Improving farm biosecurity: testing disinfectants against parasite eggs

Parasites such as Ascaris suum in pigs and Eimeria tenella in poultry cause serious health and production problems on farms. Treating infected animals is costly and complicated, which is why prevention is essential. One of the most effective preventive measures is the cleaning and disinfection of facilities between production cycles.

Our team carried out a series of laboratory studies evaluating the effectiveness of a chlorocresol-based disinfectant against these two important parasites. For Ascaris suum, eggs were collected from naturally infected pigs, prepared under controlled laboratory conditions, and exposed to the disinfectant at different concentrations and contact times. In the case of Eimeria tenella, oocysts were obtained from poultry raised in backyard systems, carefully processed, and then tested using standardized methods

In both studies, our role covered the full chain of expertise: obtaining parasite material from the field, preparing and standardizing samples, running laboratory exposure protocols, and ensuring compliance with international guidelines. By combining field sampling with controlled in vitro assays, we provided high-quality, independent data on how disinfectants perform under realistic farm conditions.
