§ 100870 Laboratory Proficiency Testing Requirements

This law says any lab that is ELAP certified or TNI accredited (or applying for those) must test special proficiency samples a few times each year to prove they can accurately check food for pesticide residues.

Key Takeaways

  • •Certified or accredited labs must test proficiency samples when they’re available.
  • •They must test the samples 2 to 4 times a year.
  • •If the state board identifies itself, labs submit results on the board’s form, on time, and the board pays nothing for the analysis.
  • •If the board stays anonymous, the lab can charge the board for the work.
  • •Faking results from another lab will cause immediate loss of certification or accreditation.
  • •Labs must get samples from providers that meet TNI standards and pay any study fees, while allowing the provider to send the report directly to the state board.

Example

A food testing lab that is ELAP certified receives two proficiency testing sample sets from the state board this year, runs the tests using approved methods, and sends the results back on the board's form by the deadline.

Because the lab is certified, it must analyze the samples, submit the results on time, and it won’t be charged for the analysis since the state board identified itself.

§ 100870 Laboratory Proficiency Testing Requirements

(a) Any laboratory that is ELAP certified or holds TNI accreditation or has applied for ELAP certification or TNI accreditation or for renewal of ELAP certification or TNI accreditation under this article shall analyze proficiency testing samples, if these testing samples are available. The state board shall have the authority to contract with third parties for the provision of proficiency testing samples for those laboratories that hold or are applying for ELAP certification. The samples shall be tested by the laboratory according to methods specifically approved for this purpose by the United States government or the state board, or alternate methods of demonstrated adequacy or equivalence, as determined by the state board. Proficiency testing sample sets shall be provided, when available, not less than twice, nor more than four times, a year to each certified laboratory that performs analyses of food for pesticide residues. (b) (1) The state board may provide, directly or indirectly, proficiency testing samples to a laboratory for the purpose of determining compliance with this article with or without identifying the state board. (2) When the state board identifies itself, all of the following shall apply: (A) The results of the testing shall be submitted to the state board on forms provided by the state board on or before the date specified by the state board, and shall be used in determining the competency of the laboratory. (B) There shall be no charge to the state board for the analysis. (3) When the state board does not identify itself, the state board shall pay the price requested by the laboratory for the analyses. (c) If a certified or TNI accredited laboratory submits proficiency testing sample results generated by another laboratory as its own, the certification or TNI accreditation shall be immediately revoked. (d) Laboratories shall obtain their proficiency testing samples from proficiency testing sample providers that meet TNI standards. Laboratories shall bear the cost of any proficiency testing study fee charged for participation. Each laboratory shall authorize the providers of proficiency testing samples to release the report of the study results directly to the state board, as well as to the laboratory. (Amended by Stats. 2017, Ch. 327, Sec. 13. (AB 1438) Effective January 1, 2018.)
