- 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.
nBPW for Poultry Carcasses and Parts

On July 1st, 2016, the USDA Agricultural Research Service (ARS) released a newly developed Neutralizing Buffered Peptone Water ( nBPW ).


- This solution came from a study by the ARS (initiated by the FSIS) to determine whether antimicrobial sanitizers might interfere with testing for Salmonella.
- ARS researchers found that sanitizers used on poultry carcasses to reduce pathogens might cause false-negative results in tests for Salmonella.

- FSIS believes the new nBPW solution will eliminate any problem of antimicrobial carryover in Salmonella tests.
