TSA sounds alarm after World Cup fans pack their bags with American staple

The Transportation Security Administration (TSA) is issuing a serious warning to international World Cup visitors: Don't pack ranch dressing in your carry-on luggage.

As the World Cup brings millions of international visitors to the United States, many fans are trying out American staples — and, apparently, rushing to take them back home with them.

One European wrote on X, "Why did no one tell me ranch sauce is like crack? EUROPE WE NEED RANCH ASAP."

AMERICANS WARNED POPULAR TRAVEL ROUTES THIS SUMMER COULD CARRY CRIME AND KIDNAPPING RISKS

The enthusiasm hasn't gone unnoticed by U.S. officials.

On June 16 on Instagram, the TSA alluded to international travelers transporting bottles of ranch salad dressing through airport security.

"If you’re visiting for a very large sporting event & you happen to discover RANCH while you’re here ... please pack it in your CHECKED BAG on the way home," the post read.

The post added, "Days since the last airport ranch incident: 0."

On X, the TSA issued a similar warning and shared a photo of assorted oversized liquids — including a bottle of ranch dressing — next to a sign reminding travelers of the agency's 3.4-ounce liquid rule.

Many Americans got a kick out of the TSA's ranch warning.

"We should tell them about Chick-fil-A sauce that you can buy in large bottles, too!" one person said.

"Powdered ranch, guys! Powdered ranch," another Instagram user said.

A third person said, "This is the most American thing I’ve read today! God Bless America."

Others were stunned that the ranch dressing wasn't available abroad.

"Ranch in Europe is rare?! Poor Europeans," one person said.

"Who's going to start the ranch pipeline to Europe? Instant business opportunity."

Fox News Digital reached out to the TSA for comment.

The ranch craze is just one example of how international visitors have embraced American culture during the World Cup.

Earlier this week, Norwegian soccer fans went viral for performing synchronized "Viking rows" on Boston escalators.
