Test principle of Path-Chek^® Coliforms:

• Bacteria are recovered from the surface of food manufacturing or processing equipment using a pre-moistened swab, which is capable of neutralising commonly employed detergents and sanitisers.
• The sample swab is then transferred into an organism specific media (swabs have a conveniently located break point so that they can easily be broken off into the growth media).
• Path-Chek^® Coliforms are incubated at 35-37°C for 18-24 hours If the specific target bacteria are present on the sample swabs, bacterial growth will cause the colour of the media to change.
