Reducing microbial growth on food preparation, storage, or processing apparatus

A method comprising:

• disposing a lighting array including one or more antimicrobial lighting segments, each antimicrobial lighting segment including one or more elements, wherein each element of the one or more elements emits light at a wavelength and irradiance sufficient to inactivate one or more microorganisms on at least one target surface associated with a food machine;
• receiving, by one or more processors, usage information indicative of a number of food machine cycles completed by the food machine in a specified period of time;
• determining the food machine is in one of a first, high usage state or a second, reduced usage state based on the number of food machine cycles completed by the food machine in the specified period of time;
• and
• individually controlling each of the one or more antimicrobial lighting segments based on determining the food machine is in one of the first, high usage state or the second, reduced usage state.

A non-transitory computer-readable storage medium comprising instructions that when executed by one or more processors cause the one or more processors to:

• receive usage information indicative of a number of food machine cycles completed by a food machine in a specified period of time;
• determine the food machine is in one of a first, high usage state or a second, reduced usage state based on the number of food machine cycles completed by the food machine in the specified period of time;
• and
• individually control each antimicrobial lighting segment of a lighting array comprised of a plurality of antimicrobial lighting segments to emit light at a wavelength and irradiance sufficient to inactivate one or more microorganisms on at least one target surface associated with the food machine based on determining the food machine is in one of the first, high usage state or the second, reduced usage state.
