Notes:
Fifty-five ground beef samples were analyzed to determine the effects of freezing with dry ice (-70°C) for 2 days (TR2) followed by 4 and 11 days. (TR3, TR4) in a laboratory freezer (-20°C) on aerobic plate counts (APC, 35°C), coliform, Escherichia coli, coagulase positive Staphylococcus aureus, and Clostridium perfringens recoveries. C. perfringens recovery is significantly reduced at TR2 and successively reduced at TR3 and TR4. Coliform and E. coli recoveries are significantly reduced at TR3 and TR4. S. aureus recovery is significantly reduced at TR4. APC values are not significantly reduced by freezing treatments. Statistical analysis of duplicate sample data (35 samples) gave low experimental error, estimated standard error, and sample error values indicating that enumerative procedures used have acceptable precision.
