Survival of Salmonella typhimurium pathogens was followed in the slurry solid fraction from a pig farm waste water treatment plant. The tested S. typhimurium pathogens have survived for 117 days. The solid fraction was kept in the laboratory at 20-23 deg C. Indicatory microorganisms at the beginning of the experiment numbered 10**8-10**9 CFU in 1 ml sample. This number decreased by 4-5 series throughout the experiment, except for faecal coliform bacteria, which were not detected after 43 days of cultivation. Enterobacteria showed a decreasing tendency until day 83, however, on the final sampling (day 117) their count was almost double.
