Eva Longoria-backed migrant doc out Tuesday on DVD

Eva Longoria says she lent her support to "The Harvest," a documentary about child migrant laborers, not just because of her Latin American roots but also because she wants to know where her food comes from and take responsibility for it.
Much of the harvesting work in the United States is done by migrants from Latin America, especially Mexico. But Longoria's interest in the subject didn't spring from her common roots, but from concern over children growing up in the fields, the "Desperate Housewives" star says.
"I'm ninth-generation Mexican-American. We have ranches in Texas but you don't have to have that to have compassion," Longoria said. "I eat food and I'm a responsible human being and if you are responsible, you have to know where your food comes from."
Longoria said a quarter of food eaten in the United States is harvested by children. That estimate could not be immediately confirmed by The Associated Press. Human Rights Watch reported in 2010 that a "significant proportion" of hired farm laborers in the United States were under 18, but said that accurate numbers were hard to come by.
The documentary says that more than 400,000 children work in U.S. farm fields.
"You have to be aware of the practices that are used to get the food we are eating," Longoria said in a phone interview from the set of "Desperate Housewives," now shooting its final season. She is the executive producer of "The Harvest" and raised nearly $1 million for the film, which will be released on DVD Tuesday.
"I've been involved with farm workers advocacy for a long time," she said, "but I recently found out, I didn't know there were so many children working legally in the fields."
"The Harvest" tells the story of three children who work as field laborers to help their parents.
In the film, one of them, 12-year-old Zulema Lopez, notes that she started working at such a young age, she doesn't even remember her first day. She adds that picking onions from 5 a.m. to 5 p.m., she made $64 a week.
The child field workers work under an unforgiving sun and in paralyzing cold and run the same risks and suffer the same deprivations as adult laborers, the film shows. Lopez, for example, recounts how she had to throw dirt on a wound to stop it from bleeding. The film also explains how migratory work makes it difficult for children to receive a proper education.
The film has been shown to members of Congress to promote a bill sponsored by Rep. Lucille Roybal-Allard, a Democrat from California, that would raise the minimum age for field work in the U.S. from 12 to 14 years. It also seeks to create penalties for labor infractions against young field workers and reduce their exposure to pesticides.
"We want to use the film to change policy," Longoria said. "Children shouldn't have to choose between school and work."
