Wis. Admin. Code § ATCP 88.18
(1) Temperature before packing. Eggs that are held by an egg handler before packing for more than 36 hours after they are laid shall be kept at an ambient temperature of 45° Fahrenheit (7° Celsius) or less. Eggs that have been refrigerated may be held at room temperature, for up to 36 hours immediately before washing, to decrease the risk of thermal checks caused by washing cold eggs with warm water.
Note: It is recommended that eggs be processed and packed as soon as practicable and within 5 days after they are laid.
(3) Temperature during transport. During transport to a retail food establishment and upon receipt at a retail food establishment eggs shall be held at an ambient air temperature of 45° Fahrenheit (7° Celsius) or less.
Note: Mechanical refrigeration is recommended for eggs that are in transport for more than 4 hours.
