewhere that some people burn or bury them... Is it permissible to just flush them down the toilet or throw them in the garbage? Can you please give me the source of this halacha? thank you!!

The proper halachic way of disposing finger and toe nails is to burn them or to flush them down the toilet. It is not good to bury them as it is written that a pregnant woman might pass over them and might have a miscarriage. Sources: Moed Katan 18A and Shut Mishne Halachot Tanina P5.
