There is no bacterial contamination in Zamzam water. Three different samples of Zamzam drinking water were collected from public drinking tanks in the prophetic masjid in Al-Madinah, Saudi Arabia. All water samples were centrifuged. No sediment was seen. A drop of each water sample was immediately placed on CLED agar plate and allowed to be incubated for 48 hours at 37°C. No bacterial growth was there.
