"MOSS LANDING, Calif. — With piles of fresh strawberries beckoning consumers at markets and stores this season, an alliance of a major retailer, fruit growers and farm workers has begun a program to promote healthy produce and improve working conditions."

"The initiative, unfolding along neatly planted rows of berries at the Andrew & Williamson Fresh Produce’s Sierra Farm here, is an effort to prevent the types of bacterial outbreaks of salmonella, listeria or E.coli that have sickened consumers who ate contaminated cantaloupes, spinach or other produce.

One of the workers, Valentin Esteban, is on the front lines of the new effort, having gone through a training program that helps him avoid practices that lead to possible bacterial contamination that could undermine the safety and quality of the strawberries he picks."
