Microbiologist Specializes in Food Processing and Science and Food Safety

Technical Consultant #1092


Expertise

  • Microbiological challenge experimental design study.
  • HACCP development, microbiological validation and verification.
  • Thermal food processing, food chemistry and food ingredients.
  • Relationship between food matrix and pathogenic bacteria growth, survival and toxin production.
  • Working with strict anaerobic bacteria including C. botulinum and C. sporogenes and other food borne pathogens including L. monocytogenes, E. coli 0157:H7, and Salmonella.
  • Time-Temperature relationship in the thermal destruction of food borne bacterial pathogenes.
  • Microbiological food safety audits.

Experience

Hershey Foods 1998 - Present

Associate Staff Scientist

  • Technical support and leadership to product development projects involving new product development, product improvement, plant quality assurance issues, process optimization and food safety issues.
  • Plant QA in the development and implementation of HACCP plans, environmental hygiene monitoring programs and GMP.
  • Conduct and supervise microbiological validation and verification studies of key processes and programs to ensure food safety.
  • Conducted studies relating food fill temperature microbiological content and stability.

Assistant Staff Scientist 1995 - 1998

  • Manufacturing plant audits to ensure that processing lines and equipment are adequately cleaned and sanitized, including the quality of cleaning procedures and effectiveness of chemical cleaning agents.
  • Developed and provided technical assistance to the implementation of ATP bioluminescence as a rapid tool for measuring cleanliness of washed and sanitized food contact surfaces.

Senior Research Scientist 1992 - 1995

  • Identified the potential of ATP bioluminescence as a rapid analytical tool for determining the effectiveness of processing equipment cleaning and sanitization.
  • Conducted trouble shooting studies in the plant which resulted in the establishment of hygiene monitoring programs.

Rutgers University , Research Associate 1990 - 1992

  • Isolated and identified bacteriocin producing lactic acid bacterial strains with antibotulinal activities.
  • Studied the effect of nisin on Clostridium botulinum; the mechanism of nisin inhibition was elucidated.

Memphis State University, Postdoctoral Research 1989 - 1990

  • Studied the microbiology of wetlands and the role of bacteria in the oxidation of ferrous ions in wetlands impacted by acid-mine drainage.

Penn State University/USDA ERRC, Research Assistant, Philadelphia 1983 - 1989

  • Demonstrated the inability of minimally processed mushrooms to support growth and toxin production by endogenous mesophylic and psychrotrophic C. botulinum spores.
  • Developed an acid-blanch-chelation (ABC) process for canned mushrooms. Found that acid blanched mushrooms maintain superior color quality and incorporation of chelating agent in the brine inhibited the germination and out-growth of proteolytic Clostridium botulinum spores.
  • Elucidated the mechanism of inhibition of C. botulinum spores by the ABC process.

Honors & Publications

  • 13 patents
  • Member, The Institute of Food Technologists, American Society of Microbiology, Honor Society of Agriculture, Honor Society of Food Science
  • Ad Hoc Reviewer J. Food Safety and National Research Initiative Competitive Grants
