    How E. Coli in Food Makes People Sick

    The bacteria sickens an estimated 265,000 Americans each year.Last week, federal officials announced recalls of ground beef and organic walnuts because they were potentially contaminated with E. coli bacteria that can make people sick.The recalls involve more than 16,000 pounds of ground beef distributed by Cargill Meat Solutions and sold at Wal-Mart stores in 11 states, as well as organic shelled walnuts sold in bulk in natural food and co-op stores in 19 states. So far, the recalled walnuts have been associated with 12 illnesses, including seven hospitalizations, in Washington State and California.No illnesses have been reported from the ground beef recall, although ground beef remains one of the most common sources of illnesses from these bacteria, which are responsible for an estimated 265,000 illnesses annually. Most of these, however, are not diagnosed or tracked by the Centers for Disease Control and Prevention because people often recover on their own without visiting a doctor, said Matthew Wise, chief of the C.D.C.’s Outbreak Response and Prevention Branch.Here’s what you need to know about E. coli to stay safe.Where You’ll Find the BacteriaThere are many different kinds of E. coli, and most of them are harmless to humans, said microbiologist Edward G. Dudley, director of the E. Coli Reference Center at Pennsylvania State University.Some types do, however, make people sick, he said. Those that most commonly cause illness in humans, known as Shiga toxin-producing E. coli, primarily reside in cow intestines, which is why they often contaminate ground beef. The E. coli implicated in the ongoing walnut and ground beef recalls are a type of Shiga toxin-producing E. coli.Because these bacteria eventually work their way out of animal intestines and into feces, they can also contaminate farm soil, which is why E. coli outbreaks are also often tied to produce, Dr. Dudley explained. They can also contaminate ponds, lakes and rivers.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Brazil’s climate politics are shifting. That matters for the whole planet.

    The Amazon is emerging as a central issue in this year’s presidential campaign. Leaders have taken note.A message from your Climate Forward host: I’d like you to meet Manuela. She’s my partner on Climate Forward, and you’ll hear from her regularly when I’m out on reporting trips and unavailable to write the newsletter. Today, she takes you inside the climate politics of her home country, Brazil. — Somini SenguptaIn Brazil, beef isn’t just food. It’s political. It’s a symbol of dignity and equality, and the price of beef is a kind of barometer of well-being in the country.“Beef is not a privilege for people with money,” former President Luiz Inácio Lula da Silva said in an interview last year.But now, with elections just months away, da Silva, who is better known as Lula, seems to be taking a more environmentally conscious position. He’s suddenly talking about vegetable barbecues and organic salads.“I broadened my perspective,” he said on Twitter in February. He was not just concerned about whether the average Brazilian could afford a barbecue, Lula said, “but also vegetarian people, who don’t eat meat, being able to eat a good organic salad, us encouraging healthier agriculture in our country.”At 76, and with more than five decades of politics under his belt, Lula is adapting. And his willingness to do so makes it clear that, for the first time, climate and the environment will be at the center of the debates before Brazilians vote for president and the national legislature on Oct. 2.Lula, who led Brazil from 2003 to 2010, is one of the best-known politicians in the developing world. Under his administration, millions rose out of poverty, helped by China’s growing hunger for Brazilian commodities like soybeans and steel.Beef was, in some ways, a thread that ran though his presidency. It became a more frequent part of daily meals and one of the country’s major exports. Lula’s administration poured millions from Brazil’s development bank into meatpacking companies, and those operations, in turn, eventually grew to become major drivers of deforestation in the Amazon.This time around, though, Lula is talking about supporting that “healthier agriculture” he mentioned on Twitter.Izabella Teixeira, who served as one of Lula’s environment ministers, told me the former president always treated climate issues seriously. But she said she saw something new in the way climate and environment issues seem to be gaining prominence in his speeches and debates.“He is looking at it with a modern mind set,” she said. “It is one thing to correct the past, to undo mistakes. It is another thing to affirm new paths.”President Biden similarly made climate a pillar of his campaign, as did Gabriel Boric, who became president of Chile in March. Just a few weeks ago, Colombia’s leftist presidential candidate Gustavo Petro chose an environmental activist as his running mate. The first round of that election is May 29.The choice Brazilians make matters for global climate targets. Brazil is, by some measures, the world’s sixth-biggest emitter of greenhouse gases. More important, though, is why: It is currently slashing its part of the Amazon, the world’s largest rainforest, at a pace not seen in over a decade.Lula’s environmental record is mixed. Back in the day, his administration pushed for new policies that sharply curbed Amazon deforestation, even as agribusiness, including beef, grew. But he seemed to disregard the need for an energy transition, instead refusing to support legislation that would have required Brazil to phase out fossil fuels.Under the current president, Jair Bolsonaro, climate action has been all but abandoned. The recent explosion in deforestation rates, which have angered the world, will unquestionably be one of the main legacies of his presidency.Brazil’s current policies have intensified its climate challenge. And it’s not just because of beef. Soy, the country’s top commodity, is increasing pressure on the Cerrado, the country’s vast tropical savanna. There’s also Brazil’s heavy dependence on oil and steel exports.Bolsonaro’s rise to power is widely seen as a response to a multibillion dollar corruption scandal that upended Brazilian politics years ago. Prosecutors said Lula was implicated at the top of the scandal. He spent 580 days in prison in connection with a conviction that was ultimately overturned.As Lula has clawed his way back into public life, he has refused to acknowledge mistakes in the corruption scandal. When it comes to climate policy, though, he has signaled a willingness to reform his legacy.Earlier this week, speaking to thousands of Indigenous people gathered in a demonstration in Brasília, the capital, he promised to appoint an Indigenous cabinet minister. It would be a first for Brazil, a country where Indigenous people are at the forefront of the environmental movement.Past governments of his Workers’ Party, Lula said, “didn’t do all they should have done” for Indigenous people.So far, Lula has the lead over Bolsonaro, who is seeking re-election, in all the main opinion polls, though the race has been tightening. Hunger, unemployment, inflation and the Covid pandemic will also be major issues during the campaign.But the two candidates’ radically different views on the environment could be crucial. According to a poll in September, 80 percent of voters believe protecting the Amazon rainforest should be a priority for presidential candidates.A majority also said a specific plan to defend the Amazon would increase their willingness to vote for a candidate.California’s plan to eliminate gas cars, if adopted, would very likely set the bar for the broader auto industry.Justin Sullivan/Getty ImagesEssential news from The TimesPhasing out gas cars: Officials in California made public plans to prohibit the sale of new gasoline-powered cars by 2035.White House departure: People close to Gina McCarthy, President Biden’s top climate adviser, say she plans to quit because she is unhappy with the slow pace of progress.Even cactuses aren’t safe: More than half of species could face greater extinction risk by midcentury, a new study found, as rising heat and dryness test the plants’ limits.Antarctic puzzle solved: Researchers say the collapse of the two ice shelves was most likely triggered by vast plumes of warm air from the Pacific.‘Silent victim’ of war: Research on past conflicts suggests that, in addition to the human toll, the Russian invasion of Ukraine could have a profound environmental impact.From the Opinion sectionDitch the gas-powered leaf blower: Get an electric one or just use a rake, Jessica Stolzberg writes.Other stuff we’re followingThe latest issue of National Geographic is all about saving forests.A new analysis showed that many big utilities in America are actively pushing back against climate policies, according to The Washington Post.Banks around the world are abandoning coal projects, except in China, according to Bloomberg.A new podcast from the Food & Environment Reporting Network talks to farmers about what they are doing to adapt to climate change.Parts of the Sacramento Valley in California have received their earliest-ever “red flag” warning for fire danger, Capital Public Radio reported.One TikToker found the transportation of the future.Adélie penguins on an iceberg near Paulet Island at the tip of the Antarctic Peninsula. Tomás MunitaBefore you go: For these birds, location mattersAdélie penguins are having a rough time on the western side of the Antarctic Peninsula, where warming linked to climate change has occurred faster than almost anywhere else on the planet. One researcher called the situation a “train wreck” for the birds. On the eastern side of the peninsula, however, it’s a very different story. Adélie populations there seem to be doing just fine. You can find out why, and see some impressive photos from a recent survey expedition in our article.Thanks for reading.
