Blood samples were obtained during a lead screening program from 100 children aged 1–6 years in Allegheny County, Pennsylvania, to determine whether there was any association between specific forms of pica and infection with , the principal cause of visceral larva migrans in the United States, or elevated blood lead levels. Significant associations were found between: 1) feces, soil, or grass pica and infection; 2) paint or plaster pica and elevated blood lead; and 3) dog ownership and infection. These findings suggest that an accurate pica history may be useful in identifying potential health problems in children.
