Pesticide/Neonicotinoid Sampling Chain
ActiveBiosecurityRev D
Purpose
To define the controlled sampling of pesticides, neonicotinoid residues, water, soil, and pollinator tissue so that every result is admissible, reproducible, and unimpeachable before a regulator, prosecutor, or journalist. The procedure guarantees that residue evidence implicating an adversary is collected without contamination, with an unbroken custody chain and split aliquots, so the result holds when an independent lab re-tests identical material.
Scope
All forensic pesticide and neonicotinoid sampling across field and facility operations.
In scope:
- Pre-sortie container and blank verification
- Contamination-controlled collection
- Split-aliquot sealing and preservation
- Custody transfer to the laboratory
Out of scope:
- Public release of results, which follows SOP Whistleblower & Exposure Protocol
- General custody mechanics, which follow SOP Evidence Chain-of-Custody & Handling
Definitions
Field Blank
A clean control carried through the full sampling process to prove the team introduced no contamination.
Aliquot
A divided sealed portion of a sample allowing an independent lab to re-test identical material.
Hold Time
The maximum interval and preservation condition under which a sample remains valid for analysis.
Cross-Contamination
The unintended transfer of residue between samples or from gear, which voids the affected sample.
Responsibilities
Forensics Lead (Owner)
Owns the procedure; sets the analytical standard and signs final disposition of each sample set.
Sampling Operative
Collects to standard, takes field blanks, and maintains custody to the laboratory.
HIVE-13 Legal Counsel
Confirms the admissibility standard for residue evidence.
MELISSA
Time-stamps and geotags sampling imagery and flags any custody-chain or hold-time gap.
Procedure
Pre-Sortie
- Verify all containers, field blanks, and meters against the sampling standard before departure.
- Confirm containers are residue-free and matched to the analyte; record meter calibration.
- Open the custody chain and reserve an HV-EVD reference with Evidence & Custody.
Collection
- Collect into the correct container; change gloves and clean tools between samples to prevent cross-contamination.
- Take a field blank at each site to prove no contamination was introduced.
- Photograph each sample in place with time, position, and a witness scale; MELISSA confirms the geotag.
- Split every sample into at least two sealed aliquots for independent re-test.
Preservation & Custody
- Preserve each sample to its required condition and observe the hold time through transport.
- Sign the custody chain at every transfer; an unsigned transfer voids the sample.
- Lodge the sealed set and full chain with the laboratory under the HV-EVD reference.
- Discard and re-collect rather than submit any sample with a broken seal or missed hold time.
PPE & Controls
