Fumigating Braceros
Annotation
On arrival, the United States officials took Braceros to processing centers, searched them for, weapons, marijuana or other contraband, and sprayed them with DDT, a dangerous insecticide that is now banned. The photographer, Leonard Nadel, captioned this photograph: "Much in the same manner and feeling used in handling livestock, upon crossing over the bridge from Mexico at Hidalgo, Texas, the men are herded into groups of 100 through a makeshift booth sprayed with DDT."
