Which meats don’t have an OU?
Those under Star K, but if it’s Star S, I’ll buy it. I buy my meat from either Moisha’s/KRM, or from Glatt Mart.
I’m not makpid on chalav stam kelim. I recently adapted cholov yisroel, so in time, I’ll probably become makpid on kelim, also.
For vegetables, I tend to keep it to Postiv/Kosher Gardens, but will occasionally buy Bodek for some things.
