Egg prices in the U.S. dropped 11% in May, reaching their lowest point since December
This comes as consumer demand remained weak following a period of record highs caused by bird flu outbreaks. According to the U.S. Bureau of Labor Statistics, the average retail price for a dozen grade A large eggs fell to $4.548, marking the second consecutive monthly decline. Prices have now dropped about 27% from their March peak, though they remain nearly twice as high as they were a year ago.
Grocers have cautiously reduced egg prices, but demand continues to lag behind seasonal norms. USDA reports that egg consumption typically dips in summer as consumers opt for grilling meats over eggs. Meanwhile, supply concerns persist due to ongoing bird flu outbreaks, with Arizona alone reporting more than 5.5 million birds affected in commercial flocks since late May. Despite these supply risks, subdued demand has been the dominant force driving prices lower.
Brazil faces mixed global response to bird flu case
Mexico eases chicken ban, while Mauritania and Oman tighten restrictions
Brazil’s Agriculture Ministry announced Tuesday that Mexico has scaled back its ban on Brazilian chicken imports, limiting restrictions only to poultry products originating from the southern state of Rio Grande do Sul. The move marks a partial reversal of Mexico’s earlier decision to suspend chicken imports from all of Brazil in response to avian influenza concerns.
At the same time, however, other countries are tightening their import controls. Mauritania has imposed a blanket ban on all Brazilian chicken, while Oman has chosen a more targeted approach, suspending only imports from Rio Grande do Sul.
The restrictions stem from Brazil’s confirmation last month of a bird flu case on a commercial farm in Rio Grande do Sul, prompting a wave of trade barriers from multiple countries.
Brazil is one of the world’s top poultry exporters, and the Agriculture Ministry is actively working to reassure trade partners. Still, the diverging international responses underscore the sensitivity of global meat trade to animal health outbreaks and the potential economic ripple effects.
US beef trade in April shows surge in imports, export struggles
Tariff talks, border shifts, and price pressures reshape global beef flow
U.S. beef trade in April 2025 reflected intensifying shifts in the global market, with imports surging and exports continuing to lag — trends that mirror the impact of ongoing tariff negotiations and domestic supply constraints.
According to Josh Maples of Mississippi State University Extension, “The latest beef trade numbers from USDA show a continuation of larger imports and softer exports than during 2024.” This April marked the first full month reflecting market responses to active U.S. tariff talks, with notable disruptions to both exports and live animal flows.
Export Weakness Led by China Collapse
Total beef exports for April reached 237 million pounds, down 7% from March and 9% lower than April 2024. Year-to-date, exports are trailing 2024 levels by 4%. The most dramatic shift came from China, where beef exports collapsed 68% year-over-year. While exports to Hong Kong helped cushion the blow, combined shipments to the region still dropped by 50%. In contrast, South Korea remained the top buyer, showing year-over-year growth, and Japan posted modest gains.
Import Growth Driven by Brazil, Australia
April beef imports totaled 475 million pounds, down 5% from March but a staggering 45% increase from April 2024. For the first four months of 2025, imports are up 28% year-to-date. Brazil led the surge with shipments up more than 300% from last year, followed by significant increases from Australia, Uruguay, and New Zealand. Imports from Canada fell 14%, and Mexico declined by 1%.
Live Cattle Imports Plummet as Border Tightens
Live cattle imports from Mexico dropped sharply amid growing animal health restrictions. Although some cattle crossed the southern border in April under tight controls, only 88,000 head were imported — down 59% from a year ago. Cumulative imports from Mexico for January through April totaled 192,000 head, compared to 479,000 during the same period in 2024.
“The international trade complex for beef is dynamic and responds to shifts in relative prices,” Maples emphasized, adding that tight U.S. beef supplies, strong domestic prices, and ongoing tariff discussions are key drivers reshaping the flow of beef in and out of the country.
China extends by six months its probe into EU pork imports
Beijing ties case to EV tariff talks with Brussels as tensions simmer
China announced Tuesday that it will extend its anti-dumping investigation into pork imports from the European Union by an additional six months, pushing the probe’s conclusion to Dec. 16, 2025. The Chinese Ministry of Commerce cited the “complexity” of the case as justification for the delay.
While officially framed as a routine procedural extension, the move is widely seen as retaliation for EU tariffs on Chinese electric vehicles (EVs) imposed in 2024. Analysts note that the extension comes at a critical juncture in ongoing negotiations between the EU and China, which are working toward a broader trade arrangement over EV duties. Brussels had argued that Chinese EVs were benefiting from unfair state subsidies, prompting the tariffs.
The original pork investigation — launched in response to an industry complaint — was interpreted as a targeted measure aimed at European agricultural exporters, particularly Spain, Denmark, and the Netherlands, which are among the largest suppliers of pork to China.
Trade watchers now see the pork case as a bargaining chip. “This is tit-for-tat diplomacy with ag and autos at the center,” said one Beijing-based trade policy analyst. Talks are reportedly progressing, but no final deal has been announced.
The extension underscores the high-stakes nature of the trade standoff, with billions of euros in exports on the line for both sides.
Supreme Court Holds Off on Prop 12 Cert Decision — Still Weighing Major Pork Industry Challenge
Justices discuss Iowa Pork Producers' discrimination claims at June 5 conference; no ruling yet on second review of California’s animal welfare law
The U.S. Supreme Court considered whether to hear a new challenge to California’s Proposition 12 during its June 5 private conference, but as of Monday morning, June 9, no decision has been made public. The case, Iowa Pork Producers Association v. Bonta, raises fresh constitutional concerns about whether California’s rules on animal confinement unlawfully discriminate against out-of-state pork producers.
The high court has now relisted the petition multiple times — on May 15, May 22, and again for discussion at the June 5 conference. This suggests continued interest among the justices, but not yet consensus on how — or whether — to proceed.
A New Theory: Discrimination by Design
The Iowa Pork Producers Association (IPPA) claims California’s Prop 12 gives in-state farmers an unfair economic edge by:
— Providing free certification audits through the California Department of Food and Agriculture, while forcing out-of-state producers to hire private, paid auditors;
— Giving California producers six years to comply under an earlier state law (Prop 2), while imposing a much shorter transition period on out-of-state producers.
IPPA argues this creates intentional economic discrimination, violating the Constitution’s Dormant Commerce Clause. This line of attack was not raised in the previous Prop 12 case the Supreme Court considered in 2023.
Dormant Commerce Clause and Pike Balancing in Focus
The case also seeks clarification on how to interpret fractured Supreme Court rulings. In the 2023 National Pork Producers Council v. Ross decision, the Court upheld Prop 12 in a splintered 5–4 ruling, but without a clear majority rationale. IPPA now argues that under the Marks v. United States standard, the Court’s Pike v. Bruce Church balancing framework — used to evaluate burdens on interstate commerce — should govern.
They claim the Ninth Circuit misapplied that precedent when it dismissed their suit and avoided Pike balancing altogether. Several states and industry groups have filed amicus briefs supporting review, warning of rising interstate regulatory conflicts if Prop 12 stands.
June 5: A Conference with No Answer — Yet
The June 5 Supreme Court conference came and went without a definitive ruling on the Prop 12 case. It’s possible the justices are still debating how to proceed — whether to grant full review, issue a summary ruling, or decline the case entirely.
Supreme Court watchers note that repeated relistings often indicate serious internal deliberations. The Court may be considering how far states can go in regulating the production methods of goods sold across state lines, a question with growing relevance as more states pursue state-specific climate, food, or animal welfare mandates.
Missouri probes false report about screwworm
Missouri authorities are investigating a fake press release about New World screwworm, the state’s agriculture department said on Friday. On May 27, a false press release was sent to a northwest Missouri radio station about screwworm, the Missouri Department of Agriculture said. A report on the radio station’s website pressured cattle futures before being taken offline. State officials want to determine “if this was an act with malicious intent to cause panic in agricultural markets,” the department added.
China’s May meat imports unchanged from April, down from year-ago
China imported 513,000 MT of meat in May, unchanged from the previous month but down 7.9% from last year. Through the first five months of the year, China imported 2.67 MMT of meat, down 3.9% from the same period last year.
Brazil’s May poultry exports clipped by HPAI outbreak
Brazil’s poultry exports fell 12.9% to $655 million, while volumes declined 14.4% to 363,100 MT. Trade restrictions following a highly pathogenic avian influenza (HPAI) case in mid-May weighed on exports.
