A food handler who is throwing out garbage in an outdoor dumpster must securely tie or secure the garbage bag before throwing it in. After disposing of the garbage, the dumpster lid should be closed to prevent pests and maintain sanitation. It is also important to ensure that the garbage bag falls below the rim of the dumpster and to keep the dumpster area clean to avoid contamination and pest infestation. Proper hand hygiene after garbage disposal is essential as well.
