Project Type: Trust Fund Cooperative Agreement
Start Date: Sep 1, 2020
End Date: Sep 30, 2022
1) Assess effectiveness of various sanitizing compounds in reducing microbial (Salmonella, Campylobacter, Listeria, Enterobacter cloacae) counts. Microorganisms used in this study would originate from isolates obtained from a previous study, which sampled various egg processing facilities around the United States. These isolates would best reflect what is currently found in egg processing facilities. 2) Assess effectiveness of various sanitizing compounds in breaking down or penetrating egg residue and/or biofilms (visual and microbial assessment).
Key equipment parts such as belts, rollers, egg carriers, flaps, and egg non-contact surfaces such as sealed and unsealed concrete would be tested under various soiled conditions (clean surface, diluted egg contents and spiked diluted egg contents). Soiled equipment and surfaces would be created by exposing the equipment parts and surfaces to diluted egg contents (non-inoculated/inoculated) and allowing the egg contents solution to adhere and dry before the application of the sanitizing compounds.
