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. This product includes 100 g of dehydrated medium. Supplements of novobiocin (10 mg/L) and potassium tellurite (0.8 mg/L) must be added to this medium. Features and Benefits Detection on a single plate Typical (sorbitol-/β-glucuronidase-) and atypical (β-glucuronidase+) E. coli O157:H7 colonies are dark blue or black Other atypical (sorbitol+) E. coli O157:H7 colonies are blue to turquoise blue 99% 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 Results with RAPID'E.coli O157:H2 Medium in ≤48 hr Validations Certified NF VALIDATION according to the ISO 16140 standard and validated by the AOAC.
