Cost-effectiveness of lowering the aflatoxin tolerance level

Area of Science:

• Food safety analysis
• Public health economics
• Toxicology

Background:

• Aflatoxins in peanuts pose a significant public health risk, primarily liver cancer.
• Current regulatory limits for aflatoxin in peanuts are set at 20 parts per billion (ppb).
• Lowering aflatoxin tolerance levels may reduce health risks but increase industry costs.

Purpose of the Study:

• To assess the cost-effectiveness of adopting lower aflatoxin tolerance levels (15, 10, and 5 ppb) for peanuts.
• To estimate the economic impact on manufacturers and the public health benefits of reduced aflatoxin exposure.
• To inform regulatory decisions regarding peanut aflatoxin control.

Main Methods:

• Manufacturer costs for monitoring and control at various aflatoxin levels were surveyed.
• Peanut product exposure data were obtained from HANES I and production statistics.
• Liver cancer risk was estimated using epidemiological and experimental data at each tolerance level.

Main Results:

• A 15-ppb aflatoxin tolerance level is estimated to cost $60,000 per cancer death averted.
• The marginal cost per life saved for 10-ppb and 5-ppb levels increases substantially to $1.7 million and $1.6 million, respectively.
• The cost-effectiveness of the 15-ppb level is relatively favorable compared to higher reductions.

Conclusions:

• The 15-ppb aflatoxin tolerance level for peanuts demonstrates a relatively cost-effective approach to reducing cancer risk.
• Implementing 10-ppb or 5-ppb tolerance levels presents significantly higher marginal costs per life saved.
• Regulatory strategies should consider these cost-effectiveness ratios alongside alternative public health investments.
