LAAF-Accreditation of Laboratories

§ 1.1138 What are the eligibility requirements for a LAAF-accredited laboratory?

(a) A laboratory that is LAAF-accredited or seeking LAAF-accreditation must demonstrate it is capable of conducting each method of food testing for which it is or will be LAAF-accredited by meeting all of the following requirements:

(1) For each method, the laboratory is accredited by a recognized accreditation body to ISO/IEC 17025:2017(E) (incorporated by reference, see § 1.1101).

(2)

(i) Except as provided in paragraph (a)(2)(ii) of this section, the laboratory has successfully passed a proficiency test provided by a competent proficiency testing organization within the last 12 months for each method within the scope of LAAF-accreditation.

(ii) If the laboratory determines there is no proficiency testing program available or practicable for a method, it may use a comparison program. A laboratory must request approval from the recognized accreditation body regarding the determination prior to using a comparison program in lieu of an annual proficiency test. The laboratory is required to demonstrate competency through participation in the comparison program.

(iii) A laboratory must submit all proficiency test and comparison program results, regardless of outcome, to the recognized accreditation body within 30 calendar days of receipt.

(3) The laboratory ensures that its procedures for monitoring the validity of the results of testing it conducts under this subpart include the use of reference materials or quality control samples with each batch of samples it tests under this subpart.

(b) Will comply with all additional requirements for LAAF-accredited laboratories under this subpart while LAAF-accredited.

§ 1.1139 How does a laboratory apply for LAAF-accreditation or extend its scope of LAAF-accreditation?

(a) Application for LAAF-accreditation. A laboratory seeking LAAF-accreditation or extension of its scope of LAAF-accreditation must submit its application for LAAF-accreditation to a recognized accreditation body identified on the website described in § 1.1109. The recognized accreditation body will review and assess the application in accordance with the requirements of this subpart. If the laboratory seeking LAAF-accreditation had its LAAF-accreditation withdrawn or one or more methods within its scope of LAAF-accreditation reduced by a recognized accreditation body or has been previously disqualified by FDA, the laboratory must meet the additional requirements specified by § 1.1142(a).

(b) Documentation of conformance with ISO/IEC 17025:2017(E). The laboratory may use documentation of conformance with ISO/IEC 17025:2017(E) (incorporated by reference, see § 1.1101), as applicable and supplemented as necessary, in meeting the applicable requirements of this subpart.

(c) Duration of accreditation. If a LAAF-accredited laboratory maintains compliance with all requirements of this subpart, including accreditation to ISO/IEC 17025:2017(E), the laboratory's LAAF-accreditation will not end until reduced in scope, withdrawn, relinquished, or the laboratory is disqualified, under this subpart.

§ 1.1140 What must a LAAF-accredited laboratory do to voluntarily relinquish its LAAF-accreditation?

(a) Notice to FDA and the recognized accreditation body of intent to relinquish. A LAAF-accredited laboratory must notify FDA and its recognized accreditation body at least 60 calendar days before voluntarily relinquishing LAAF-accreditation or any method within the scope of LAAF-accreditation. The notice must include the date on which relinquishment will occur. If the laboratory will relinquish all methods within its scope of LAAF-accreditation, the notification must also include the name and contact information of the custodian who will maintain the records required by § 1.1154 after the date of relinquishment. The contact information for the records custodian must include an email address and the street address where the records required by § 1.1154 will be located.

§ 1.1141 What is the effect on a LAAF-accredited laboratory if its recognized accreditation body is no longer recognized by FDA?

If a recognized accreditation body has its application for renewal of recognition denied, relinquishes its recognition or allows its recognition to expire, or has its recognition revoked, any laboratory LAAF-accredited by the accreditation body must take either the actions in paragraph (a) of this section or the action in paragraph (b) of this section no later than 30 calendar days after receiving the notice to the LAAF-accredited laboratory required under § 1.1115(g), § 1.1116(b), or § 1.1131(d)(2):

(a)

(1) The LAAF-accredited laboratory must submit to FDA documentation of the LAAF-accredited laboratory's most recent internal audit, required under § 1.1154(a)(5), documentation showing compliance with the conflict of interest requirements in § 1.1147, and documentation of the most recent proficiency test or comparison program result for each test method within the laboratory's scope of LAAF-accreditation, to show compliance with § 1.1138(a)(2); and

(2) The laboratory must become LAAF-accredited by another recognized accreditation body before the laboratory's ISO/IEC 17025:2017(E) (incorporated by reference, see § 1.1101) accreditation lapses or not later than 1 year after the LAAF-accredited laboratory receives the applicable notice under § 1.1115(g), § 1.1116(b), or § 1.1131(d)(2), whichever is sooner.

(b) The LAAF-accredited laboratory initiates relinquishment of its LAAF-accreditation under § 1.1140, with the relinquishment to occur within 90 calendar days.

§ 1.1142 How does a laboratory request reinstatement of LAAF-accreditation?

(a) Application following reduction of scope or withdrawal of LAAF-accreditation by a recognized accreditation body or disqualification by FDA. A laboratory that has had any methods within its scope of LAAF-accreditation reduced or has had its LAAF-accreditation withdrawn by a recognized accreditation body or that has been disqualified by FDA may seek reinstatement of LAAF-accreditation by submitting a new application for LAAF-accreditation to a recognized accreditation body under § 1.1139.

(2) Demonstrate, to the satisfaction of the recognized accreditation body to which it is submitting the new application, that the grounds for the reduction of scope or withdrawal of LAAF-accreditation or disqualification have been resolved and that the laboratory has implemented measures to prevent such grounds from recurring.

(b) Application following voluntary relinquishment of LAAF-accreditation. A laboratory that voluntarily relinquished any methods within the scope of its LAAF-accreditation pursuant to § 1.1140, may seek reaccreditation by submitting a new application for LAAF-accreditation to a recognized accreditation body under § 1.1139.
