My interest is in the aspect of pathogen flow. You did mention that your first test was pathogen free. Your result of course would depend on what kind of test you conducted. I do know that many of the human faecal pathogens are parasitic, which you may not be able to detect in your observation wells. Some of these can form cysts which mix well with your manure, and can reinfect man. There have been reports of outbreak of Ascariasis in a Community where such compost had been applied for growing vegetables. But I guess your laterine waste must have been adequately digested. In trying to check the pathogen flow, the engagement of a Parasitologist, is as important as that of a Microbiologist,since you are dealing with human health.

All the Best,
Christie.
