On Tuesday, the U.S. Department of Agriculture's Food Safety and Inspection Service announced the Bar-S Foods Company in Altus, Oklahoma, has initiated a voluntary recall of more than 370,000 pounds of chicken and pork hot dogs and corn dog products due to possible Listeria contamination. Though no cases of contamination were confirmed, past issues with Listeria prompted the recall as a precautionary measure.
Kendra Nightingale, an associate professor in the Texas Tech University Department of Animal and Food Sciences, is an expert in Listeria and focuses her research mainly on food safety during pre-harvest and post-harvest time periods.

- Possible topics of conversation could include the incidence of listeriosis, the general characteristics of Listeria and Listeria monocytogenes and the use of combined testing and molecular sub-typing to understand the ecology of Listeria in the processing plant environment.
- Specifically, she can discuss how some Listeria monocytogenes strains appear to persist in the processing plant environment while others seem to be transient.
- "Persistent strains pose the greatest risk for cross-contamination of ready-to-eat foods such as hot dogs when the product is exposed to the processing plant environment following the lethality treatment."
