Can deli sliced pastrami in a zip-lock left unrefrigerated for 16 hours at 70 degrees be safe to eat and would it need re-cooked or re-pasteurized?

According to the USDA, perishable foods, including deli meats, should not be left out at room temperature for more than two hours. This is because bacteria can grow rapidly in this temperature range, and can cause food to become unsafe to eat.

In this case, the pastrami was left out at room temperature for 16 hours, which is well beyond the two-hour limit. Additionally, the temperature was 70 degrees, which is within the range where bacteria can grow rapidly.

Therefore, it is not safe to eat the deli-sliced pastrami that has been left unrefrigerated for 16 hours at 70 degrees. It should be discarded.
