How do you keep the Spirulina ponds free of bacteria and other algae, given that they are open to the air?
The Spirulina culture grown by Earthrise is almost 100% pure because the growing medium is of such a high pH that very few other algae can survive in it. Earthrise also uses a proprietary culture control method to avoid contamination by other algae. As with other wholesome fruits and vegetables, the very low levels of natural bacteria that may be present are not harmful to human health. Earthrise Spirulina is free from harmful bacteria like E. coli, Staphylococcus and Salmonella.
