Zucchini cannot survive at room temperature after being cooked for more than 3 hours. Thus, if it is cooked and some portion is left over in the bowl to be consumed later, it must be stored properly. It is required to be covered by a lid and then kept in lower temperatures to prevent its degradation. Putting them in an airtight container is highly helpful in longer preservation.

The zucchini stored at 40 to 50 degrees of Fahrenheit starts decaying after 48 hours even in the fridge as the molds start growing on it.

Thus it is not recommended to intake the discarded dish prepared by using zucchini.

Even when zucchini is stored below 5 degrees Celsius it is not recommended to intake it because it may cause chilling injury shortening the shelf life of food items.

Zucchini is a delicacy with a high nutritional quotient but demands proper storage. If stored carelessly, it may not serve the purpose for which it has been bought. To maximize the shelf life, it must be stored properly in an airtight container if cooked and in a perforated storage bag if it is to be kept raw.

Such a leftover zucchini must not be eaten to prevent gastric sickness.
