Tooling around

This actually looks promising. Space age tools may help reveal fecal matter on produce, the USDA ARS reported recently. Portable inspection devices that detect food safety and quality problems are being developed by USDA ARS scientists.

Prototypes include binoculars with lenses that detect fecal matter on meat, produce or processing equipment—as well as diseases or quality defects. A camera/light combination can be helmet-mounted or used in a hand-held device to expose fecal matter as white specks on an eye wear-mounted computer display.
