The tank of a vehicle used to transport dairy products and its equipment must be washed and sanitized after the day’s last complete unloading at the dairy plant or, if the milk cannot be unloaded from the tank on the day it is collected, after the first complete unloading at the dairy plant on the following day. The truck tank and equipment must also be washed and sanitized after unloading the other food products referred to in section 11.4.6.
