Differentiate at a glance with HardyCHROM™

HardyCHROM™ is Hardy Diagnostics’ line of chromogenic, selective and differential culture media, recommended for use in primary cultivation and isolation of microorganisms. Hardy Diagnostics was the first to introduce chromogenic culture media to the United States. See why we have been a leader in chromogenic media ever since!

  • HardyCHROM™ Listeria – selective isolation of Listeria monocytogenes from food and environmental samples.
  • HardyCHROM™ ECC – rapid and reliable detection and differentiation of E. coli and other coliforms.
  • HardyCHROM™ Staphylococcus aureus – allows for the rapid and reliable detection of S. aureus from both clinical and food specimens within 24 hours.
  • HardyCHROM™ sakazakii – for the isolation and chromogenic detection of Cronobacter sakazakii.
  • HardyCHROM™ Salmonella – a differential medium that facilitates the isolation and differentiation of Salmonella spp. from other members of the family Enterobacteriaceae.
  • HardyCHROM™ Vibrio – a selective and differential screening media recommended for the isolation of pathogenic Vibrio spp. from food and environmental sources.
  • HardyCHROM™ O157 – a selective and differential medium recommended for the isolation of enterohemorrhagic E. coli O157 from food and environmental sources.
  • NEW! HardyCHROM™ Campy – for the selective cultivation and differential isolation of Campylobacter species from food and poultry samples based on colony color.

Improve the efficacy of your poultry testing by using Hardy’s nBPW solutions!

nBPW is recommended for use as a rinse (or swab) for poultry carcasses and parts. USDA Institutes this “Fix” due to Salmonella false negatives. The new buffer is officially replacing currently used Buffered Peptone Water because of it’s increased effectiveness in reducing the effect of potential carryover of antimicrobials. Read the FSIS Notice release on June 8th, 2016.
