He and his 4-year-old sister both ordered apple juice, but as soon as they took a sip, something horrifying occurred.

Their father, Richard Zaragosa Sr. says, ”As soon as they took a sip they were throwing up and there was blood. Any other time that they brought apple juice to us they would bring a Styrofoam cup with ice, and a separate drink so you can open and pour it if you want to. This time they brought it already made.”
