Face to Face With an Alligator? Here’s What to Do

An 11-foot alligator that tipped over a canoe and killed a woman in Central Florida on May 6 served as a reminder that, while alligator attacks on humans are “extremely rare,” as a state wildlife official said, they do happen, sometimes with fatal results.
“This serves as a somber reminder of the powerful wildlife that share our natural spaces,” said Roger Young, the executive director of the Florida Fish and Wildlife Conservation Commission.
Florida had an average of eight unprovoked alligator bites a year over the 10-year period that ended in 2022, according to the commission. Many of them were serious enough to require medical attention.
The commission has been urging people to exercise caution in or near the water during alligator mating season, which runs from early April to June. The risk of an attack is higher, it said, because alligators tend to be more aggressive, active and visible during this time.
The agency and other wildlife commissions offered these tips for avoiding or staying safe around the reptiles, which can grow up to 15 feet long.
Where are they?
Alligators can be found from central Texas eastward to North Carolina, according to the Louisiana Department of Wildlife and Fisheries.
Louisiana and Florida have the largest populations — more than one million each. Georgia has 200,000 to 250,000 alligators and South Carolina is home to about 100,000.
Morgan Hart, the alligator project leader for the South Carolina Department of Natural Resources, believes alligator attacks have increased in the state over the years because of “the sheer growth in human population in the coastal plain of South Carolina.”
When new housing developments are built, artificial lakes are often created with them and then quickly inhabited by alligators.
Be alligator aware.
If you encounter an alligator on land, “you can simply back away from it,” Ms. Hart said.
“Alligators will also hiss if they feel someone is too close and they can’t get away,” she said.
People should be wary of any alligator that approaches, she said, as it may be a sign that it has been fed and associates humans with food.
Humans should also keep at least 30 feet from alligators at all times, according to the Texas Parks and Wildlife Commission.
“They rarely chase people, but they can outrun or outswim the fastest person for the first 30 feet,” the agency said, noting that alligators can sprint up to 35 miles per hour for short distances on land.
Watch your children and dogs closely.
Alligators prefer to pursue prey they can easily overpower.
“Pets often resemble alligators’ natural prey,” said Lauren Claerbout, a spokeswoman for the Florida wildlife commission.
People should keep their pets on a leash and under control, and not allow them to swim or exercise in canals, ponds or lakes that may have alligators.
“The sound of dogs barking and playing may draw an alligator to the area,” the Florida wildlife commission said.
Be careful where you swim.
Wildlife agencies suggest that people swim only in designated areas during daylight hours, and without a pet.
“Alligators are most active between dusk and dawn,” Ms. Claerbout said.
If you encounter an alligator in the water, remain calm and do not approach it, according to the Florida wildlife commission.
Don’t feed them.
It is illegal, and dangerous, to feed alligators in Florida, Georgia, South Carolina and Texas (except during that state’s hunting season).
The Louisiana Department of Wildlife and Fisheries said that people should not throw fish scraps into the water or feed other wildlife in areas where alligators congregate.
“As long as people don’t feed them,” said Donald Houser, the general manager at Gator Park, which is just south of Miami and features shows with alligators. He added that an alligator loses its fear of humans after three days of a person feeding it.
“Just stay away from it, basically,” he said.
How to fight back.
You should fight back against an alligator only if it gets hold of you, officials said.
“In that case, aim for its eyes, nose or throat, which are its most sensitive areas,” according to Everglades National Park in South Florida, adding that people should “hit, kick, or jab with as much strength as you can muster to try and force the gator to release its grip.”
Still, if you are grasped in an alligator’s jaws, there is a slim chance that you would be able to escape, Mr. Houser said.
“You better have someone close that knows what they are doing,” he said.
“Alligators don’t eat people,” he said, but they may bite someone and then spit the person out. By then, it may have held the person under water too long, he said, “and it may be too late.”

Trump administration restores funds for HIV prevention following outcry

The Trump administration has lifted a freeze on federal funds for HIV prevention and surveillance programs, officials said, following an outcry from HIV prevention organizations, health experts and Democrats in Congress.
The Los Angeles County Department of Public Health received notice from the U.S. Centers for Disease Control and Prevention on Thursday that it had been awarded nearly $20 million for HIV prevention for the 12-month period that began June 1 — an increase of $338,019 from the previous year.
“Let’s be clear — the Trump administration’s move to freeze HIV prevention funding was reckless, illegal and put lives at risk,” said Rep. Laura Friedman (D-Glendale) in a statement. “I’m relieved the CDC finally did the right thing — but this never should have happened.”
The CDC didn’t immediately respond to a request for comment.
Friedman and other advocates for HIV prevention funding sent a letter to Health and Human Services Secretary Robert F. Kennedy Jr. last month, warning that proposed cuts to these programs would reverse years of progress combating the disease and cause spikes in new cases — especially in California and among the LGBTQ+ community.
The letter cited estimates from the Foundation for AIDS Research, known as amfAR, suggesting the cuts could lead to 143,000 additional HIV infections nationwide and 127,000 additional deaths from AIDS-related causes within five years.
Los Angeles County, which stood to lose nearly $20 million in annual federal HIV prevention funding, was looking at terminating contracts with 39 providers. Experts said the dissolution of that network could result in as many as 650 new cases per year — pushing the total number of new infections per year in the county to roughly 2,000.
“Public Health is grateful for the support and advocacy from the Board of Supervisors, the Los Angeles County Congressional delegation, and all of our community based providers in pushing CDC to restore this Congressionally approved funding,” a spokeswoman for the county’s health department said.
“Looking forward, it is important to note that the President’s FY26 budget proposes to eliminate this funding entirely, and we urge our federal partners to support this critical lifesaving funding,” she said.

Malaysia will stop accepting U.S. plastic waste, creating a dilemma for California
Malaysia will ban plastic waste imports from the U.S. starting Tuesday because of America’s failure to abide by the Basel Convention treaty on international waste transfers, in a move that could have significant consequences for California.
Malaysia emerged as a major destination for U.S. waste after China banned American waste imports in 2018. California shipped 864 shipping containers, or more than 10 million pounds of plastic waste, to Malaysia in 2024, according to the Basel Action Network, an advocacy group. That was second only to Georgia among U.S. states.
Under Malaysian waste guidelines announced last month, the country will no longer accept plastic waste and hazardous waste from nations that didn’t ratify the Basel Convention, the international treaty designed to reduce the international movement of hazardous and other waste. The U.S. is one of just a handful of countries, including Fiji and Haiti, that hasn’t signed the pact.
Malaysia will continue to accept plastic waste from Basel signatories. However, exports from those countries will be subject to pre-inspection at the nation of origin, according to the new guidelines
Steve Wong, the chief executive of Fukutomi, a Hong Kong-based global plastic recycling company, suggests it is already having an effect on shipping ports.
“With scrap inventories building up at ports and yards, and no clear guidance yet on the enforcement discretion or timeline of Malaysia’s new system, the market for imported plastic waste has effectively frozen,” he wrote in an email to people who follow recycling trends, which was shared with The Times.
Much of California’s plastic waste is sent overseas. A Los Angeles port spokesman said he was unaware of the impending ban. Long Beach port officials didn’t immediately respond to requests for comment.
An Oakland port spokesman said that facility “hasn’t historically seen much volume in this commodity, so we don’t anticipate any impact from this change.”
Workers open the door of plastics waste shipment from Australia before sending back to the country of origin in Port Klang on May 28, 2019. A total of 3,000 metric tonnes of contaminated plastic waste will be shipping back to their countries of origin today, signalling Malaysias effort to take the lead in the global crusade against unscrupulous export of scrap.

According to Wong’s email, the coming ban has already disrupted trash export routes significantly, particularly for the plastics used in grocery bags, trash can liners and food wrap.
“The scrap plastics market in Malaysia has come to a virtual standstill amid tightening import regulations and widespread uncertainty ahead of the new control regime taking effect on 1 July 2025,” Wong wrote in the email. “Recyclers, traders, and suppliers are all reporting minimal or no movement of plastic waste.”
Jim Puckett of the Seattle-based Basel Action Network cheered Malaysia’s decision.
“The ‘recycling’ is doing more harm than good as only a fraction of the exports ever get recycled,” said Puckett, the group’s founder and chief of strategic direction. “The plastics that are not feasible to be recycled are often hazardous, or contain microplastics, which are commonly dumped, burned, or released into waterways. The export of plastic waste for recycling is a complete sham and it is a relief that the U.S. contribution to this plastic waste shell game is increasingly outlawed.”
According to California’s waste agency, CalRecycle, the state exported 11.3 million tons of recyclable materials overseas to places such as Malaysia, Thailand, Vietnam, China, Taiwan, South Korea, Mexico and Canada — in 2022.
That number includes 100 million pounds of scrap plastic. Although the Basel Action Network’s numbers indicate more than 10 million pounds went to Malaysia, CalRecycle’s 2022 report didn’t break down plastic exports to individual nations.
A spokesperson for CalRecycle said that California “is working to reduce plastic pollution in our state and around the world” and that exports of scrap plastic have significantly declined over the last 10 years.
Maria West, the agency’s communications director, said that in 2018, California exported roughly 421,000 tons, or nearly 842 million pounds of plastic scrap to Malaysia. She said that number dropped 98% in 2024 to 8,000 tons, or about 16 million pounds.
Several major waste companies in California, including Athens Services and Recology, didn’t immediately respond to requests for comment.
Critics of California’s waste system say a 1989 state law that requires cities and jurisdictions to divert waste from landfills led to an increase in the export of waste overseas.
Until 2018, China was the major importer of U.S. plastic waste. However, after China implemented it’s National Sword policy — which banned the import of most plastic waste — nations began sending their waste elsewhere, often to less economically advantaged nations such as Malaysia, Vietnam and Thailand.
Although some of the plastic is recycled in these nations, much of it is incinerated or placed in landfills, where it chokes rivers and flows into the ocean.
Waste advocates such as the Basel Action Network and participants in the Basel Convention are working to reduce the international movement of contaminated, nonrecyclable plastic from economically advantaged countries, such as the United States, to less advantaged nations.
Jan Dell, the president of LastBeachCleanUp, a Laguna Beach-based anti-plastic waste organization, praised the Malaysian decision.
“We’re calling on cities, waste companies, brokers, and shipping companies to respect Malaysia’s sovereign law and STOP all plastic waste shipments,” she wrote in an email. The plastic waste must NOT be re-rerouted to other poor countries.”
In 2022, Gov. Gavin Newsom signed Senate Bill 54, a landmark plastic law that is designed to establish a circular economy for single-use plastic products and packaging. The law addresses the export of plastic waste and requires product manufacturers to certify that their products are being recycled or composted in ways that reduce environmental pollution and minimize health effects for people who live near where the product is sent.
CalRecycle is currently working on drafting regulations that will enable the implementation of the law, but West, the agency’s spokeswoman, said the law requires that for any material to be considered recycled, it “must go to responsible end markets, ensuring material actually gets recycled instead of becoming waste in landfills or the environment.”

One in five U.S. food and beverage products is made with synthetic dyes

Odds are, something in your pantry is colored with petroleum.
Synthetic dyes — which give fruit snacks their bright colors and cereals their rainbow crunch — are embedded into the everyday foods that fill grocery store shelves, often in ways consumers don’t realize. However, concern over their health effects has been growing in recent years, fueled by mounting evidence that certain synthetic dyes may harm children’s long-term health.
A new study shows that the use of these chemicals in the manufacturing of foods and beverages in the U.S. is more widespread than many might expect. Nearly 1 in 5 food items and beverages sold in the U.S. contain synthetic dyes, and many of them are commonly marketed to children.
For many Americans, synthetic dyes such as Red 40 and Yellow 5 have become invisible staples of their diet. These petroleum-derived additives are commonly added to processed food and beverages to increase visual appeal and maintain color consistency. However, emerging research has made it clear that they also increase the risk of a range of adverse neurobehavioral effects — to which children are especially susceptible.
A national study published Tuesday in the Journal of the Academy of Nutrition and Dietetics looked at nearly 40,000 products produced by the top 25 U.S. food and beverage manufacturers, and found that synthetic food dyes were present in 19% of them.
The study also determined that products using synthetic dyes were significantly more likely to be high in added sugars and low in nutritional quality. Even more concerning, researchers found that 28% of the products in categories most commonly marketed to children, including breakfast cereals, candy and sugar-sweetened beverages, contained synthetic dyes.
Although the study focuses on the prevalence of synthetic dyes in U.S. food and beverages, Elizabeth Dunford, a lecturer at the University of New South Wales and co-author of the study, noted that its findings reinforce concerns among parents and public health experts about the potential neurological and behavioral effects of these additives.
A 2021 assessment from the California Office of Environmental Health Hazard Assessment concluded that these additives can “cause or exacerbate neurobehavioral problems in children.” Similarly, a 2022 review found that 52% of studies found a significant association between synthetic dye consumption and adverse behavioral outcomes in children, both those with and without existing behavioral disorders.
These health concerns are not limited to behavioral problems. Red 3, for example, has been shown to cause cancer in laboratory rats, and Yellow 5 has been associated with allergic reactions in some individuals. However, despite decades of concern, current U.S. Food and Drug Administration registrations are still based on studies performed 35 to 50 years ago.
In the recent study, the most common dyes that Dunford and her team found were Red 40, Yellow 5, and Blue 1, appearing in 14%, 11%, and 11% of products, respectively. Synthetic dyes were found in such products as blueberry bagels, guacamole, corn chips and hot dog buns — items that consumers might not expect them. “Even as an educated person, I’ve been tricked,” Dunford said. “Consumers can be misled … when there are all these claims on the front of the pack that say ‘healthy’ or ‘made with real fruit juice,’ but it still has dyes.”
The study found that foods and beverages containing synthetic dyes, on average, had 141% more sugar than dye-free products. The correlation between sugar and synthetic dyes was even more pronounced when it came to products marketed to kids: foods and beverages in the five categories most heavily marketed to children had a mean total sugar content of 42.6 grams per 100 grams — 264% higher than comparable products in other categories.
This marketing strategy, which pairs bright colors with high sugar content, may be part of the reason these foods are so appealing to kids.
But Dunford said that in her personal experience, children won’t notice if they’re given replacement options without those additives. When buying snacks for one of her kid’s parties, she opted for a version of a common brand of corn chips with no synthetic dyes or preservatives. “I gave them to kids at a party, and no one said anything.” Dunford said. “This just goes to show that it’s really the marketing that drives the desire for these products and causes the problems.”
Some steps have been taken to remove synthetic dyes from food and beverages. California banned Red 3 from all foods in 2023 and prohibited six other synthetic food dyes in foods sold in schools in 2024. More recently, in January of this year, the FDA announced that Red 3 will be banned nationwide in all food products by 2027. Warning labels are another potential option to limit synthetic dye consumption, and are being used in the European Union to identify foods containing Red 40, Yellow 5, and Yellow 6.
However, the burden still falls largely on consumers to scrutinize ingredient lists and marketing claims. For many families, that means navigating a colorful and oftentimes misleading food landscape, armed with little more than the fine print on the back of a box.
