Leukocytes are classified broadly as granulocytes and agranulocytes. These terms tell you something about these cells. If a leukocyte possesses cytoplasmic granules it is a granulocyte and if these granules are lacking, it is an agranulocyte. Once this distinction is made, more specific identification can follow.
Best Answer: i would do one of the following.. The rule of thumb is 2 hours. Because lunch meat contains so much salt and preservatives, I'd eat it after 8 or 9 hours left out( and have). The chance of spoilage is of course is always there. But after just 4 or 5 hours, I would just refrigerate it. I am pretty careful about following HACCP( safe food handling and temp control) but in this case, knowing that companies pump these products, the chances are slim that they would go bad in 4 or 5 or 6 hours.
Timing Is Everything. Indoors, you can safely leave a sandwich out for up to two hours after making it, according to the USDA. After that, bacteria starts to multiply rapidly. In hot weather the margin of safety is cut to one hour. Don't take chances. Refrigerate sandwiches or pack your lunch box with an ice pack.
