Concern About Halal Food Vendors in NYC

Asalamu Alaykum, brothers and sisters. I wanted to share a worry I’ve been having lately. I’ve been visiting several Muslim-owned halal food carts selling things like hot dogs and beef or turkey bacon. When I ask about the brands or packaging, about 90% show me products from brands like Oscar Mayer, Millers, JFM, which I’m not sure about halal certification. Only about 10% confirm they use halal-certified brands. So now I’m wondering, am I required to ask every single Muslim-owned halal cart about their products? I find myself torn between trusting my Muslim brothers and being cautious about everything. With restaurants that have certificates and visible kitchens, it’s easier to trust, but these carts seem different and harder to verify. Where should I draw the line? I’ve talked to many Muslims who say that even halal-labeled brands might not fully follow halal rules, but since they have certification and are Muslim-owned, the responsibility lies with them. I’m not just going to say bismillah and trust blindly, so I ask for guidance based on actual Quran and Hadith. Please make dua for me, and I will also pray to avoid doubtful foods. I’ve thought about some solutions: not trusting any carts that sell bacon, hot dogs, sausage, or cheese; just choosing vegetarian options when eating out; or avoiding street food altogether. I know I can cook at home, but sometimes I really crave food from outside. I avoid places that sell halal and non-halal pizza and only go to halal pizza shops that use kosher cheese. Sometimes it feels like becoming vegetarian might be the safest choice since many halal businesses seem careless with the rules. Jazakum Allahu Khairan for any advice or duas.
