SAN DIEGO -- It’s been three weeks since the 10News investigation of floor bacteria in airport security lines.

Samples were taken where passengers have to remove their shoes, and the results were not pretty.

Because of the investigation, the San Diego Airport Authority is now taking steps to protect passengers.

“This is a good idea, because people are taking off shoes over there and some aren’t wearing socks,” said one passenger who was not wearing socks.

Lindbergh Field officials are providing surgical booties to protect bare feet after a 10News investigation found contagious molds, fungus and bacteria at security gates in San Diego, Las Vegas and Phoenix.

“I’m not being paranoid about these floors. I like this. I’m feeling better about it,” said traveler and bootie supporter Bonnie Linn.

10News brought their samples back to a lab and found many diseases travelers could be exposed to.

Since then, word has reached Mineta San Jose International Airport, where carpets are scrubbed and sanitized every night.

“The director of operations was wowed and said we have to do something about it,” said Rick Dressler of San Jose Airport.

Officials at San Francisco International Airport are reviewing their policy.

Lindbergh Field officials did their own lab testing, but have decided to act now in the best interest of public health.

“We will make these booties available to the traveling public,” said Diana Lucero of the San Diego Airport Authority.

The only problem was the kiosk with the booties at Lindbergh’s busiest gate to Southwest Airlines flights was tucked behind many security-warning signs.

“By the end of the week, we will have our results back and we will know what we are dealing and we will tweak as we go on,” said Xema Jacobson of the San Diego Airport Authority.

Jacobson said the airport is experimenting with the best place to display the booties.

However, not all of the locations work.

It will also take time for the public to catch on, though some already appreciate the effort.

“I have to protect my unborn baby,” said one pregnant traveler.

Free booties could wind up costing the Airport Authority millions of dollars per year, according to officials.

The Airport Authority will make its decisions after lab results come back Friday.
