Use RAPID'E.coli O157:H7 Agar for the detection, isolation, and presumptive identification of E. coli O157:H7 in food products. Results should be confirmed by standard reference methods appropriate for the food type being tested. Confirmation using latex is also validated for colonies isolated from RAPID'E.coli O157:H7 agar.

Other atypical (sorbitol+) E. coli O157:H7 colonies are blue to turquoise blue
100% specificity demonstrated by testing 50 strains of E. coli O157:H7 and 35 other strains
Selectivity is increased by the addition of novobiocin and other selective agents such as potassium tellurite
