Food Safety: Green and Clean Approaches - Studying Microbial Contamination of Produce and Other Foods from Farm to Fork
Contamination Routes and Stressors Being Explored
Studies Being Conducted
Food Microbiological Testing in Dr. Sadhana Ravishankar's Laboratory
Price List below - note that price listing does not include administrative fee of 18%; administrative fee is not charged to UA departments. Consulting fees are also not included.
This test results in an enumeration of the total aerobic bacterial population of a sample. The results can be applied to internal acceptance criteria for a product or environmental HACCP samples. Environmental surface samples can also be analyzed.
Antimicrobial effectiveness test is a valuable tool for evaluating either intrinsic antimicrobial properties, or different types and levels of added antimicrobial agents. We can test the efficacy of any type of antimicrobial agent.
To ensure that the sanitation procedure is being performed effectively validation should be done periodically. We can analyze for basic microbial contaminants to verify proper cleaning.
Microbial Shelf-life Studies
We can test the effects of microbial load on product’s shelf life for various types of foods including fresh produce, juices, meats and poultry, seafood, and dairy products.
Total Coliforms & E. coli
Coliforms are often referred to as indicator organisms, their presence in the environment can indicate that conditions are favorable for pathogens to be present. The presence of generic E. coli in a sample indicates fecal contamination. The Total Coliform/E. coli test is a fast inexpensive way to assess the cleanliness of an environment or food, and can also be used to collect information regarding the potential for other contamination.
Screening for Foodborne Pathogenic Bacteria
We can perform several foodborne pathogen screens from foods including:
• Escherichia coli O157:H7
• Salmonella enterica
• Listeria monocytogenes
• Staphylococcus aureus
• Campylobacter jejuni
• Enterobacter sakazakii
Surface and Air Sampling
We can perform sampling for microbial contaminants on various food contact surfaces and in the processing environment (air).
We can analyze the aflatoxin content in various food products.
Sensory Evaluation of Food Products
The sensory quality of a food product is the most important factor influencing its success in the marketplace. We can test the consumer acceptability of a food product by using trained and untrained panels of various ages.
We can publish, deliver and promote research results by posters, demos/displays at community events, seminars and workshops.
