With the Ghost Festival approaching, a nutritionist is advising caution regarding food offerings due to the summer heat. Food left out during the festival is prone to rapid spoilage, posing health risks. The expert recommends a three-stage preservation method: initial cooling, refrigeration, and reheating. Crucially, food must be heated to a safe temperature to eliminate potential bacteria. Proper handling and storage are essential to prevent food poisoning and ensure the safety of those consuming the offerings after the rituals. The nutritionist emphasizes prioritizing food safety alongside traditional practices during this time.
