Laboratory aerobic mesophilic stabilisation (fermentation) of pig slurry reduced the survival time of S. typhimurium, compared with their prevalence in anaerobic excrements. The decimation time T90 for S. typhimurium, was 32 hours. The effect of aerobic stabilisation on the survival of nonembryoted eggs of the model helminth A. suum was lower than that observed in Salmonella. After 54 hours of aerobic stabilization of slurry only 32 % of eggs were devitalized. Stabilized control group did not develop 13 % of eggs into their embryonated stage
