The short version
- Aquaculture Health Plans must be approved, dated, and signed by a certified veterinarian or aquatic health professional.
- Health plans require annual updates, or cycle-based updates for shorter production cycles, and inclusion of approved treatments.
- Antibiotics and chemicals must never be used for growth promotion or prophylactic treatment across certified operations.
- Batch identification systems must prevent accidental harvesting of aquatic species during active preharvest withdrawal periods.
Regulatory context and health management rationale
Under GLOBALG.A.P. Integrated Farm Assurance version 6 for Aquaculture, health management and medicinal oversight form mandatory compliance foundations. Disease prevention, animal welfare protection, and food safety depend on structured veterinary oversight across all life stages, including hatcheries, grow-out units, and transport holding systems. Section AQ 20 defines the operational principles governing species health, treatment authorization, and withdrawal period tracking.
This regulatory framework directly affects farm managers, compliance leads, certified veterinarians, and internal auditors. The standard enforces a preventive approach to aquatic animal health, prioritizing biosecurity, vaccination, and optimal rearing conditions over therapeutic chemical intervention. Where therapeutic treatments become necessary, management must demonstrate that chemical applications follow legal prescriptions and strict residue containment rules.
Failing to maintain a valid health plan or releasing aquatic stock before completing mandatory preharvest withdrawal periods creates severe food safety risks. Certification bodies evaluate treatment logs, residue testing records, and veterinarian authorizations during annual audits. Non-compliance with veterinary oversight criteria leads to Major Must failures and potential certificate suspension.
Core components of an approved Aquaculture Health Plan
Principle AQ 20.02.01 mandates that every certified farm site maintain a documented Aquaculture Health Plan approved by a certified veterinarian or aquatic animal health professional. The approving professional must hold legal authority in the production jurisdiction to diagnose diseases and prescribe veterinary medicines. The document must contain the professional's full name, organizational affiliation, signature, and approval date.
The Aquaculture Health Plan requires systematic updates to maintain audit compliance:
- Update frequency: Principle AQ 20.02.01 requires updating the plan annually, per production cycle for short-cycle species, or whenever new medicines or treatments are introduced.
- Disease and vaccination protocols: Section AQ 20.02.01 requires listing potential regional diseases, preventive measures, biosecurity controls, quarantine procedures, and vaccination protocols.
- Approved treatment inventory: The plan must detail all permitted medicines, active substances, indications, dosage rates, application methods, and preharvest withdrawal periods.
- Banned compound prohibition: Section AQ 20.02.01 explicitly prohibits Codex Alimentarius banned substances, including nitrofurans, malachite green, chloramphenicol, and stilbenes.
- AMR and sensitivity monitoring: Section AQ 20.02.01 requires monitoring antimicrobial resistance trends and rotating active substances to prevent pathogen resistance.
Treatment authorization, batch identification, and withdrawal rules
Principle AQ 20.03.02 and Principle AQ 20.03.04 dictate that all vaccines, medicines, and chemical treatments must be authorized by a certified veterinarian and restricted to legally permitted active substances. Antibiotics must be applied exclusively as therapeutic treatments following diagnosis of an infectious bacterial disease. Prophylactic antibiotic administration and growth promotion applications are strictly prohibited under Principle AQ 20.03.06 and Principle AQ 20.03.08.
When therapeutic treatments are administered, strict batch identification and withdrawal tracking protocols must be executed:
- Preharvest withdrawal identification: Principle AQ 20.04.03 requires a physical and digital system identifying treated production units to prevent accidental harvest during withdrawal windows.
- Administration record details: Principle AQ 20.04.01 mandates recording batch numbers, treatment dates, treated biomass, dosage, administration method, withdrawal completion date, and earliest safe harvest date.
- Flushed feed withdrawal start: Principle AQ 20.02.01 specifies that the preharvest withdrawal period begins when medicated feed is fully flushed from the farm feeding system.
- On-farm mixing controls: Principle AQ 20.03.05 requires avoiding on-farm feed mixing with medicines unless justified, prescribed, and executed by trained staff with active ingredient verification.
- Residue testing verification: Principle AQ 21.01 mandates tissue residue testing by ISO 17025 accredited laboratories to verify maximum residue limit compliance prior to market dispatch.
Comparison of treatment oversight and record requirements
| Compliance parameter | Standard requirement | Mandatory audit evidence | Non-conformance risk |
|---|---|---|---|
| Health plan approval | Approved, signed, and dated by certified veterinarian | Written Aquaculture Health Plan with veterinarian credentials | Major Must failure if unapproved or expired |
| Treatment records | Log purchase details, dosage, biomass, administrator, and dates | Comprehensive administration logs and veterinary prescriptions | Immediate non-conformance for missing treatment entries |
| Withdrawal tracking | Maintain batch isolation system preventing accidental harvest | Physical unit labeling and verified withdrawal calculation records | Critical food safety risk and immediate product suspension |
| Chemical prohibitions | Total ban on growth promoters, prophylactic antibiotics, and Codex banned chemicals | Purchase invoices, inventory logs, and tissue residue test reports | Immediate certificate cancellation for illegal chemical use |
What to do now
- Audit Aquaculture Health Plan validity: Review your written health plan to confirm that annual updates, veterinarian signatures, and approved treatment lists are current.
- Inspect treatment administration logs: Verify that purchase records, administration dates, dosage calculations, and calculated withdrawal dates are logged for every treated batch.
- Test withdrawal batch isolation: Check physical signage and IT inventory locks on treated ponds or net pens to ensure accidental harvesting is impossible during withdrawal windows.
- Review laboratory residue reports: Confirm that tissue residue testing for listed substances is performed by an accredited laboratory prior to harvesting.
