Abstract
A non-chemical, non-residue method of controlling pests, pathogens and other undesirable organisms found in food supplies. The organisms are exposed to ultra-short pulses of ultraviolet light emitted at a wavelength which is absorbed by surface coloring chemicals in the insect, such as entegumen. The coloring chemicals act as a heat sink to the ultraviolet photons, and the undesired organisms are selectively heated without harming adjacent food objects. The heat thus induced in the insects causes irreparable or irreversible lethal damage.
