(NEXSTAR) — While investigators in Costa Rica have walked back a previous suggestion regarding what may have caused the death of Miller Gardner, the 14-year-old son of former New York Yankees outfielder Brett Gardner, they have indicated that “food intoxication” may still be involved. Inves tigators initially believed the teen may have died of asphyxiation, which was possibly a reaction to something he had eaten earlier, ABC News and NBC News reported on Monday. An official speaking with CNN pointed to vomit being found with the boy as a potential determining factor. However, on Tuesday, officials ruled out asphyxiation as the cause of Miller Gardner's death, ABC News and People reported. Costa Rican National Police said the teen's respiratory tract was clear and noted that additional tests were being done. It could take two to three months for those tests to be completed. Investigators have indicated that food intoxication may still be a factor — but what is it? Is last night’s food what made you sick? What you can do next Food intoxication is sometimes referred to as food poisoning. Bacteria in the food you eat can lead to a range of illnesses, the District of Columbia's health office explains. When it comes to food poisoning, the most common symptoms include nausea, vomiting, stomach pains or cramps, fever, and diarrhea, according to the Centers for Disease Control and Prevention. In many cases, bouts of food poisoning are brought on by salmonella or E. coli — bacteria that lead to numerous recalls in the U.S. every year. Those experiencing severe symptoms should seek medical care, the CDC warns. That includes bloody stool, diarrhea that lasts more than a few days, a fever greater than 102 degrees F, vomiting that prevents you from keeping liquids down, and signs of dehydration like a dry mouth and throat, feeling dizzy when standing, and not urinating much. While most will experience mild cases if they have food poisoning, some can develop meningitis, kidney damage, arthritis, brain and nerve damage, and hemolytic uremic syndrome, which can lead to kidney failure, the CDC says.

An autopsy and toxicology report are not expected for some time, according to officials. While his parents previously said "several other family members" had also become sick, they did not provide any information on their conditions. “We have so many questions and so few answers at this point,” the Gardners, who share another son, Hunter, said Sunday. The family has asked for privacy as they “mourn and search for healing.” Brett Gardner of the New York Yankees poses with his family at an event at the MLB Fan Cave in New York City on Thursday, August 8, 2013.

Miller Gardner had been playing football in South Carolina, ESPN reports, and wore No. 11, the same number worn by his father while he played for the Yankees. Miller also played as an outfielder and pitcher on the baseball diamond, according to The Athletic. Gardner last played with the Yankees in 2021.
