In this episode of Food Safety Matters, we speak with Dr. LeBeau [26:40] about:

• The Healthy Florida First contaminant testing initiative for food products, which has notably raised concerns about arsenic in candy
• Gaps around Healthy Florida First’s testing methodology, data reporting, and transparency that make the contaminant findings difficult to interpret in a scientific context
• How arsenic is typically evaluated in food products and what factors are relevant to determine whether detected levels are significant to human health
• Why detection does not always equate to danger (i.e., the difference between hazard identification and risk assessment)
• The exposure assumptions and risk calculations that are required to translate contaminant testing results into a realistic assessment of consumer risk
• How FDA and EPA typically conduct exposure science and toxicological risk assessments for contaminants in food, and how Healthy Florida First’s approach compares
• Best practices for the communication of contaminant testing results to ensure the information is accurate, transparent, and responsibly interpreted by both industry and consumers.
