# Auditing a new co-packer: what do you check before the first order?

We are onboarding a new co-packer and want to avoid the classic surprises. Interested in how others run the first audit.

- Do you audit the site yourself or rely on their GFSI certificate?
- Which records do you sample first — HACCP plans, batch sheets, or sanitation logs?
- How do you test allergen and changeover controls in practice?

Share the one check that has saved you the most trouble downstream.
