NEW YORK (AP) — Procter & Gamble says it's working to stop the "Tide Pod challenge," a social media-fueled trend in which teenagers eat single-load laundry detergent packets. The American Association of Poison Control Centers warned last week that it had seen a spike in teenagers eating the detergent pods, which it says can cause seizures, respiratory arrest and even death. CEO David Taylor called the trend "dangerous" and "extremely concerning" in a blog post Monday.
