"Use By Dates" are labels found on food packaging that indicate the last day a product is safe to consume. These dates are set by manufacturers based on safety assessments and are particularly important for perishable items like dairy, meat, and prepared foods. Consuming products past their "Use By Date" can pose health risks due to the potential growth of harmful bacteria. It's important to note that "Use By Dates" differ from "Best Before Dates," which suggest when a product is at its best quality but may still be safe to eat afterward. Always check these dates to ensure food safety and minimize waste.
