Key takeaway
What This Development Means
Taiwan TFDA has proposed expanding its animal-product pesticide residue method from 129 to 182 entries and adding milk and fat matrices. Laboratories should assess standards, equipment and matrix-specific validation during the consultation.
Does The Draft Change Taiwan's Pesticide Maximum Residue Limits?
No. It proposes an official analytical method for detecting residues in animal products. Applicable maximum residue limits come from separate legal requirements. A broader method may improve enforcement capability, but it does not itself create or amend a residue limit.
When Is The Deadline For Comments On Notice 1151901007?
TFDA states 60 days from the day after Gazette publication rather than a calendar date on the notice page. Commenters should verify the Gazette date and counting convention and submit early enough to avoid relying on an inferred deadline.
Source basis: Taiwan Food and Drug Administration, notice 1151901007 on the draft animal-product pesticide residue method (12 August 2026)
The Taiwan Food and Drug Administration has proposed a 182-entry animal-product pesticide residue method, publishing notice 1151901007 on 12 August 2026 under Article 38 of the Act Governing Food Safety and Sanitation. The current muscle, offal and egg scope would extend to milk and fat, with implementation proposed for 1 July 2027 after finalisation.
What Taiwan's Animal-Product Pesticide Residue Method Changes
The draft would rename and broaden the current multi-residue method for pesticides in livestock and poultry products. Its method table expands from 129 to 182 pesticide entries, while matrix coverage adds milk and fat alongside the animal products addressed by the existing method. Some entries include metabolites or components, so the figure should not be presented as 182 unique active substances.
The technical attachment revises sample preparation, calibration and liquid- and gas-chromatography tandem mass-spectrometry parameters. Laboratories should use the official comparison document rather than treating the change as a simple 53-entry extension, because matrix effects, extraction recovery and instrument transitions may also change.
The notice is a draft method, not a new maximum residue limit and not a product prohibition. Existing legal residue limits and the current official method remain in place unless and until TFDA issues the final revision.
Which Businesses And Laboratories Are Affected
Official and contract laboratories are directly affected because the method may change standards inventories, instrument scheduling, validation plans and reporting templates. Food manufacturers, importers and exporters should also examine whether their testing specifications and certificates of analysis will align with the expanded scope.
The practical impact can extend through meat, poultry, dairy and egg supply chains to pesticide registrants, farms, retailers, proficiency-testing providers and reference-material suppliers. Businesses exporting to Taiwan may need laboratories capable of the revised matrix-specific method once it is final.
Analysis: Adding milk and fat increases the importance of matrix-matched validation. A laboratory that can cover all 182 entries in one matrix may not yet have suitable recovery, uncertainty or calibration evidence for another, so procurement teams should ask for method-scope detail rather than a generic accreditation claim.
What Organisations Should Do During The Consultation
Download the draft and comparison table, map the 53 added entries to products and historical detections, and compare required standards with current stock. Laboratories should conduct a feasibility review covering extraction, cleanup, calibration range, instrument transitions, quality controls and matrix-specific validation.
Submit technically supported comments within 60 days from the day after the Gazette publication specified in the notice. TFDA has not stated a calendar deadline on the webpage, so organisations should confirm the Gazette date and official counting rule rather than publish an inferred date.
What Happens Before July 2027
TFDA plans to implement the revised method on 1 July 2027, but that date remains part of the proposal. The authority may amend the scope or technical parameters in response to comments before issuing a final method. Businesses should track the official page for a final notice or correction and continue to follow current food safety requirements.
