Feed and Cereals Analysis in Thailand — Why Feed Is the Foundation of Food Safety
Feed and cereals analysis in Thailand, supported by Randox ELISA kits and Biochip Array solutions available through BCST, addresses the most upstream point in the food safety chain. Specifically, it targets the quality of the raw materials that enter animal production systems. Every residue detected in meat, poultry, dairy, and aquaculture products traces back, at least in part, to what the animal consumed.
Thailand’s feed industry supplies one of the most productive livestock and aquaculture sectors in Asia. Feed mills process maize, soybean meal, cassava, and other raw materials from multiple countries. Each origin carries different contamination risks depending on harvest conditions and storage history. Without systematic screening at goods receipt and during processing, contamination passes invisibly through the feed chain. Consequently, it accumulates in animal tissue and surfaces only at the border of an export market — by which point the damage is done.
Randox feed and cereals products give Thai feed mills, livestock operations, and grain processors validated, documented screening capability. Moreover, the documentation these tools produce supports HACCP records, ISO 22000 quality systems, and export compliance files. BCST distributes the complete current Randox feed and cereals range in Thailand, providing IFU-level technical support and full documentation for every kit and array.
The Regulatory Framework for Feed Safety
Thai feed producers supplying livestock operations with EU export obligations must comply with Commission Regulation (EU) 2023/915. This regulation establishes EU maximum levels for contaminants and undesirable substances in feed. In practice, growth promoters including ractopamine and beta-agonists are prohibited in the EU and in over 160 other markets. Detection of these substances in feed supplied to animals destined for export constitutes a violation at the source — before the animal has been slaughtered.
Codex Alimentarius standards for feed contaminants additionally apply to international trade disputes. Compliance with these frameworks requires systematic, documented screening. Randox ELISA kits and Biochip Array solutions provide the validated tools to produce that documentation.
Platform 1 — ELISA Kits for Feed and Cereals Analysis
Who Should Choose ELISA
ELISA suits operations beginning systematic feed safety screening, feed mills testing moderate batch volumes for specific analytes, and any operation where capital instrument investment in the Evidence Investigator is not yet justified by testing volume. Any professional laboratory can implement Randox ELISA kits with a microplate reader at 450 nm, an incubator, and a pipetting station — no additional capital expenditure required.

Why this kit is uniquely significant: Ergot alkaloids are neurotoxic fungal metabolites produced by Claviceps purpurea infecting cereal crops. In livestock, ergotism causes vasoconstriction progressing to vaso-occlusion and gangrenous changes, abortions, feed refusal, dizziness, and convulsions. Commission Regulation (EU) 2023/915 establishes maximum levels for the sum of six ergot alkaloids and their epimers in feed. Randox RDX-EA3491 is the only commercially available ELISA kit validated against this requirement. For Thai feed mills sourcing European-origin cereals or supplying livestock operations with EU export obligations, no other commercially available ELISA kit currently fills this compliance gap.
Note on RDX-EA10408: The RDX-EA10408 Accessory Kit provides two additional sets of six standards (6×1 mL each) for high-volume operations that exhaust the standards included in the EA3491 kit. It is optional — the EA3491 kit contains one set of six standards sufficient for normal operation. Contact BCST for EA10408 pricing if your testing volume requires additional standards.
Platform 2 — Biochip Array Kits for Feed and Cereals Analysis
Who Should Choose Biochip Array
Biochip Array Technology suits high-volume operations testing multiple mycotoxin classes simultaneously where the cost savings from consolidated multi-analyte testing justify the Evidence Investigator instrument investment. The key advantage is fundamental — one prepared sample yields simultaneous results for multiple mycotoxins in a single run. This replaces separate ELISA assays per analyte class and the associated reagent, labor, and time costs.

Applications in Thailand
Feed Mills at Goods Receipt
Feed mills testing incoming maize, soybean, and other raw materials use Randox ELISA kits to screen for aflatoxins, growth promoters, and ergot alkaloids before ingredients enter the production line. Additionally, the Myco 7 Biochip Array screens for seven mycotoxins simultaneously — eliminating the need to run separate assays per mycotoxin class and dramatically reducing the time and cost of comprehensive incoming material screening.
Livestock Operations with EU Export Requirements
Integrated livestock operations supplying EU export markets verify that feed given to their animals is free from banned growth promoters before incorporation. Specifically, RDX-SU2148 and RDX-RT3451 enable urine and feed screening for beta-agonists and ractopamine — the most commercially significant banned growth promoters for Thai livestock exporters.
Government Feed Monitoring Programs
The Department of Livestock Development and other Thai government agencies conducting national feed monitoring programs use Randox ELISA kits and Biochip Arrays for validated, documented surveillance. The AOAC-certified Myco 7 array and ISO 9001-certified ELISA kits provide the validation credentials that government monitoring programs require.
Meat and seafood residue screening details are available on the Meat and Seafood Analysis Thailand page. The complete Randox portfolio overview is at the Randox Food Diagnostics Thailand hub page. Additionally, technical background on the ELISA principle is available on the ELISA Technology page.
Frequently Asked Questions
Q: Does the Ergot Alkaloids ELISA require a separate accessory kit?
The RDX-EA3491 kit includes one set of six standards sufficient for normal operation. The optional RDX-EA10408 provides two additional sets for high-volume operations. The Extraction Solution — 60% methanol, 40% double deionised water, 0.4% concentrated formic acid — must be prepared on-site using standard laboratory reagents not supplied with the kit. Contact BCST for full preparation guidance and RDX-EA10408 pricing.
Q: Can I use the Beta-Agonist ELISA for tissue testing?
The Immunoaffinity Column Kit previously required for liver, kidney, and muscle tissue analysis with RDX-SU2148 has been discontinued. Randox is evaluating an alternative. Urine, feed, milk, and serum analysis are fully operational. For growth promoter tissue screening now, the Evidence Investigator with Growth Promoters Immunoaffinity Columns is the current available route. Contact BCST for the latest update.
