Few travelers would expect a small Beagle to become the star of an international airport, but one remarkable detection dog recently did just that. Merla, a hardworking customs canine with an extraordinary sense of smell, captured widespread attention after uncovering an enormous stash of undeclared sandwiches hidden inside a passenger’s luggage. Her discovery not only sparked conversations online but also highlighted the important role airport detector dogs play in protecting agriculture, livestock, and the environment from potentially harmful products entering the United States.
The U.S. Customs and Border Protection (CBP) Office of Field Operations recently shared a photo of Merla, a friendly Beagle with an extraordinary nose, after she detected 100 pork and chicken sandwiches packed inside a traveler’s bags. The image showed the proud canine sitting beside two large bags filled with the confiscated food items.
CBP shared the story on Facebook on April 16 with a playful caption: “Though it might be stale at this point, lettuce remind you that you must declare agriculture items (including meats!) when entering the US.”
According to the agency, all 100 sandwiches were seized and ultimately destroyed.
The sandwiches appeared to be products from Le Pan, a popular Thai bakery whose packaged snacks are commonly sold in convenience stores such as 7-Eleven. While the sandwiches themselves were inexpensive, their contents posed a much bigger concern than their price tag suggested.
For Merla, it was just another day on the job. Yet her remarkable discovery quickly captured attention online, highlighting the incredible abilities of detector dogs who spend their days carefully inspecting luggage and cargo for restricted agricultural products.
A Powerful Nose Protecting America’s Farms
At first glance, confiscating food may seem harsh. However, agricultural restrictions exist for an important reason.
According to U.S. Customs and Border Protection, certain food products can carry plant pests or foreign animal diseases that threaten crops, livestock, and ecosystems. Even seemingly harmless items can introduce serious risks if brought into the country without proper inspection.
That is why travelers entering the United States must declare agricultural products, including meats, fruits, vegetables, seeds, plants, soil, animals, and animal-derived items. These requirements apply whether the items are packed in checked luggage, carried onboard, or transported in a vehicle.
When such products are discovered, agriculture specialists determine whether they meet entry requirements. If they do not, the items are confiscated to help prevent potential outbreaks or environmental damage.
Travelers who fail to declare prohibited agricultural products can face fines of up to $1,000 for a first-time, non-commercial offense. More severe penalties may apply in commercial cases.
Merla Joins a Long Line of Canine Protectors
Merla’s viral moment follows another recent success involving a detector eagle named Kokoe.
Earlier this year, Kokoe helped uncover undeclared food items carried by travelers arriving from Thailand. The seized products included mangoes, loquats, planting seeds, and chicken bouillon. Most of the items were destroyed after inspection, though officials allowed a piece of fried chicken and a quantity of betel nuts to continue on with their owners.
Stories like these offer a glimpse into the daily work performed by detector dogs across the country. Their keen sense of smell allows them to identify specific scents that humans would likely miss. Some can even detect tiny agricultural products hidden deep inside luggage within seconds.
While a customs officer may need several minutes to manually inspect a suitcase, a trained dog can quickly scan the same bag and alert handlers to potential concerns almost instantly.
From Rescue Dogs to National Heroes
The USDA launched its detector dog program, known as the Beagle Brigade, in 1984 at Los Angeles International Airport with just one eagle. Since then, the program has grown dramatically and now includes more than 180 detector dog teams working across the United States.
One of the most heartwarming aspects of the program is the fact that many of these canine recruits come from. According to CBP, detector dogs are often adopted from rescue shelters or donated by private owners before undergoing specialized training.
These dogs learn to identify agricultural products and signal their discoveries through trained responses. Some sit calmly beside suspicious luggage, while others gently paw at a bag to alert their handlers.
Beagles are especially well-suited for the role. Their exceptional sense of smell, compact size, friendly personalities, and strong food motivation make them ideal airport partners. They are approachable to travelers while remaining highly focused on their work.
For Merla, discovering 100 hidden sandwiches may have been routine, but her dedication serves as a reminder of the valuable role these dogs play every day. Behind every wagging tail is a highly trained working dog helping protect farms, livestock, and ecosystems, one suitcase at a time.
