Abstract
An enclosure includes a hollow robe disposed at a first end thereof and extending outwardly there-from. A collapsible bulb is attached to a second end of the enclosure for drawing atmosphere into the enclosure through the hollow robe when the bulb is squeezed and released. The enclosure further includes a viewing aperture. An indicating strip is disposed in the enclosure such that the strip is in environmental communication with the interior of the enclosure and viewable through the viewing aperture from outside of the enclosure. The indicating strip is configured to change in appearance when gases indicating the presence of food contamination are absorbed by the strip.
