Brazil, the world’s biggest chicken exporter, has found Newcastle disease on a turkey farm, and the first market reaction has already hit the stock of one of its largest meat groups. MBRF shares fell about 4% on Monday as investors weighed a possible pause in poultry sales to China.
For US readers, the case matters because a Brazilian export pause can move global poultry prices and shift trade toward other suppliers, including American exporters. Our Brazil news page follows the story as China decides.
Outbreak Confirmed in Santa Catarina
Brazil’s Agriculture Ministry (MAPA) found the virus during an epidemiological investigation by Santa Catarina’s official veterinary service at a commercial turkey farm in Nova Itaberaba, in the west of the state. Samples were collected on 21 September, and a federal laboratory in São Paulo confirmed the virus on Sunday 18 October.
The farm held about 6,000 birds and is under official quarantine, with eradication and disinfection ordered. The ministry said it is covering about 133 farms and establishments in the area.
Agriculture Minister André de Paula said at a press conference in Brasília on Monday that Brazil had started official communication with the World Organisation for Animal Health and trading partners. The ministry also said that inspected poultry products already on the market remain safe to eat.

How the China Suspension Works
Under a sanitary understanding with China, Brazil suspends exports when Newcastle disease is found, so that Beijing can decide how far any restriction should reach, said Ricardo Santin, president of the Brazilian Animal Protein Association (ABPA). Beijing can then limit the measure to the affected area or the state, or widen it.
Brazilian reports on Monday differed on timing: some said the China-bound suspension had begun, while others said the formal notice was still being prepared. The ministry had not published the final scope when this article was written.
China took about 10% of Brazil’s chicken exports from January to September 2026, around 420,000 tonnes, according to ABPA figures. Brazil shipped about 4.4 million tonnes of chicken in total over the same nine months, ABPA data show.
Shares Fall on Export Fears
MBRF was the biggest decliner on Brazil’s main stock index on Monday, falling about 4.1% to 4.4% depending on the data provider. It closed near R$18.20 (about US$3.60, at 5.03 reais per dollar, EODHD).
JBS, a larger Brazilian meat group that also trades in New York, fell as well, by roughly 1% to 2% depending on the listing. The size of any hit to MBRF’s earnings is not known.
A pause limited to Santa Catarina would hurt less than a national ban, because exporters can ship from plants in other states. That is why the market is watching China’s decision on scope more closely than the outbreak itself.
What the 2024 Case Shows
In July 2024 a Newcastle case at a farm in Anta Gorda, Rio Grande do Sul, led China to suspend chicken imports from Brazil. China lifted the national suspension on 12 August 2024, about a month later.
Plants in Rio Grande do Sul stayed barred until January 2026, so regional restrictions can last far longer than national ones. Industry voices expect a similar pattern now, but that is an expectation and not an announced timetable.
Our earlier report on Brazil’s record chicken exports showed how large China is as a buyer. The 2024 precedent is the best guide to what comes next.
What It Means for You
For a US investor, the story is a reminder that animal-disease news can move emerging-market meat stocks within hours, even when the outbreak is small. JBS, listed in New York, is the closest US-traded name.
For US poultry exporters and buyers, a longer Brazilian pause would tighten global supply and could lift prices at the margin. A quick resumption of shipments would leave the market where it was last week.
What Is Not Known
It is not known whether China will restrict only Santa Catarina or all of Brazil, or how long any restriction will last. The ministry has not said whether further cases have been found around the farm.
MBRF’s exposure to China and the earnings effect have not been quantified by the company. The source of the virus is still under investigation.

Frequently Asked Questions
What is Newcastle disease?
Newcastle disease is a contagious viral illness of birds that can kill poultry and block trade. It is a different disease from avian flu, but trading partners such as China treat both as grounds to restrict imports.
Why do MBRF shares fall on this news?
Investors fear that China will pause poultry imports from Brazil, which would cut export revenue for companies such as MBRF. The shares fell about 4% on Monday 19 October 2026.
How much chicken does China buy from Brazil?
China took about 10% of Brazil’s chicken exports from January to September 2026, around 420,000 tonnes. Brazil exported about 4.4 million tonnes in total over the period, according to ABPA.
Is Brazilian chicken safe to eat?
The Agriculture Ministry said that inspected poultry products already on the market are safe to eat. Newcastle disease is a bird illness and the ministry reported no consumption restriction.
