The United States reported the first outbreak of the deadly H7N9 bird flu on a poultry farm since 2017, as the country continues to grapple with another bird flu strain that has infected humans and caused egg prices to hit record highs.

The spread of avian influenza, commonly called bird flu, has ravaged flocks around the world, disrupting supply and fuelling higher food prices. Its spread to mammals, including dairy cows in the US, has raised concerns among governments about a risk of a new pandemic.

The strain that has caused most damage to poultry in recent years and the death of one person in the US is the H5N1.

But the H7N9 bird flu virus has proved to have a far higher death rate, killing nearly 40% of the humans infected since it was first detected in 2013, the World Health Organisation said, Reuters reported.

The latest outbreak of H7N9 was detected on a farm of 47,654 commercial broiler breeder chickens in Noxubee, Mississippi, the Paris-based World Animal Health Organisation said in a report on Monday, citing US Authorities.

"Highly pathogenic avian influenza (HPAI) H7N9 of North American wild bird lineage was detected in a commercial broiler breeder chicken flock in Mississippi. Depopulation of the affected flock is in progress," the report says.

"The USDA (Animal and Plant Health Inspection Service (APHIS), in conjunction with State Animal Health and Wildlife Officials, are conducting a comprehensive epidemiological investigation and enhanced surveillance in response to the detection," it added.

Iraq’s buffalo population has more than halved in a decade as the country's two main rivers, the Tigris and Euphrates, suffer severe droughts that endanger the livelihood of many farmers and breeders.
"People have left ... We are a small number of houses remaining," said farmer Sabah Ismail, 38, who rears buffalo in the southern province of Dhi Qar.
"The situation is difficult ... I had 120 to 130 buffalo; now I only have 50 to 60. Some died, and we sold some because of the drought," said Ismail while tending his herd.
Buffalo have been farmed for centuries in Iraq for their milk, and are mentioned in ancient Sumerian inscriptions from the region.
According to Iraqi marshland experts, the root causes of the water crisis driving farmers out of the countryside are climate change, upstream damming in Türkiye and Iran, outdated domestic irrigation techniques and a lack of long-term management plans.
The country has also endured decades of warfare.
Located within the cultivable lands known as the Fertile Crescent that have been farmed for millennia, the Iraqi landscape has suffered from upstream damming of the Tigris and Euphrates and lower rainfall, threatening the lifestyle of farmers like Ismail and leading many to move to the cities.
Iraqi marshland expert Jassim al-Assadi told Reuters that the number of buffalo in Iraq had fallen since 2015 from 150,000 to fewer than 65,000.
The decline is "mostly due to natural reasons: the lack of needed green pastures, pollution, illness ... and also farmers refraining from farming buffalos due to scarcity of income," al-Assadi said.
A drastic decline in crop production and a rise in fodder prices have also left farmers struggling to feed their animals.
The difficulty of maintaining a livelihood in Iraq's drought-stricken rural areas has contributed to growing migration towards the country's already-choked urban centers.
"This coming summer, God only knows, the mortality rate may reach half," said Abdul Hussain Sbaih, 39, an Iraqi buffalo breeder.
