Newcastle disease at MBRF-linked supplier hits stocks and clouds export outlook

Published Oct 19, 2026
Share:
Summary:
  • On Monday, people familiar with the situation said a case of Newcastle disease was found at a turkey supplier that raises birds exclusively for MBRF Global Foods SA.
  • Brazil's Agriculture Ministry verified the pathogen in a commercial turkey facility located in Nova Itaberaba, Santa Catarina, adding that the site was shut and all bird movements halted.
  • Meatpacker shares slipped on the headline, with MBRF down 4.1% in Sao Paulo and JBS NV off 1% in New York.

What happened

People with knowledge of the matter said the infection appeared at a turkey supplier serving only MBRF Global Foods SA, feeding its Chapecó plant that produces poultry aimed at export markets. The disease is Newcastle, a viral illness that affects birds' breathing, nerves and digestion.

Brazil's Agriculture Ministry confirmed the highly contagious virus at a commercial turkey operation in Nova Itaberaba in Santa Catarina. Authorities shut the site and halted any movement of birds there. The company did not comment, saying, "as this is an industry-wide matter, we are redirecting inquiries on the subject to the Brazilian Animal Protein Association (ABPA)."

Market and trade reactions

The announcement lands as Brazil works to restart exports to the European Union after updating rules on livestock drug use. Past outbreaks have triggered purchase limits by importing countries, and the hit this time will depend on buyer decisions that could apply to all of Brazil or just certain regions. If key customers curb orders, meatpackers could reroute volumes to other markets.

In a prior Newcastle flare-up in 2024, Brazil halted shipments to China and the European Union. Shares moved lower on Monday's news, with JBS NV down 1% in New York and MBRF falling 4.1% in Sao Paulo.

Containment and messaging

Health inspectors plan to oversee about 133 properties within the municipality of Nova Itaberaba and across three adjacent towns as part of the containment effort. The Agriculture Ministry stated it will keep open lines of communication with international health bodies.

ABPA and Santa Catarina groups ACAV and Sindicarne said there are no risks from consuming the product. They added, "Brazil has a well-established animal health system, with protocols for surveillance, prevention and response to outbreaks of this nature, including containment and disease-control measures established under current regulations."

Common Investing Mistakes: Why a Stock Grade Is One Tool, Not the Whole Toolkit
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.

  • Research works best as one input in a process you own. The grade shows how a stock stacks up. You supply the goal, the timeline, and the rules for being wrong.
