21 CFR 589 BSE Feed Ban: the Operating Manual
The FDA BSE-prevention rules at 21 CFR 589.2000 (ruminant feed ban) and 589.2001 (cattle materials prohibited in animal feed, CMPAF) are the foundation of US bovine spongiform encephalopathy control in animal food. Any plant handling rendered protein, animal-sourced ingredients or shared lines with ruminant feed lives under these rules. Inspections by FDA CVM and state feed officials focus on segregation, labelling ('Do not feed to cattle or other ruminants'), and records demonstrating BSE-prohibited materials never enter ruminant feed. This guide is the operating manual.

Two rules — 589.2000 and 589.2001
21 CFR 589.2000 (1997 ruminant feed ban) prohibits mammalian protein in ruminant feed with limited exceptions (blood/blood products, milk, gelatin, inspected meat scraps from non-ruminants under specific conditions). 21 CFR 589.2001 (2008 cattle materials prohibited in animal feed, CMPAF) goes further: it prohibits high-risk cattle materials — the brain and spinal cord of cattle 30 months and older, and the entire carcass of cattle not inspected and passed for human consumption unless brain/spinal cord are removed — from ALL animal feed, not just ruminant feed. The two rules layer.
Segregation — the operational core
Any plant handling both prohibited and non-prohibited materials must segregate by dedicated equipment, sequencing with documented flush/cleanout, or physical separation. Shared equipment requires validated cleanout sequences with sampling evidence. Records of cleanout, sequencing decisions and segregation breaches are FDA inspection focal points. Most rendering plants and feed mills run dedicated ruminant vs non-ruminant lines because the cleanout discipline at scale is unforgiving.
Labelling — 'Do not feed to cattle or other ruminants'
Feed and feed ingredients containing prohibited material under 589.2000 must carry the cautionary statement 'Do not feed to cattle or other ruminants' on the label and on every invoice and shipping document. The statement applies even to ingredients sold to manufacturers — the label discipline persists through the supply chain. Pet food using rendered protein typically carries the cautionary statement on bulk-shipment paperwork; the consumer-facing retail label is governed separately by AAFCO.
Records — what FDA inspects
Renderers and feed mills must keep records sufficient to demonstrate compliance: receipt of incoming animal materials with classification, processing batch records with segregation evidence, cleanout records for shared equipment, outbound shipping documents with the 'Do not feed' statement, and supplier statements certifying compliance with 589.2001 (no high-risk cattle materials). Records are retained for the period specified in the regulation and produced on inspection. Missing or weak records are the most common 589 finding on FDA Form 483.
Pet food and BSE — why this matters even if you don't make ruminant feed
Pet food is animal feed under FDA's framework, so 589.2001's prohibition on high-risk cattle materials applies directly. A pet-food plant using rendered protein must qualify the renderer's compliance with 589.2001 — typically through a written supplier statement plus periodic audit. Pet-food plants sharing a campus with ruminant-feed production must also demonstrate physical separation. Many premium pet-food brands have removed all 589-restricted materials from their formulas to simplify the segregation and labelling burden.
A 90-day 21 CFR 589 readiness path
Days 1–15: ingredient inventory classified against 589.2000 and 589.2001. Days 16–30: equipment map and segregation strategy — dedicated vs sequenced vs shared with cleanout. Days 31–50: supplier qualification refresh — renderer statements, audit cadence, COA. Days 51–70: label and shipping-document audit for the cautionary statement. Days 71–85: records review and mock 589 inspection. Days 86–90: management review and CAPA closure.

Frequently asked
Does 589 apply to my pet-food plant if I never make ruminant feed?
589.2001 (CMPAF) applies because it covers all animal feed, including pet food. 589.2000 (ruminant feed ban) is structurally less relevant if you never make ruminant feed, but it still applies to your incoming rendered-protein ingredients — your supplier had to comply, and you carry the cautionary statement on any product containing 589-restricted materials. You can't ignore 589 even if you only make pet food.
What counts as 'high-risk cattle material' under 589.2001?
Brain and spinal cord from cattle 30 months of age or older, and the entire carcass of cattle not inspected and passed for human consumption unless brain and spinal cord are removed (along with a few specific tissues). The renderer is responsible for removing or excluding these materials before producing protein that enters animal feed. Pet-food plants receive renderer statements certifying CMPAF compliance.
Is a supplier statement enough, or do I need to audit renderers?
Under FSMA Part 507 Subpart E, a supplier statement is a starting point, not an endpoint. The risk profile of rendered protein (BSE consequence, history of regulatory findings) typically pushes verification to onsite audit or a recognised third-party audit, plus periodic COA review. Most pet-food plants run an annual or biennial renderer audit specifically against 589 compliance.
What does FDA look for during a 589 inspection?
Ingredient classification records, segregation strategy and execution evidence, cleanout records for shared equipment, the cautionary statement on labels and shipping documents, supplier qualification records, and traceability from incoming animal material through finished product. The two most common findings: missing or inconsistent cautionary statements, and inadequate records for shared-equipment cleanout.
