Lethal mushrooms picked in the California wilderness poisoned 14 people late last year, with three requiring liver transplants, including an 18-month-old girl. The cas were reported to the California Poison Control System over a two-week period in December, although the Centers for Dia Control and Prevention (CDC) didn't announce the incidents until Friday.
The mushroom was known as "the death cap" or Amanita phalloides, a fungus responsible for more than 90% of the world's mushroom-related deaths. The CDC said they po "rious public health concerns" and urge the people who want to find food in the forest to have an expert inspect their harvest before eating.
The death cap contains a toxic agent and as few as one mushroom can carry a fatal dosage. In many of the incidents in California, patients reported eating multiple mushrooms. In 2016, the state noticed a wild mushroom poisonings as well as an abundance of wild mu
shroom growth brought on by rain and very warm temperatures.
The cas involved patients picking the mushrooms for themlves while others received the mushrooms from another person. It typically took veral hours for the patients to develop the health problems beginning with the ache in the stomach.
Tho affected ranged in age from 18 months to 93 years old. A 37-year-old man picked and ate one mushroom in Santa Rosa, north of San Francisco, and felt symptoms 10 hours later. A group of five people all got sick, including the 18-month-old girl, after all ate wild mushrooms picked by a stranger in the mountains.
Eleven of the patients recovered and three required liver transplants. In 2012, four people died at a Northern California hospital after all ate a soup made from poisonous mushrooms. The CDC asks people to be careful when picking and eating mushrooms. Before eating, mushrooms should first be examined, identified and reviewed by a mycologist, someone who studies fungi.

Many kids would likely argue that their lunch periods are too short. While the precious breaks from class work are ud to relax and chat with friends, students also need to sca
rf down a full meal to fuel them through the rest of the day.
But it is found that students need more than few minutes to consume tho much-needed nutrients. Longer lunch periods relate with students eating healthier lunches, rearchers found. The study compared food choices with the amount of time students are given to eat. Students with less than 20 minutes for lunch ate less—including nutritional fruits and veggies.
Nationwide, the average lunch period is about 30 minutes, according to a 2014 report from the School Nutrition Association. But rearchers found that the amount of time available to eat can get cut down to less than 10 minutes due to long lunch lines.

Students with less than 20 minutes to eat their lunches consumed 13 percent less of their entrées, 12 percent less of their vegetables, and 10 percent less of their milk compared to students who had at least 25 minutes for lunch.
