A taqueria serves each table an open bowl of house salsa with chips. At closing, several bowls come back nearly full. A cook suggests pouring them back into the batch container for tomorrow. What is the correct decision?

Open bowls at guest tables are exposed to double-dipped chips, saliva, and hands, and none of that can be undone by straining, chilling, or freezing. A sieve removes particles but not pathogens, staying below 41°F limits growth but does not remove contamination, and freezing holds pathogens rather than killing them. Returned open food must be thrown out, and pouring it into the master batch would contaminate the entire container.
