Birko’s Beefxide® and Porkxide™ Efficacy Validated By Independent Study at Angelo State University

Birko's antimicrobial interventions for beef and pork demonstrated effective

Online PR News – 22-June-2012 – Henderson, Colo. – Birko, a leader in providing food safety solutions to the protein processing, food and beverage industries, today announced that the efficacy of its antimicrobial interventions for beef and pork, Beefxide® and Porkxide™, has been validated by independent testing at Angelo State University, San Angelo, Texas.

In testing conducted during February and March 2012, beef and pork carcasses were treated with either Beefxide® or Porkxide™, or lactic acid. The data showed that Beefxide® and Porkxide™ were effective as antimicrobial interventions for reducing microbial numbers on intact beef and pork carcasses, respectively.

“These results match those that we have obtained in other studies, further indicating that Beefxide® and Porkxide™ will be valuable antimicrobial aids for processors,” said Elis Owens, Ph.D., chemist/microbiologist for Birko.

Angelo State University recommended further testing to statistically confirm the treatment effect of the products.

Beefxide® received approval in May 2011 from the USDA-FSIS for use as an antimicrobial processing aid on beef carcasses, primals, cuts and trim, and is listed in FSIS Directive 7120.1. Birko received simultaneous approval for its Porkxide™ intervention for use as antimicrobial processing aids on pork products.
