Storing spinach for long periods of time in the refrigerator can also lead to the formation of nitrite that causes diarrhea and vomiting, so it is preferable not to store spinach for long periods. Spinach residue requires special treatment, as it must be placed in the refrigerator as soon as possible and then heated in a bowl for at least two minutes at a temperature of 70 ° C.
