In this episode of Food Safety Matters, we speak to Laura [14:39] about:

• CDC's role in foodborne outbreak investigations
• How CDC works with the U.S. Food and Drug Administration and the U.S. Department of Agriculture
• Pulsed-field gel electrophoresis vs. whole-genome sequencing, and why the former is no longer the standard method for DNA fingerprinting when investigating a foodborne outbreak
• How outbreak investigations become more or less complicated depending on what type of food product is involved
• Changes and advancements coming to food safety within the next 5–10 years
