Assalamualikum Wa Rahmatullahi Wa Barkatahu,
Please confirm if we can trust the Halal certification provided by ISWA (Islamic Society of Washington Area) and IFANCA (Islamic Food and Nutrition Council of America).
ISWA's meat and livestock certification is reliable but their certification of poultry is not reliable because they do mechanical slaughter.
I do not have enough information at the moment to say anything about the meat or poultry certification of IFANCA.
And Allah knows best.
