Pathogen Elimination


Pathogen Elimination

The elimination of pathogens in manure is a primary benefit of the anaerobic digestion process.

Poultry manure and other livestock wastes are known to contain many pathogens which could potentially contaminate surface water, groundwater and soil.  Alexander et al. (1968) tested 44 poultry litter samples for the presence of pathogens. They found 10 different species of Clostridium, 3 species of Salmonella, 2 species of Corynebacterium, 1 species of yeast, and 1 species of Mycobacterium (which is occasionally responsible for tuberculosis) in various litter samples. All of the litter samples contained Enterobacteriaceae (other than Salmonella), Bacillus spp., Staphylococcus spp., and Streptococcus spp. In Arkansas, the nation’s leading poultry producing state, 90 percent of the surface water bodies (statewide) sampled recently by the Arkansas Department of Pollution Control and Ecology contained fecal coliform counts in excess of the primary contact standards.

Food-safe fertilizerPoultry manure has long been known to be an excellent fertilizer, full of nutrients and organic matter that are beneficial for plants and soil.  However, it can be harmful to farmers, consumers, and the ecosystem if it is not properly treated.  BioStar’s patent pending technology guarantees production of chicken manure organic fertilizers which are safe to handle and safe to use on food crops!

BioStar’s high-temperature anaerobic digestion process has been validated to provide the following destruction efficiencies:

  • Cryptosporidium – Virtually complete destruction
  • Giardia – Virtually complete destruction
  • Salmonella – Virtually complete destruction
  • Escherchia coli – 99.9999% reduction
  • Fecal coliforms – 99.999% reduction
  • Fecal streptococci – 99.999% reduction
