Paper Abstract

Efforts were made to incorporate the phage Magnetoelastic (ME) biosensor in FDA's Spinach Soaking procedures according to FDA 2015 BAM method. Three soaking materials (Lactose broth, LB broth, and Peptone water) and various soaking times were investigated. Using merely 100 Salmonella cells spiked on the produce surfaces, the phage biosensors detected Salmonella within 5 hours when soaking tomatoes in LB broth as opposed to taking up to 24 hours. Salmonella was detected on spinach leaves within 7 hours. These phage ME biosensors provide a promising rapid detection platform using LB broth in FDA's soaking procedures while shortening the incubation period.
