(a) Any such policy shall include:
1. Notifying the Commission within 72 hours of any laboratory testing results indicating that the contamination cannot be remediated and disposing of the Production Batch submission of any information regarding contamination immediately upon request by the Commission; and
2. Notifying the Commission of any information regarding contamination as specified by the Commission or immediately upon request by the Commission.
(b) The notification shall be from both the MTC and the Independent Testing Laboratory, separately and directly.
(c) The notification from the MTC shall describe a proposed plan of action for both the destruction of the contaminated product and the assessment of the source of contamination.
(5) An MTC shall maintain the results of all testing for no less than one year. Testing results shall be valid for a period of one year. Marijuana and Marijuana Products with testing dates in excess of one year shall be deemed expired and may not be dispensed, sold, Transferred or otherwise conveyed until retested.
(6) The sale of seeds is not subject to these testing provisions.

(12) A Licensee that receives notice that Marijuana or a Marijuana Product it has submitted for testing has failed any test for contaminants shall either reanalyze the Marijuana or Marijuana Product without remediation, take steps to remediate the identified contaminants or dispose of the Marijuana or Marijuana Product.
(a) Reanalysis by a Second ITL. If the Licensee chooses to reanalyze the sample, a sample from the same batch shall be submitted for reanalysis at the ITL that provided the initial failed result. If the sample passes all previously failed tests at the initial ITL, a sample from the same batch previously tested shall be submitted to a second ITL other than the original ITL for a Second Confirmatory Test. To be considered passing and therefore safe for sale, the sample shall have passed the Second Confirmatory Test at a second ITL. Any Marijuana and Marijuana product that fails the Second Confirmatory Test may not be sold, transferred or otherwise dispensed to Consumers, Patients or Licensees without first being remediated. Otherwise, the MTC shall dispose of any such product.
(b) Remediation. If the Licensee chooses to remediate, a new test sample shall be submitted to any licensed ITL, which may include the initial ITL, for a full-panel test. Any failing Marijuana or Marijuana product may be remediated a maximum of two times. Any Marijuana or Marijuana product that fails any test after the second remediation attempt may not be sold, transferred or otherwise dispensed to Consumers, Patients or Licensees. The MTC shall dispose of any such product.
(c) If the Licensee chooses to dispose of the Marijuana or Marijuana Products, it shall do so in compliance with 935 CMR 501.105(12).
