During the past few years health authorities have been giving increasing attention to the problem of food contamination by rodents. Legislation provides penalties for existence of contamination whether contamination occurred on premises or had previously been contaminated before receiving. Fortunately, there is a quick and easy visual method to detect rodent contamination and the presence of rodents by the use of black light.

The detection of rodent contamination by black light is based on the phenomenon of rodent urine showing blue-white to yellow-white fluorescence when viewed under black light. The fresher the stain the more blue will fluoresce. Urine stains on food bags, containers, floors, etc. while invisible in white light, retains their fluorescence and are readily discernible under black light. Furthermore, rodents urinate when in motion and their paths are visible under black light in characteristic “droplet” pattern or trails. Rodent hairs show a blue-white fluorescence.

This useful inspection instrument – the black light – provides a means of detecting contamination, detecting presence of rodents on premises and can provide a means of estimating increase or decrease in the rodent colony. In certain warehouses all incoming foodstuffs are routinely inspected for contamination. With the same black light the warehouses own inspectors make routine checks for presence of rodents and signs of contamination.

Sanitation requirements for all food handling concerns is of great importance from standpoint of determining presence of rodents and contamination on the premises and safeguard against receiving foodstuffs already contaminated. We can ship your black light promptly.

Rodents have oily hair that is UV reactive, leaving smudge marks where they travel. Their droppings and urine trails along with gnawing marks are all signs of rodent and other mammal activity.

Review entry points which are important when considering where to inspect for rodent or animal urine. Areas such as windows, pipe entry points, flanges, door thresholds, utility lines, rooftops and downspouts.

Many pets have a favorite spot or spots they like to frequent. Like beside master's bed where their body oils collect and can be seen easily with our black lights.
