Ag researchers address recalls, food safety at holidays

NASHVILLE, Tenn. (TSU News Service) – Tennessee State University researchers in the College of Agriculture have some pertinent food safety information for consumers amid recent recalls and the bustling holiday season.

Last month, there was a recall of romaine lettuce after a multistate outbreak of E. coli infections were linked to the lettuce, according to the Centers for Disease Control and Prevention. There was a similar ground beef recall in June.

Dr. Agnes Kilonzo-Nthenge is an associate research professor in the College of Ag’s Department of Human Sciences at TSU. She says whenever there’s a recall, consumers should take them seriously.

“It is important for consumers to listen to the news and be aware of food recalls,” says Kilonzo-Nthenge. “Some of the recalled products may be in our homes.”

In the last year, TSU’s College of Agriculture has received more than a million dollars for food safety research.

Kilonzo-Nthenge is the principal investigator for a $450,000 grant from the U.S. Department of Agriculture to pursue an integrated approach to mitigate antimicrobial resistance in cattle and poultry, and help establish stewardship programs for small and medium-sized ranchers.

“Consumers are educated on safe handling practices at home and our farmers are trained on good agricultural practices that prevent or reduce meats and fresh produce contamination with pathogenic bacteria that might be resistant to antibiotics,” says Kilonzo-Nthenge.

Dr. Ankit Patras, a research assistant professor of agricultural science, also recently received two grants totaling more than $650,000 from the USDA National Institute of Food and Agriculture, Trojan Technologies of Canada, and California-based Aquafine Corporation. The grants are funding research to make food safer by eliminating harmful viruses and bacterial endospores in juices and other beverages.

“An important aspect of the study is to create science-based knowledge and bridge existing knowledge gaps by assessing the sensitivity of target foodborne viruses and spores to this treatment,” says Patras, the principal investigator. “We want to identify markers of oxidative stress, which can be correlated to microbial inactivation.”

This holiday season, TSU researchers say there are some simple ways to avoid foodborne illnesses. They include:

  • Wash hands and surfaces after handling raw meats.
  • Keep raw meat and poultry apart from freh produce and foods.
  • Preheat the oven to 450 degrees Fahrenheit, then lower temperature to 350 F when putting turkey into the oven. Cook for at least 2 hours and 30 minutes. Turkey is done when it registers a minimum of 165 F in the thickest part of the thigh.
  • Hot or cold food should not be left out for more than two hours. Bacteria grow rapidly in the range of temperatures between 40 F and 140 F, doubling in as little as 20 minutes.
  • Hot foods should be kept at a temperature of at least 140 F.
  • Cold foods, such as chicken salad or potato salad, should be kept cold, at or below 40 F.

USDA awards $450K to College of Agriculture for food safety research

By Joan Kite

 NASHVILLE, Tenn(TSU News Service) – Tennessee State University has been awarded $450,000 from the U.S. Department of Agriculture for food safety research.

Dr. Agnes Kilonzo-Nthenge

The grant from the USDA’s Agricultural Food and Research Initiative will be used by TSU’s College of Agriculture to pursue an integrated approach to mitigate antimicrobial resistance in cattle and poultry, and help establish stewardship programs for small and medium-sized ranchers.

“We’re delighted that we’re able to get funding to continue our research and outreach projects on antimicrobial resistance of microorganisms in agricultural lands,” said Dr. Agnes Kilonzo-Nthenge, an associate research professor in the College’s Department of Human Sciences and the grant’s principal investigator. “Our goal is to educate small and medium-sized cattle and poultry producers to better understand antibiotic resistance factors on farms and maximize their profits in their production systems.”

The emergence of antimicrobial resistant pathogens in animal production systems has become a major challenge to public health. Every year, at least 23,000 people die in the United States due to infections caused by microorganisms that are resistant to antibiotics, according to the Centers for Disease Control and Prevention.

Consumers’ increasing demand for antibiotic-free meat is influencing meat producers and processors to find other ways to provide meat that is both free from disease and antibiotics. The Food and Drug Administration, responding to concerns about antibiotic-resistant bacteria, is working with drug and meat companies to find alternative ways to keep livestock healthy and meat safe for the consumer.

“Unless small and medium-sized producers are provided with the latest knowledge from scientific research and education in judicious use of antibiotics, they will not be competitive in the meat industry,” said Dr. Kilonzo-Nthenge.

“A comprehensive understanding of best management practices and the correlation between antibiotic-resistant bacteria and the use of antimicrobials in agriculture is vital in developing strategies and interventions to minimize the spread of resistance. We can help the farmer choose production methods that will reduce risk of disease in their livestock while ensuring their profits.”

TSU officials say the research is timely, considering the foodborne outbreaks that have been occurring in certain parts of the country. Earlier this month, the CDC announced a multistate outbreak of salmonella linked to pre-cut melons. Before that, there was a recall on Romaine lettuce contaminated with E. coli.

TSU’s College of Ag held two workshops this month to address food safety and recently added several professors to do research in that area.

“TSU is taking the lead … to see what is really causing those outbreaks, and how we can prevent them,” said Dr. Ankit Patras, one of the new Ag professors and workshop organizer.
