Claim: * Snapple is affiliated with the Ku Klux Klan (or donates money to the anti-abortion group Operation Rescue).

Status: * False.

Origins: * In 1992 a rumor wafted through the air that Snapple, the highly-popular line of ice teas and juice drinks, had ties to the Ku Klux Klan. Another specious whisper intoned that it supported Operation Rescue, a pro-life group. By year-end, a third was making the rounds, that the company brewed some of its teas in then-apartheid South Africa.

"The rumors are so ridiculous we thought they would go away, but they didn't," said Leonard Marsh, then president of the firm. "It reached the point it was getting out of hand and we had to address it."

In 1993 Snapple Beverage Co. went toe to toe with the slanders. Full-page ads appeared in major northern California newspapers, denying the claim that the company was allied with either the Ku Klux Klan or Operation Rescue.

"We are not involved in any way whatsoever with the KKK, Operation Rescue or any other type of pressure group or organization, period," said the ad. The claims about South Africa (a far less widespread rumor and one that only followed months later on the heels of the other two) were not publicly addressed, but they too were false.
