I go on any trouble

There is absolutely no harm or danger in scanning a rotisserie chicken or exposing it to an LED light. This concern stems entirely from a viral internet joke. The rumor started because of a viral video featuring a Costco shopper named Dave, who went to the checkout lane wearing a custom T-shirt printed with the barcode for a Costco rotisserie chicken. He insisted that the cashier scan his chest instead of the chicken, claiming he didn't want the checkout scanner's LED lights to "poison" or "contaminate" his food. SafeGrocery store scanners use completely harmless, low-power LED lights or weak visible lasers to read barcodes. 1. No Radiation: These lights do not emit ionizing radiation (like X-rays or gamma rays). They cannot alter the molecular structure of your food, leave behind any residue, or make the food toxic. 2. Everyday Exposure: The light from a grocery scanner is no different than the light hitting the chicken from the store’s overhead light bulbs, your kitchen lights, or your smartphone screen. If you want to be mindful of your health when buying a pre-cooked chicken, food safety experts suggest focusing on real factors rather than checkout lights: 1. Temperature & Time: Bacteria multiply quickly if chicken drops into the "danger zone" (between 40°F and 140°F). Always check the packaging timestamp and pick a chicken that hasn't been sitting out for more than four hours. 2. Plastic Packaging: Some health advocates note that letting hot, oily foods sit in plastic bags or containers for long periods can cause small amounts of plasticizers to leach into the food. If this concerns you, transfer the chicken to a glass dish as soon as you get it home.
