Lo mein, a delectable Chinese noodle dish, is a popular choice for both dine-in and takeout meals. However, the question of “how long can you leave lo mein out” is crucial to ensure food safety and prevent potential health hazards. This comprehensive guide will delve into this topic, providing essential information to help you make informed decisions about consuming leftover lo mein.

Foodborne Bacteria and Lo Mein

Lo mein, like other cooked foods, can become a breeding ground for bacteria when left out at room temperature. Common culprits include Staphylococcus aureus (staph), Escherichia coli (E. coli), and Bacillus cereus, which can cause a range of symptoms from mild discomfort to severe illness.
