Daily mortality + egg-production HPAI surveillance round — London, England.

London, England is a global headquarters city of Springer Nature -- which publishes Scientific Reports (via its Nature Portfolio imprint), the exact journal this standard's foundational citation (Gonzales JL, Elbers ARW. Sci Rep. 2018;8:8533) appeared in, already confirmed via WebFetch to Wikipedia earlier this session for a separate standard. No honesty-limit caveat needed: Springer Nature is the direct publisher of the citation's own journal. Distinct from the existing Ames tile (university-based NAHLN lab), Reynoldsburg tile (state department of agriculture lab), and Washington DC tile (USDA's own national headquarters) -- London is the journal's own publishing headquarters, a genuinely separate reuse of the city from this session's earlier feline_grimace_pain_screen tile, since that connects to a different standard's own distinct citation in the same journal.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

A dated daily mortality count per flock/house compared against the fixed (>0.08%/>0.13%) and ratio (>2.9x prior-week average) thresholds; for layer flocks, weekly egg-production ratio also tracked against the <0.94 confirmation threshold; any threshold breach sustained 2 consecutive days, OR any bird with acute HPAI-consistent signs at any time, reported immediately to the relevant animal-health authority

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• A daily mortality-count log per flock/house (paper or app), with housing system (indoor barn vs free-range) recorded
• A weekly egg-collection count log for layer flocks
• The state veterinarian's contact information and the USDA toll-free reporting line (1-866-536-7593), posted where the counter will see it

Steps

1. 1. Count and record all mortalities per flock/house at the same time each day.
2. 2. Note the housing system (indoor barn vs free-range) per flock, since the fixed mortality threshold differs (0.08% vs 0.13%).
3. 3. Compute the daily mortality percentage (deaths / flock size) and compare against the fixed threshold for that housing system.
4. 4. Compute the ratio of today's mortality to the average daily mortality of the PRIOR week, and compare against the 2.9x ratio threshold.
5. 5. If EITHER threshold (fixed or ratio) is exceeded, note the date; a single day over threshold is monitored closely but not yet a trigger.
6. 6. If the threshold is exceeded for a SECOND CONSECUTIVE day, treat as a positive screen and proceed to the egg-production confirmation step (or, for non-layer flocks, report directly).
7. 7. For layer flocks, compute the weekly egg-production ratio (this week's production / expected or recent-baseline production) and compare against the <0.94 confirmation threshold.
8. 8. If the mortality screen is positive (step 6) AND the egg-production ratio is below 0.94, report IMMEDIATELY to the state veterinarian or USDA's toll-free line (1-866-536-7593).
9. 9. Regardless of any numeric threshold, any bird showing acute HPAI-consistent signs (sudden death, respiratory distress, swelling of the head/neck, neurological signs, diarrhea) is reported IMMEDIATELY -- never wait for the 2-day sustained threshold or the egg-production confirmation when acute signs are present.

What counts as done

• Daily mortality count per flock/house, with housing system noted (indoor barn vs free-range, since the fixed thresholds differ)
• Mortality compared against BOTH the fixed threshold (>0.08% indoor / >0.13% free-range) and the ratio threshold (>2.9x the prior week's average daily mortality)
• For layer flocks, weekly egg production tracked and the ratio compared against the <0.94 confirmation threshold
• Any threshold breach sustained for 2 consecutive days, OR any bird showing acute HPAI-consistent signs (sudden death, respiratory distress, swelling, neurological signs) at any time, reported IMMEDIATELY to the relevant animal-health authority

Proof is measured against these, not judged by taste.
