Viewers react to 60 Minutes "Agromafia" story

What's the point of reporting on the Mafia's phony olive oil scheme if you're not going to reveal the brands involved, one viewer asked on Twitter

On Sunday's 60 Minutes, Bill Whitaker reported the Italian mob has been tampering with extra virgin olive oil:

Some viewers posted an "all-pots" bulletin:

CALLING ALL COOKS.......CHECK THIS OUT!!!!!!!

Others thought twice about their own pantries:

It's not just olives being pressed. Celebrity chef and restaurateur Mario Batali says, since the 60 Minutes story aired, he's being pressed too -- by his patrons:

But many viewers panned the story. A flood of comments appeared on social media about the findings of Italian food investigators. 60 Minutes asked them to conduct a blind taste test of three olive oil brands from U.S. supermarkets. The panel found two of the three brands to be low quality, but 60 Minutes did not reveal the labels of those bottles to viewers.

Beyond the reaction on social media, the broadcast also received a letter from the North American Olive Oil Association (NAOOA).

The letter took issue with journalist Tom Mueller, who said 75-80 percent of extra virgin olive oil bottles in the U.S. do not meet legal standards.

"Contrary to author Tom Mueller's opinion about rates of olive oil fraud, the NAOOA's experience is based on independent laboratory testing of hundreds of olive oils a year which consistently shows that more than 98% of the olive oils available are authentic, non-adulterated olive oil," the letter maintains.

Some 300,000 tons of olive oil are imported into the U.S. every year.
