Hot-boned beef (excised 90 min postmortem) was chilled either by mixing coarse ground beef with CO2 snow or by immersing ground beef club packs in a brine chiller (-2.degree.C). Hamburger patties were prepared from both hot and cold-boned club packer, coarse ground beef after 0, 7, 14, and 21 days of storage (0.degree.C). Microbiological quality of the hot-boned ground beef was either superior or equal to that of the control. Purge present in all the chub packs after 21 days of storage was 1.0%. Patties prepared from CO2 chilled ground beef were more tender than control patties. Patties prepared from brine-chilled ground beef had greater cooking losses than patties prepared from cold-boned ground beef.
