MIAMI - Preliminary tests have found traces of anthrax in two more postal buildings that handled mail for American Media Inc., the supermarket tabloid company where a worker died of anthrax, state health officials said.

The facilities, in Boca Raton and Lake Worth, were being cleaned overnight and were expected to reopen on Friday. No employees were considered to be at risk, U.S. Postal Service spokesman Joseph Breckenridge said Thursday.

The scare in Florida began earlier this month when a photo editor at The Sun, an American Media tabloid, died of inhaled anthrax. A mailroom employee is infected with the disease, and co-worker has tested positive for exposure. About 400 other workers or visitors to the building are awaiting blood test results.

The National Enquirer, another American Media tabloid, came out on Thursday with its "world exclusive" _ "Bio-terrorism: The Florida anthrax attack on Enquirer headquarters."

It added a front-page disclaimer: "This paper not printed in the state of Florida."

The disclamer was meant to allay readers' fears that the anthrax spores found in the company's offices could somehow have made their way onto newsstand copies.

"There was concern expressed ... and AMI has gone out of its way to make sure there's no concern," said Gerald McKelvey, a company spokesman.

Four of the six tabloids that came out Thursday had stories on anthrax, which claimed the life of Sun photo editor Bob Stevens, 63.

The Enquirer story touts Stevens as "The man who saved America," since his death Oct. 5 alerted authorities to the anthrax danger. And it labeled its coverage as "From the people who lived through the nightmare. Their stories can save your life."

The Star interview with his widow, Maureen Stevens, included photos of Stevens cooking in his Lantana home, dancing with his daughter and dressing up as a clown on Halloween. The front page headline read: "MY HERO: Anthrax victim's widow: Her moving story. `Our last days together were filled with love.'"

The Globe had a two-column story written by Joe Mullins, a close friend of Stevens, which chronicled a fishing trip they had taken. However, the Sun, where Stevens himself worked, ran only a short, one column tribute to the often-smiling Briton.

Mailroom Ernesto Blanco, 73, the other person infected, remained hospitalized in Miami but was feeling better Thursday, two days after surgery to put tubes in his lungs to help him breathe, said his stepdaughter Maria Orth.

"He was feeling a lot of pain," she said. "But he's breathing much better."

While federal investigators in biohazard suits entered the closed American Media headquarters on Thursday for the second straight day, the tabloids continued their operations from temporary newsrooms in nearby Delray Beach and Miami.

Four of the tabloids had played up the attacks on their own headquarters, but two _ the National Examiner and Weekly World News _ stayed away from the topic.

The typically sensational Weekly World News stayed true to form with this headline: "Bigfoot kept lumberjack as love slave."
