Questions

How many custom-exempt plants does Massachusetts have?

3 establishments in Massachusetts carry the flag in the FSIS directory of 2026-09-01, in 3 counties. Each is listed with its establishment number so you can verify it at FSIS.

What does the custom-exempt flag mean?

Establishments that report custom-exempt slaughter or processing to FSIS under 9 CFR 303.1. A custom-exempt plant can process an animal the customer already owns, a whole, half or share bought before slaughter, and returns it in packages marked Not for Sale. This is the list behind every half-cow purchase.

Are state-inspected plants included?

No. This list is federal grants of inspection only. Massachusetts has no state meat inspection program, so federal inspection and the custom exemption are the two routes available.
