While it doesn't call out recently prepared food, the CDC disagrees:
> Coronaviruses are generally thought to be spread from person-to-person through respiratory droplets. Currently there is no evidence to support transmission of COVID-19 associated with food. Before preparing or eating food, it is important to always wash your hands with soap and water for 20 seconds for general food safety.
