SALINAS, CA -- California and Arizona, the two largest lettuce-producing states, account for more than 95% of the lettuce grown in the United States. Since the early 1990s, the states' lettuce crops have been subject to "dieback", a disease indicated by symptoms including mottling, yellowing, and death of older leaves, and stunting and eventual death of lettuce plants.

Food safety is an issue that won’t go away — and that’s a good thing for retailers and consumers of California table grapes. All major grape grower-shippers have implemented comprehensive food safety programs, and they show no signs of letting their guard down.
