If left out, especially above 90°F, bacteria multiply quickly, increasing spoilage risks and compromising food safety. Always check the expiration date before use, but remember that opened almond milk requires refrigeration to stay fresh.
Sitting out too long invites spoilage, so keep your almond milk chilled and discard it if you notice any signs of spoilage. Following these guidelines helps guarantee your almond milk remains safe to consume.
