One health response to global poultry production

In the last 20 years, global poultry farming nearly doubled, from around 17 billion chickens and other poultry birds in 2002 to 28 billion in 2022, a steady increase of about half a billion chickens and other poultry birds per year (FAO 2023).

State agriculture dept. is hiding bird flu information, legal aid group alleges in lawsuit
A legal aid group that represents farm workers is suing the state agriculture department claiming it is not sharing the locations of dairies that are experiencing H5N1 bird flu outbreaks, and that has endangered the public and put workers at risk. Epidemiologists agree.

Toename in het aantal wilde vogels die doodgevonden worden met hoog-pathogene vogelgriep in Nederland. Belangrijk om dode wilde vogels te melden om een goede indruk te kunnen krijgen wat de impact is van deze ziekte op wilde vogelpopulaties: dwhc.nl/meldingsform... of sovon.nl/tellen/telpr...
Dezemaand zijn er 122 dode wilde vogels door het DWHC naar het WBVR gestuurd om te testen op vogelgriep. Er zijn nog vogels in onderzoek. Tot nu toe zijn er 57 positieve testresultaten onder dode wilde vogels gevonden: 53 eendachtigen en 4 roofvogels. Deze vogels kwamen uit de provincies Groningen, Friesland, Flevoland, Overijssel, Gelderland, Noord-Holland, Zuid-Holland, Noord-Brabant, Utrecht, en Zeeland. https://dwhc.nl/maandelijks-overzicht-van-vogelgrieptesten-2025/#custom-collapse-0-9 Dode brandgans.

Its taken a while, but a summary of our "enhanced surveillance" for HPAI that we undertook last spring is now on bioRxiv. Lots of cool LPAI viruses in arriving shorebirds, but no HPAI.

Worrying reports of bird flu (avian influenza) are coming in, including an outbreak in Whooper Swans in the Fens. Other waterbirds are also being affected, and cases are rising.

1/ Highly pathogenic avian influenza (HPAI) in Great Britain & Europe - DEFRA outbreak assessment for 28 Oct 2025. #IDsky #IDEpi #OneHealth #H5N1 🧪

🗓️ Report period: 08-28 Oct 2025

🔗 to report: assets.publishing.service.gov.uk/media/6908c1...
Department for Environment, Food & Rural Affairs Preliminary Outbreak Assessment #2 High pathogenicity avian influenza (HPAI) in Great Britain & Europe 28 October 2025 Disease report In our previous outbreak assessment on 8 October 2025 (High pathogenicity avian influenza (HPAI) in Great Britain & Europe). we noted that, although positive reports of HPAI H5 in Great Britain were falling after the summer, there was an increasing infection pressure from Europe with the anticipated arrival of migratory waterbirds. Since our previous outbreak assessment on 8 October 2025 (High pathogenicity avian influenza (HPAI) in Great Britain and Europe) there have been 9 reports of HPAI H5 clade 2.3.4.4b in domestic poultry in Great Britain (8 in England and 1 in Wales). All 9 reports have been confirmed as HPAI H5N1. Since our previous assessment on 8 October 2025, there have also been 54 more cases of HPAI H5 clade 2.3.4.4b events involving “found-dead” wild birds (number based on laboratory testing date) in Great Britain. The total since the start of the HPAI season on 1 October 2025 is now 62. Of these 62, 60 have been confirmed as HPAI H5N1, 1 as HPAI H5N5 (see our previous assessment) and 1 as HPAI H5Nx (see Map 1 for wild bird cases). The number of wild bird cases (based on laboratory testing date) after falling week on week in September, has increased markedly since the beginning of October increasing over 3-fold in the last week of October. It is notable that most of the cases in found dead wild birds in October are resident wildfowl (Canada geese, greylag geese, mute swans and mallards) mostly inland with just one case in gulls which accounted for half of the wild bird cases over the summer. The wild bird risk level across Great Britain has therefore been elevated to VERY HIGH, noting that there are still more wild migratory waterbirds to enter Great Britain in the coming weeks from Europe where HPAI reports have also increased exponentially in the last few weeks.

🌏 Biodiversity loss has deep-rooted causes—from power imbalances to short-term priorities. These shape indirect & direct drivers like land/sea use change, exploitation & climate change.

Graphic from the IPBES #TransformativeChange Assessment ⤵️
An infographic showing the progression from underlying causes to environmental impacts across terrestrial, freshwater, and marine ecosystems. The diagram flows left to right through three main sections: "UNDERLYING CAUSES" lists three core issues: Disconnection from and domination over nature and people Concentration of power and wealth Prioritization of short-term, individual and material gains "INDIRECT DRIVERS" includes four categories: Demographic and sociocultural Economic and technological Institutions and governance Conflicts and epidemics "DIRECT DRIVERS" shows relative impact percentages across terrestrial, freshwater, and marine environments, represented by horizontal bars with color-coded segments for: Land/sea use change (purple) Direct exploitation (light purple) Climate change (yellow) Pollution (gray) Invasive alien species (orange) Others (light gray) The right side features a circular illustration divided into terrestrial, freshwater, and marine zones with representative wildlife silhouettes.

Avian influenza has been detected at a breeding farm in Ravels, just across the border in Belgium. Belgium has established a restriction zone that partly extends into the Netherlands. Therefore, the Minister of Agriculture, Fisheries, Food Security and Nature (LVVN) has set up a restriction zone around Baarle-Nassau in North Brabant.
