Kindly clarify please. Infection?

If I drink anything say that may be contaminated or eat anything and after 2-3 minutes blow my nose moderately or vigorously to expel irritants or if I inhale deeply once or twice by mistake. Is it possible that the contaminated food or water can get in up deep in my nasal passages or near the olfactory nerves to cause N Fowleri infection? When I talk about inhaling it means a bit deep but not like when we do so in deep breathing. Please I request you to clarify this doubt. I have asked many times but I won't ask about this again if someone can please clarify this for me. Then I will only worry about avoiding swimming in warm freshwater sources, diving in them as I don't use Neti pots. I will be very thankful.
