I'm not going to look this up. If anyone wants to believe that ingesting even the smallest bit of glass doesn't have the potential for serious harm, go ahead.
Glass is inert so it certainly wont poison you. Injuries from ingesting sharp glass shards are urban legends, not true medical case reports. If you filter the beer there is zero risk of harm from the glass, if you don't filter it there is really little to no risk as long as you siphon and decant it as usual. Exen if a small piece got in your glass it will sink. If somehow a piece finally got in your mouth you would notice it since your tongue and mouth is extremely sensitive to changes in texture, shape. If somehow after all this you swallowed a piece, it would almost certainly pass through you with no damage at all.
This is a definite RDWHAHB moment.
