Reply To: Fish and meat

I thought I remembered something on this. I took a peak at my darchei halacha cheat sefer from my semicha days. He has a whole pilpul on bittul sakanah lechatchila. He has a pischei teshuva and s shu”t shoel umeishiv on th allowed side, and a yad yehuda on the assur side. He is machria that by a doraysa like fish-meat (not sure why this is deoraysah but I read it quickly as I was in a rush) we should be machmir and by a derabanan like mayim giluim (again, not sure why this is derabanan) we can be meikel. Good question to ask my lor.
