解析

Shell eggs must be received and stored in refrigerated equipment that maintains an ambient air temperature of 45°F or below, which helps limit Salmonella growth inside the egg. An ambient 55°F or 50°F is too warm to meet that rule. A cooler running at 41°F would also satisfy it, but the question asks what the Code requires, and the Code's shell-egg allowance is an ambient 45°F — so naming 41°F as the only acceptable figure states the rule incorrectly. Eggs should be used promptly after receiving.
