The U.S. Food and Drug Administration is investigating reports of five deaths that may be associated with Monster Beverage Corp.'s energy drink.
The agency acknowledged the adverse reports Monday, but FDA spokeswoman Shelly Burgess says the reports don't prove that the drinks caused the deaths.
This follows news that the parents of Hagerstown, Md. teen Anais Fournier filed a lawsuit in California on Friday against Monster Beverage Corp. for failing to warn about the product's dangers.
The 14-year-old's family says she went into cardiac arrest last December after drinking two 24-ounce cans of Monster Energy Drink in 24 hours.
An autopsy concluded she died of cardiac arrhythmia due to caffeine toxicity. She had an inherited disorder that can weaken blood vessels.
Monster says it doesn't believe its products caused any deaths.
