Toxocaratransmission to humans, especially children. The status of soil contamination with
Toxocaraeggs in southern Thailand is unknown. This study aimed at estimating the soil contamination with
Toxocaraeggs in public schools in Nakhon Si Thammarat province in southern Thailand. Soil samples were collected from 12 public schools between August and September 2017. At each site, ten soil samples were collected from the following five types of locations: (1) playgrounds, (2) football fields, (3) sidewalks, (4) schoolyards, and (5) areas around cafeterias. In total, 120 samples were examined for
Toxocaraeggs with a modified flotation method using a sucrose solution.
Toxocaraeggs were detected in 8 (66.7%) of the 12 studied public schools. Of the 120 soil samples, 22 (18.3%; 95% CI: 11.9, 26.4) were contaminated with
Toxocaraeggs. The highest levels of
Toxocaraegg contamination were observed in playgrounds (41.7%; 95% CI: 22.1, 63.4), followed by football fields (20.8%; 95% CI: 7.1, 42.2), sidewalks (12.5%; 95% CI: 2.7, 32.4), and schoolyards (12.5%; 95% CI: 2.7, 32.4). There were significant differences in the distribution of
Toxocaraeggs across location types

. The findings demonstrated that the soil samples from public schools were contaminated with
Toxocaraeggs. Playgrounds were the most heavily contaminated locations. Teaching children proper handwashing steps and discouraging geophagia should be implemented to reduce the distribution of
Toxocaraand limit future
