You don't necessarily need to clean the plant daily. Bigger ag producers (especially poultry) are protected from certain food-borne illness lawsuits because it is impossible to remove those pathogens from the food supply, even with cleaning. Salmonella is one of them and there is a new antibiotic resistance strain that is spreading.
I went looking for example videos of cleanup:
