Andy Warhol found artistic inspiration in a can of Campbell’s tomato soup. These days, some activists are finding sinister Muslim links in the same can.

Campbell Soup Co., the Camden, N.J., food giant, has been fighting a grass-roots boycott of its products after its Canadian subsidiary rolled out a line of soups certified as halal, meaning they’re prepared according to Islamic dietary laws.

Campbell Co. of Canada introduced the soups in a few Canadian markets in January, although American bloggers didn’t catch up to the news until earlier this month.

That’s when the tempest in a tomato-soup can started.

Blogger Pamela Geller began calling for a boycott earlier this month via her site, Atlas Shrugs. Other bloggers soon joined in.

The halal soups are available only in Canada. The company has no plans to offer a similar line in the U.S., said company spokesman John Faulkner.

Geller, who was instrumental in whipping up opposition to an Islamic community center and mosque in Manhattan, said she has no objection to the halal certification itself. Rather, she said, she opposes Campbell’s decision to have its Canadian products certified by the Islamic Society of North America, which government prosecutors alleged had ties to the terrorist group Hamas in a 2007 conspiracy case.

ISNA has denied ties to Hamas or to officials of a defunct charity called Holy Land Foundation, who were convicted in the conspiracy case. It has specifically condemned religious extremism and violence. In the wake of the conspiracy trial, Jewish and Protestant organizations issued statements in support of ISNA. An ISNA spokesperson was unavailable for comment.
