As'salamu Alaikum dear brother,
It is always best to eat Muslim Halal or Jewish Kosher meat. Both are bloodless and have the Name of GOD Almighty invoked on them. But if you can't find either, then go for the Christians' stores and buy meat from there. Make sure you invoke the Name of GOD Almighty on your meat, which we anyway do every time before we eat even with Halal meat. Otherwise, try to eat sea food.
And Allah Almighty always Knows best.
Take care,
Osama Abdallah
