Summer Food Safety Alert Sushi Express

During the summer months, food poisoning incidents occur frequently, particularly when raw or cold foods are improperly handled, leading to bacterial growth that threatens consumer health. The investigative team from "Frontline Investigation" recently uncovered that Sushi Express left pre-made sushi rice outside refrigerator for over 16 hours without temperature control.  According to the guidelines from the Food Safety Center, cooked rice should cool from 60°C to 20°C within two hours and should drop to 4°C or lower within four hours after cooking. Additionally, the pH level of sushi rice should be maintained at 4.6 or below. Associate Professor, Prof. Amber Chiou from our department was interviewed by HOY News × i-Cable News, highlighting that this handling method is inappropriate. If bacteria proliferate, their toxins cannot be eliminated even with high-temperature cooking. Staphylococcus aureus and Bacillus cereus are the most common foodborne pathogens that are associated to rice products. The toxins produced by these pathogens cannot be 100% eliminated through heating. 🧫🦠 Prof. Chiou advises consumers to pay close attention to the condition of sushi rice when purchasing. If the rice grains are too dry or exhibit a stringy texture, it may indicate prolonged storage or excessive bacterial growth, and should be avoided. Let’s all prioritize food safety and protect our health!
