(a) Comparison between surface swabbing and tissue excision techniques for the recovery of aerobic count, Enterobacteriaceae, Enterococci, coliforms, and Staphylococcus aureus from the outer surfaces of shoulder of control beef carcasses (). Values represent of the log counts. Columns with different letters within the same microbial category differ significantly ().
