Who Should Not Eat Squid Patties During a Halong Day Trip? Safety Tips for Travelers

When travelers think of a Halong day trip, visions of emerald waters, limestone karsts and fresh seafood quickly come to mind. Among the region’s most celebrated delicacies is chả mực—the famous Halong squid patty. Crispy, chewy and deeply flavorful, it’s a must-try for most visitors.
But here’s a little-known fact: not everyone should indulge in this iconic treat. For some, squid patties may cause health discomfort or even ruin the entire day trip. If you’re planning a Halong Bay tour and wondering whether it’s safe to try them, this guide is for you.
Halong Day Trip & Its Famous Squid Patties
Why squid patties are Halong’s signature street food
Squid patties or cha muc Halong are made from freshly caught squid, finely minced and hand-pounded until springy. They’re then fried until golden and served with sticky rice, banh cuon (steamed rice rolls) or dipped in chili fish sauce.
Locals take pride in their squid patties, with many claiming that Halong’s version is the best in Vietnam. The chewy texture and smoky flavor come from squid caught in the bay’s cool waters.
Where travelers usually enjoy them
On a Halong day trip, visitors often encounter squid patties in:
-
Bustling food markets near Bai Chay and Hon Gai.
-
Street stalls lining Halong streets.
-
Cruise tours, where onboard chefs prepare them fresh.

The cultural experience of tasting squid patties
Beyond taste, squid patties embody Halong’s food culture. Sharing a plate of golden patties while cruising past limestone cliffs connects travelers to the local way of life. For many, it’s as memorable as exploring Sung Sot Cave or riding the Queen Cable Car.

Who Should Avoid Eating Squid Patties on a Halong Day Trip
While most travelers can safely enjoy squid patties, some groups should be cautious:
People with seafood allergies
If you’re allergic to seafood, squid patties are a clear no-go. Even small traces of squid protein can trigger reactions, from mild rashes to severe anaphylaxis. Since Halong kitchens often prepare squid alongside shrimp, fish and clams, cross-contamination is also a risk.
Travelers with sensitive stomachs or digestive issues
Street food in Halong is delicious but may be oily or spiced differently than what your stomach is used to. If you often get food poisoning or digestive discomfort while traveling, it might be safer to skip fried squid patties and opt for steamed seafood instead.
Pregnant women and elderly travelers
Pregnant women are advised to limit seafood intake, particularly shellfish and squid, due to mercury and bacteria risks. Elderly travelers, too, may find squid patties heavy or difficult to digest. A Halong day trip is already packed with sightseeing, so avoiding foods that could upset digestion ensures a smoother experience.
Those on strict diets
Vegetarians, vegans or those observing halal/kosher restrictions won’t find squid patties suitable. Luckily, Halong offers plenty of alternative dishes that fit these diets.
