SAO PAULO (Reuters) -Brazil is ready to declare the country free of the bird flu virus on commercial flocks, Edivilson Brum, the head of Rio Grande do Sul state's agriculture department, said on Wednesday in a statement.
The 28-day countdown for reclaiming the country's disease-free status began on May 22 following the complete disinfection of the farm where Brazil's only commercial flock outbreak was detected last month.
Under existing trade protocols, China and other importers banned chicken imports from Brazil, the world's largest exporter, pending measures to control the disease on commercial facilities.
"We have fulfilled all the steps provided for in the health protocols so that Brazil can once again declare itself an influenza-free country to the World Organization for Animal Health," Brum said, referring to the highly pathogenic avian influenza virus (HPAI).
The Brazilian ministry of agriculture did not have an immediate comment.
Brazil's first outbreak hit a chicken breeder farm in Brazil's southernmost state of Rio Grande do Sul last month, triggering trade bans that may now be reversed with the regaining of the disease-free status.
Reclaiming Brazil's status as free HPAI is not automatic and must be confirmed by the World Organization for Animal Health (WOAH), according to guidelines from the body.

Scorpion Venom Could Help Treat Breast Cancer

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A venomous creature from the Amazon rainforest may hold the key to fighting one of the deadliest cancers affecting women today. According to the American Cancer Society, skin cancers aside, breast cancer is the most common cancer among women in the U.S.—accounting for about 30% of all new female cancer cases annually, with an estimated 42,170 women expected to die from it in 2025. Brazilian scientists have discovered that the venom of the Brotheas amazonicus scorpion contains a molecule that kills breast cancer cells in a way similar to chemotherapy, according to a groundbreaking study by researchers in Brazil. "Through bioprospecting, we were able to identify a molecule in the species of this Amazonian scorpion that is similar to that found in the venoms of other scorpions and that acts against breast cancer cells," said Eliane Candiani Arantes, a professor at the University of São Paulo and the project's coordinator.

Sinhyu/iStock/Getty Images Plus The molecule in question, called BamazScplp1, is a type of peptide—a short chain of amino acids—that showed cancer-fighting properties when tested in the lab. It worka similarly to paclitaxel, a standard chemotherapy drug, by inducing necrosis, or uncontrolled cell death, in breast cancer cells. Unlike some other cell-killing processes that are regulated by the body, necrosis causes the cancer cells to burst and die—a tactic that has also been observed in other venom-based compounds. What Is Bioprospecting? Bioprospecting is the process of searching for useful compounds in nature, especially from plants, animals, and microorganisms. In this case, the team explored scorpion venom for potential bioactive molecules—substances that affect living tissues in a beneficial way, such as fighting infections or cancer. Turning Venom into Medicine—Without the Scorpions The researchers aren't milking scorpions for their venom at scale. Instead, they are using a process called heterologous expression, which means inserting the gene that produces a particular protein into another organism—often yeast or bacteria—so it can be produced in large quantities in the lab. "We also intend to obtain these molecules through heterologous expression," Arantes said, referring to BamazScplp1 and other promising compounds. One such host organism is Pichia pastoris, a species of yeast originally isolated in France in 1950. It's commonly used in biotechnology to manufacture proteins that would otherwise be difficult to source naturally. "Our idea now is to obtain this serine protease through heterologous expression [in a fragment or complete gene from a host organism that doesn't have it naturally] in Pichia pastoris," she added. The "Super Glue" Made from Snake Venom This isn't the first time researchers in Brazil have turned to venom for medical innovation. At the Center for the Study of Venoms and Venomous Animals (CEVAP), scientists developed a patented product called fibrin sealant—a kind of biological glue made by combining serinoproteinase (an enzyme found in snake venom) with cryoprecipitate, a component derived from the blood of buffalo, cattle, or sheep and is rich in fibrinogen, a protein essential for blood clotting. When mixed, the two form a fibrin network, mimicking the body's natural healing process. This sealant has been studied for uses like nerve repair, bone injury treatment and even helping restore movement after spinal cord injuries. It is currently in phase three clinical trials, the last stage before a drug can be considered for approval and widespread use. "This growth factor favors the formation of new vessels. If we combine it with colinein-1, we can create an improved fibrin sealant compared to the one being developed at CEVAP, with the possibility of expanding the industrial scale, since it can be obtained through heterologous expression," Arantes said. A Bigger Push Toward Biopharmaceutical Innovation All of this work is being carried out as part of the Center for Translational Science and Development of Biopharmaceuticals (CTS), a program aimed at turning biological discoveries into practical medical treatments. The CTS is part of a broader push by FAPESP, a public foundation in Brazil that funds scientific research. Their strategy isn't limited to scorpion venom. The team has also worked with rattlesnake proteins, including a compound called cholinein-1, and is developing another bioactive substance known as CdtVEGF, which promotes the growth of blood vessels—a potentially valuable tool in tissue regeneration. What Comes Next? The discovery of BamazScplp1 is still in the early stages. The results were shared at FAPESP Week France, a scientific conference held from June 10 to 12 in Toulouse, southern France. But the findings highlight the growing interest in nature-based compounds and how they might work alongside or even replace traditional treatments like chemotherapy. If further tests confirm its effectiveness and safety, the molecule from the scorpion could someday be developed into a new kind of anti-cancer drug, offering patients more options and possibly fewer side effects.

RFK Jr weighs review of vaccines citing aluminum use, Bloomberg News reports

(Reuters) -U.S. Health Secretary Robert F. Kennedy Jr. is considering asking a key government vaccine advisory panel to examine vaccines that contain aluminum ingredients, Bloomberg News reported on Wednesday, citing a source familiar with the matter. Aluminum-containing adjuvants are ingredients that have been used in vaccines since the 1930s, according to the U.S. Centers for Disease Control and Prevention. An adjuvant, used in some vaccines, helps create a stronger immune response in people receiving the shot. Aluminum salts are used in the pneumococcal conjugate vaccine such as Pfizer'sPrevnar, HPV vaccines such as Merck's Gardasil and hepatitis B vaccines. In all cases, adjuvant-containing vaccines are tested for safety and effectiveness in clinical trials before they are licensed for use in the U.S. and once approved, the vaccines are monitored by the CDC and the FDA, according to the CDC. The discussions on reviewing such vaccines could evolve, Bloomberg reported, citing a source who was not authorized to speak publicly on the deliberations. Kennedy earlier in June fired all 17 members of a CDC panel of vaccine experts, drawing protest from many vaccine scientists. The Department of Health and Human Services did not immediately respond to Reuters' request for comment.

How Recall of 20 Million Eggs Could Affect US Prices

The recent salmonella-linked recall of 1.7 million dozen (20.4 million) eggs could drive prices significantly higher, according to one expert. "This is not good news," North Carolina State University economist Mike Walden told Newsweek. "Lower egg supply will increase egg prices." Walden estimated that the recall could see prices rise by 25 percent across the affected regions. The price of eggs, already seen by many as a barometer of inflation, has become a political flashpoint this year. President Donald Trump blamed the increase on Joe Biden's policies before taking credit for the more recent price plunge. Widespread outbreaks of avian flu took a significant toll on production, leading to nationwide shortages and pushing prices up to record highs. While far more contained, the latest recall, prompted by fears over salmonella contamination and impacting nine states, could offset some of the declines in cost that have been seen since March. On June 6, August Egg Company announced a voluntary recall of the brown cage-free and certified organic brown eggs over fears of salmonella contamination. According to the U.S. Food and Drug Administration (FDA), the eggs were sold by multiple brands, including Walmart, between February and May across nine states: Arizona, California, Illinois, Indiana, Nebraska, Nevada, New Mexico, Washington and Wyoming. The Centers for Disease Control and Prevention (CDC) said the eggs could be tied to the salmonella outbreak that has infected 79 people so far this year, and that FDA inspections at the August Egg Company found that samples of salmonella found in the eggs were "closely related" to those seen in the human cases. "The true number of sick people in this outbreak was likely much higher than the number reported," the CDC said, "and this outbreak may not have been limited to the states with known illnesses." Joseph Balagtas, professor of agricultural economics at Purdue University, told Newsweek that the impact of the recall on prices would likely be limited, given the 20.4 million affected eggs represent "tiny fraction" of the more than 8 billion produced each month. For context, he said that the price spikes earlier this year were a result of an egg production shortfall of about 1 billion because of outbreaks of highly pathogenic avian influenza (HPAI) in February. He added that any noticeable upward pressure on prices would likely be masked by the recent decline in the cost of eggs in the U.S. According to the Consumer Price Index reading released by the Bureau of Labor Statistics last week, egg prices dropped 2.7 percent in May, following a 12.7 percent decline in April. However, prices are still up 41.5 percent from the same time last year. August Egg Company, in its recall announcement: "It is important to know that when our processing plant identified this concern, we immediately began diverting all eggs from the plant to an egg-breaking facility, which pasteurizes the eggs and kills any pathogens. "August Egg Company's internal food safety team also is conducting its own stringent review to identify what measures can be established to prevent this situation from recurring. We are committed to addressing this matter fully and to implementing all necessary corrective actions to ensure this does not happen again." Joseph Balagtas, professor of agricultural economics at Purdue University, told Newsweek: "By removing eggs from the market, the recall will put some upward pressure on prices. But I expect the magnitude of the price effect to be small, perhaps imperceptible in the context of day-to-day fluctuations in prices." August Egg Company said that it has stopped selling fresh shell eggs for the time being and urged consumers to return those with the plant code numbers listed in its recall to the place they were purchased for a full refund. The plant code numbers for the recalled eggs can be found printed on the package and are P-6562 or CA5330 with Julian Dates from 32 to 126, the FDA said. The Julian Dates are codes of three to seven digits and represent the date that the food was packaged or manufactured.
