What Should You Do When a Heavy Metal Result Exceeds Specification?

Review the Result

Confirm:

• metal tested;
• concentration;
• units;
• reporting limit;
• specification;
• sample identity.

Investigate Ingredients

Consider:

• botanical ingredients;
• mineral ingredients;
• supplier source;
• individual raw-material lots.

Review Sampling

If the material is heterogeneous, one small sample may not adequately represent the entire lot.

Should You Retest?

Additional testing may be appropriate, but it should answer a specific question.

Examples:

• Is the result associated with one ingredient?
• Is contamination localized?
• Do retained samples show the same pattern?
