The label on the coffin-shaped box dared customers to wait as long as possible before eating or drinking anything after consuming the chip, and then to post their reactions on social media.

This year’s challenge produced many videos showing people begging for water or milk or shoveling ice cream into their mouths after eating the chip.

A spokeswoman for Paqui, Kim Metcalfe, said that the company was “deeply saddened” by Harris’s death and “express our condolences to the family.”

By Thursday, all that remained on the challenge’s website was the company’s new statement, the original warning label and a shortened F.A.Q.

A local CBS affiliate in Boston said on Wednesday that it had found the chip at a grocery store about 10 minutes from Harris’s school.
