Abstract: An example system includes a light intensity measuring apparatus couplable to a food processing apparatus and a computing system. The light intensity measuring apparatus includes a chamber configured to receive a water sample from the food processing apparatus, a light source, a detector configured to detect light that has passed through the water sample and measure multiple times intensities of wavelengths of the light to obtain multiple sets of measured intensities of wavelengths, and a communication module configured to provide the multiple sets of measured intensities of wavelengths. The computing system may receive the multiple sets of measured intensities, process the multiple sets to obtain a set of values, apply a first set of decision trees to the set of values to obtain a first result indicating a positive or negative foodborne pathogen detection, generate a notification indicating either the positive of negative detection, and provide the notification.

Abstract: An example method includes receiving multiple spectrometer scans of a sample obtained from a person. A spectrometer scan includes intensities of wavelengths of light in a range of wavelengths. The light has passed through at least a portion of the sample. For multiple wavelengths of light in the range of wavelengths, a particular profile intensity utilizing particular intensities of wavelengths of light included in the multiple spectrometer scans is calculated to obtain multiple profile intensities. Slopes of the multiple profile intensities at multiple wavelengths are calculated to obtain a set of slopes. A fitting function is applied to the set of slopes to obtain a set of values. A set of decision trees is applied to the set of values to obtain a result. The result indicates either a positive pathogen detection or a negative pathogen detection for the sample. A pathogen detection notification is generated indicating either the positive pathogen detection or the negative pathogen detection for the sample. The pathogen detection notification is provided.
