How long can marinated pork loin in a zip lock bag sit out before grilling?

It is not recommended to leave marinated pork loin in a zip lock bag out at room temperature for more than 2 hours. At room temperature, bacteria can grow rapidly and cause food to become unsafe to eat.

If you need to marinate the pork loin for a longer period of time, it is best to refrigerate it. You can marinate the pork loin for up to 2 days in the refrigerator, or up to 5 days if it is vacuum-sealed. When you are ready to grill the pork loin, thaw it in the refrigerator overnight or under cold running water if you are short on time.

When grilling the pork loin, be sure to cook it to an internal temperature of 145 degrees Fahrenheit. This can be checked using a meat thermometer.
