The safe duration for keeping curd (also known as yogurt) outside the fridge depends on various factors, such as the ambient temperature and humidity. In warmer climates, curd can spoil more quickly than in cooler environments. Additionally, the initial temperature of the curd, the type of milk used, and the presence of any additives can also affect its shelf life at room temperature.
In general, it is recommended to consume curd within 2 to 4 hours if kept at room temperature. If the temperature is particularly high, it's best to consume it within 2 hours to minimize the risk of bacterial growth.
To extend the shelf life of curd, it's advisable to store it in the refrigerator. Refrigeration significantly slows down the growth of bacteria and helps maintain the curd's freshness for a more extended period. Properly refrigerated, curd can usually last for about 7 to 10 days beyond its production date, depending on the brand and any preservatives used.
If you suspect that the curd has been left out at room temperature for too long or if you notice any unusual appearance, odor, or taste, it's better to err on the side of caution and discard it. Consuming spoiled dairy products can lead to foodborne illnesses and gastrointestinal issues. Always use your senses and follow food safety guidelines to ensure the food you eat is safe and fresh.
