ELISA negative qPCR detected results are common in food laboratories due to differences in target detection, sensitivity, and matrix effects. Understanding whether DNA persistence, protein degradation, or analytical sensitivity is responsible is critical for structured and audit-defensible decision-making.

Zoning in food factories is critical to preventing cross-contamination and strengthening HACCP and GMP systems. This practical guide explains how to define low, medium, and high risk areas on the factory floor and control movement effectively.

Allergen management goes beyond labels and supplier declarations. This post explains how qPCR for allergen verification supports cleaning validation, cross-contact assessment, and evidence-based allergen control in food manufacturing.

A “Detected” result in qPCR often triggers immediate concern, but detection does not always equal contamination. This post explains what qPCR positives truly mean across microbial, GMO, and allergen testing — and how correct interpretation prevents unnecessary panic and wrong quality decisions.
