Blue Diamond Growers, a major cooperative in northern California is recalling 175 tons of almonds because of potential contamination with Salmonella.  The pathogen was detected following internal microbiological quality control.  Recalled products were distributed in western states, but also exported to Germany, Morocco and Canada.  The magnitude of the recall indicates that product sampling should be intensified with smaller batches examined prior to release. This would obviate the expense of large recalls. 

Contamination of nuts with Salmonella and STEC is inevitable, and the industry will have to develop a positive kill step for bacteria in their processing.  Nuts should be compatible with electron beam processing that would ensure freedom from common non spore-forming bacteria.  As with all suggested applications of an irradiation process, consumer acceptance through education will be the limiting factor.
