Withholding periods (WHP) and Export Slaughter Intervals (ESI) are critical compliance requirements for Australian livestock producers. Getting them wrong can result in residue failures and market exclusion.
What is a Withholding Period?
A WHP is the minimum period that must elapse between the last treatment of an animal with a chemical product and the time it can be slaughtered for human consumption.
What is an ESI?
The Export Slaughter Interval (ESI) is a separate requirement for animals destined for export markets. ESIs must be observed to maintain access to export markets.
Key Rules to Follow
- Always read the label before treatment — the label is the law
- Record treatment dates, product used, batch numbers, and animal IDs in your chemical records
- Observe both the WHP and ESI — whichever is longer applies for export animals
- Calculate from the date of the last treatment, not the first
- Different withholding periods may apply for meat and milk on the same product
Always Check the Current Label
WHPs and ESIs vary by product, formulation, and intended use — and they can change when labels are updated. Never rely on remembered figures or third-party sources. Always check the current registered label before treatment. TGRM can provide the current label or SDS for any product we stock — just ask.
