Guidance, not legal advice
Withdrawal periods are set on each product's label and enforced through the meat-safety and abattoir system (e.g. SAMIC / SAMPA requirements). Always follow the specific product label and confirm current requirements with your vet or abattoir.
What a withdrawal period is
A withdrawal period is the minimum time that must pass between the last treatment and slaughter (for meat) or use (for milk), so residues drop to a safe level. It is printed on the product — a dewormer might be 14 days, a long-acting antibiotic several weeks.
What a treatment record should capture
| Field | Why it's needed |
|---|---|
| Date of treatment | Starts the withdrawal clock |
| Product / medicine | Determines the withdrawal period |
| Batch number | Traceability of the product used |
| Dosage | Proves correct, safe use |
| Animal or group treated | Which animals are affected |
| Withdrawal-end date | The earliest safe slaughter/sale date |
Record the withdrawal-end date, not just the treatment
The single most useful thing you can capture is the date the animal is clear. Write the treatment date plus the withdrawal end date, and you can tell at a glance whether an animal is safe to send. FarmBind calculates that end date for you automatically.
Why it protects you, not just the buyer
A condemned carcass is a direct loss, and repeated residue failures can damage your standing with buyers and abattoirs. A clean, complete treatment record is your evidence that every animal you sent was clear — and your own early-warning system so you never load one that isn't.
Common questions
- What is a withdrawal period?
- It is the minimum time that must pass between treating an animal with a medicine and slaughtering it for meat (or using its milk), so drug residues fall to a safe level. The period is set on each product's label and varies from days to several weeks.
- What must a treatment record contain?
- The treatment date, the product and its batch number, the dosage, the animal or group treated, and the withdrawal-end date — the earliest date that animal is safe to slaughter or sell. Recording the end date is what stops you accidentally sending an animal still within withdrawal.
