Resumen
The parasites infesting pigs and pig farmers on family farms in Rio de Janeiro city, Brazil,
were analyzed, and extension activities were carried out to impart information about parasites.
Between 2020 and 2021, fecal samples were collected from 180 pigs as well as ear scrapings from
142 pigs. In addition, 34 stool specimens from farmers and their families were analyzed. The collected
material was processed by parasitological techniques. Parasites were detected in 86.1% of the pigs,
forms of phylum Ciliophora (70.5%), strongylids (56.7%), Strongyloides ransomi (44.4%), coccidia
(38.3%) and Ascaris suum (32.2%). Sarcoptes scabiei var. suis were identified in 3.5% of the pigs. An
analysis of infections by age group revealed that the general frequency of phylum Ciliophora and
strongylid parasites was statistically significant. Other factors also associated with the frequency of
the parasites included the type of food fed to the pigs, cleaning of the facilities, care of piglets and
type of facility. The frequency of intestinal parasites of farmers themselves was low; however, the
high rate of parasite infections detected in pigs highlighted the precarious conditions of hygiene of
the farms. Lastly, the farmers’ participation in extension activities was a step forward in actions to
improve their farm management.
