Highly sensitive detection of pathogens is effective for screening meat during quarantine inspection and export. The "micro-amount of virion enrichment technique" (MiVET) was recently developed, which is a new method combining virus concentration with immunomagnetic beads and simple RNA extraction with sodium dodecyl benzenesulfonate (SDBS) for the specific and sensitive detection of avian influenza viruses (AIVs). AIV subtypes H3N2 and H4N2 were used to spike the surface of chicken breast meat samples.

A fluorescent loop-mediated isothermal amplification (fLAMP) assay targeting BLV env sequences was developed and used to evaluate 100 bovine blood samples. Compared with a conventional real-time PCR (rPCR) assay, the fLAMP assay achieved 87.

While it is important to identify the sources and propagation routes of the spread, such strategies are often hindered by incomplete epidemiological evidence. Isolation/detection of micro-amounts of pathogens from environmental samples is rarely successful due to the very low contamination level.
