Between January 1 and Feburary 28, 2003 150 fresh and frozen ground beef samples were purchased from retail establishments in Ohio, Florida and Washington D.C. Seventy three of the samples were labeled with words to the effect that the cattle from which the beef was derived had not received any antimicrobial agents. The remaining samples had no such label claim.
All samples were frozen for a period of time not exceeding 2 weeks prior to microbiological analysis. One hundred microliters of each frozen BPW enrichment was spread plated on enterococcosel agar (Becton Dickinson) supplemented with 32 mg/ml of vancomycin.
