Quality and hygiene are non-negotiable. To sell yam flour in bulk or internationally, one must meet:
-
Local food authority certifications (e.g., NAFDAC in Nigeria, FDA in Ghana)
-
International food safety standards (ISO, HACCP)
-
Labeling with nutrition facts, batch numbers, and expiry dates.
Training in Good Manufacturing Practices (GMP) and periodic inspection help maintain credibility with buyers and regulatory bodies.
