McDonald's was using fresh beef in some areas (e.g. California's Central Valley locations like Stockton) clear back to 1978 at the latest. It becomes a logistics issue and expense, plus the environmental impact of additional delivery trips. “These burgers are hotter and juicier than our previous quarter-pound patties, ...” Well, sure, but that's only at the time you pull them from the grill. When you then just stuff the cooked patties into a heat tray for (perhaps hours) later assembly into a sandwich (modern McD procedure, unlike the old days), the benefit is mostly lost.
