Claim:
1. An apparatus for monitoring hygiene, comprising: a dispensing device positioned outside an area requiring sanitary conditions for dispensing a sanitizer; a first sensor associated with the dispensing device, said first sensor being activated when sanitizer has been dispensed; a second sensor disposed to view a portal to the area requiring sanitary conditions for detecting when an individual has passed through the portal, said second sensor viewing a side of the portal proximal the dispensing device; a third sensor disposed to view the portal to the area requiring sanitary conditions for detecting when an individual has passed through the portal, said third sensor viewing a side of the portal distal the dispensing device; and a programmed controller connected with said first sensor, the second sensor, and third sensor; the controller having programming logic that compares the activation times of said first, second and third sensors and activates a perceptible able-to-pass signal for a pre-determined period of time after activation of the first sensor, and in the absence of the able-to-pass signal without a time delay produces an alert signal and an unsafe passage signal in case the second sensor is activated before the third sensor, or in case the third sensor is activated before the second sensor, produces an alert signal and an unsafe passage signal after a time delay during which the first sensor has not been activated.
