New publication on fate of Ascaris at various pH, temperature and moisture levels

A new study assessed the inactivation of Ascaris eggs under various conditions and observed that the exposure of Ascaris eggs to elevated pH (10.5–12.5) at temperatures <27.5 °C for >70 days had no effect on egg viability. To accelerate the inactivation of STH, an increase in the treatment temperature is more effective than pH increase. Alkaline pH alone did not inactivate the eggs but can enhance the effect of ammonia, which is likely to be present in organic wastes.
