The tender leaves of this young spinach plant from King George County, Virginia, will make a tasty and nutritious salad for some lucky diner, but it's difficult to view them without thinking about recent headlines and nationwide recalls of spinach from three California counties. It's not unusual these days to read about outbreaks of food poisoning from tainted produce, and indeed, such outbreaks are more common than ever. Why is this, and what can consumers do about it? In "Safer Salads," Jorge M. Fonseca and Sadhana Ravishankar answer these questions and provide insight into the current and future steps that growers can take to combat microbial contamination. The authors include a handy list of "dos and don'ts" that should help home chefs to minimize the risk of contracting foodborne illnesses such as Salmonella or E. coli O157:H7. (Photograph by P.
