We provide rapid testing products and integrated solutions for microbiological testing, hygiene monitoring, pesticide and veterinary drug residues, chemical screening, biotoxins, grain and feed safety, dairy and water testing, and edible oil quality control. Selected products have been evaluated or certified through recognized international programs.
Supported by established manufacturing, quality-management and supply-chain systems, FSTest delivers consistent quality, flexible customization and dependable international supply. Through continuous innovation, regional adaptation and professional technical support, we help global partners implement faster, simpler and more reliable food safety testing across diverse markets and applications.
For ready-to-eat (RTE) food operations, environmental monitoring is more than a testing activity. It is a verification system used to assess sanitation controls, identify potential harborage sites and support timely corrective action before contamination reaches product. Because Listeria may be present at low or uneven levels, reliable detection begins with the monitoring plan—not with the test kit alone.
Colony counting is often treated as a simple final step in food microbiology. In practice, colony morphology, plate density, spreading growth, background artifacts, image quality and analyst interpretation can all affect the reported colony-forming unit (CFU) result. Automation can make visual enumeration more consistent, but it does not replace control of the microbiological method.
Following EU 2026 ARA oil limits, this 4-tier workflow screens Bacillus cereus for infant formula. It uses rapid plate counting and ISO 18465 LC-MS/MS to detect heat-stable cereulide across raw materials, production and finished goods.
To be published in August 2026, this industry-academia textbook covers mainstream food rapid testing technologies, national standards and smart supervision with QR teaching videos. It serves food students and testers to improve global food safety control.
Constantly, we are advancing our state of technology and extending branches of new products and services, all of which are guided by our values to provide for the ever-evolving needs of our clients.
