Food Microbiology Research
Dr. Trinetta's research interests include minimizing the risk of foodborne illnesses and the investigation of pathogens' survival and persistence along
the entire food supply chain.
Current projects are shown below.
Investigation of the prevalence and distribution of Salmonella in United States feed mills
Salmonella presence in feed mill environment is one of the many potential routes for pathogen transmission into the food production chain. Nevertheless, little is known about Salmonella prevalence and association in feed mills environment. The objective of this study is to investigate the prevalence and distribution of Salmonella in feed mills in different locations of United States.
Effects of different moisture and temperature on Salmonella survival in poultry fat
Limited research on strategies to eliminate pathogens in render fat is available. The mechanisms contributing to microbial presence and growth are not yet well understood. The purpose of this research is to evaluate the effects of moisture levels and storage temperatures on the growth and survival of Salmonella in poultry fat and determine death rate kinetics.
Use of Lipid Nanoemulsion-Doped Anti-Fungal Packaging Films to Control Postharvest Disease in Small Fruits
Postharvest losses can occur anywhere from harvesting to handling and shipping. it is important to find sustainable packing alternative to protect produce, increase shelf-life, minimize waste and preserve resources.The objective of this study is to evaluate the mechanical, physical and anti-fungal properties of packaging films loaded with essential oil (EO) nanoemulsions.
