Overview of Research Program
 
Delineation of the contribution of non-thermal factors (pH, ammonia, organic acids, light, and moisture) to zoonotic pathogen inactivation in composts containing animal manure as a primary ingredient
Surface contamination and internalization of E. coli O157:H7 and Salmonella spp. in leafy greens under field conditions and the environmental parameters that lead to increased risk of contamination of produce at harvest
Instrumental (Znose) headspace analysis for spoilage assessment of Clostridium botulinum-inoculated salmon stored at refrigerated and abusive temperatures under air, vacuum, and modified atmospheres
