Halloween is a special day at NSF International as NSF’s staff of more than 500 microbiologists, engineers, chemists, toxicologists, public/environmental health professionals trade in their lab coats and business attire for fun, themed costumes.

Cubicles, offices, conference rooms, and the warehouse are transformed into unique Halloween scenes for the day. Even senior management participates, dressing up, judging and handing out treats to colleagues who visit their team’s displays.

Some of last year's winning departments included the toxicology team’s Pirates vs. Ninjas, the accounting department’s apple orchard, and HR’s Mexican fiesta.

Some of this year's winning teams included the IT deparment's NSF TV series, the Toxicology department's monster ball and Marketing’s Disco Studio 789.
