Clark Pederson Faces Life-Threatening Infection After Deck Injury – Will He Make It Back to Shore in Time?

From Bad to Worse: Clark Pederson’s Knife Wound Becomes a Full-Blown Infection Crisis on Deadliest Catch

The Bering Sea doesn’t forgive hesitation, and in Season 21 of Deadliest Catch, Clark Pederson learned that lesson the hardest way possible.

What started as a deep, bloody slice across the base of his thumb during routine bait-cutting quickly spiraled into one of the most frightening medical emergencies the F/V Northwestern has faced in years. Within 48 hours of the initial accident, the wound turned angry: hot, swollen, and laced with the tell-tale red streaks that every crab fisherman dreads—classic signs of a rapidly advancing infection.

Out on the remote Western Grounds—more than 300 miles from Dutch Harbor and battered by 30-foot seas—the Northwestern was effectively cut off from immediate medical care. Saltwater, fish slime, sub-freezing air, and constant immersion in bait tanks created the perfect breeding ground for bacteria. As veterans know, hand infections at sea can escalate from painful to life-threatening in a matter of hours.

Clark, the stoic deckhand who married Captain Sig Hansen’s daughter Mandy in 2017 and has become a fan favorite for his quiet competence, tried to tough it out. Fishermen are wired that way. He wrapped the hand tighter, swallowed the pain, and kept pulling pots. But the infection didn’t care about grit. By the second night, he couldn’t close his fist. Pain shot up his forearm with every movement. Fever crept in. Even simple tasks—tying knots, coiling line—became impossible.

Mandy, who had flown home earlier in the season after successfully captaining the boat solo during king crab, was monitoring everything from shore. When the satellite calls started coming in describing red streaking and swelling that was “blowing up like a balloon,” she went into crisis mode.

“Clark was still trying to work,” Mandy later told producers, voice cracking. “He kept saying, ‘I’m fine, we can’t lose the string.’ But I’ve seen enough injuries on that boat to know what was happening. Those red lines don’t lie. That’s blood poisoning.”

On deck, the mood turned grim. Deck boss Nick Mavar and the rest of the crew quietly urged Sig—who was temporarily running the boat while Mandy was home—to make the call. Turning back meant abandoning prime fishing grounds during one of the best bites in years. It meant burning tens of thousands of dollars in fuel and lost crab. It meant the season could effectively be over.

But the alternative was unthinkable.

Sig, who has lost friends to sepsis and seen careers ended by infected hands, didn’t hesitate long. “We’re not gambling with a man’s life for crab,” he barked over the radio. The Northwestern pointed east and began the long, punishing steam toward Dutch Harbor.

The journey took nearly two full days in mountainous seas. Clark spent most of it in his bunk, hand elevated, fighting waves of nausea and chills while the crew rotated ice packs and pumped him full of the strongest oral antibiotics the boat carried. Every hour on the sat phone with doctors onshore brought the same warning: if the streaking reached his wrist or fever spiked higher, they were looking at sepsis—and possible medevac by Coast Guard helicopter in 50-knot winds.

When the Northwestern finally tied up at the dock in Dutch Harbor, Clark was rushed to the clinic. Doctors didn’t sugarcoat it: the wound was badly infected with a nasty mix of marine bacteria, including Vibrio species that thrive in cold saltwater. IV antibiotics were started immediately. Had they waited even one more day, surgeons said, amputation might have been on the table.

After a week of heavy-duty treatment, Clark was released with a clean bill of health—but a permanent warning. Repeated immersion in freezing seawater could trigger reinfection. Scar tissue had already reduced flexibility in his thumb. Grip-strength tests showed he’d lost nearly 30 percent on that hand. Another serious cut or crush injury, doctors said, and the damage could be irreversible.

For a 30-something deckhand whose entire identity is built on pulling 900-pound pots in 40-below wind chill, the prognosis hit like a rogue wave.

“I’ve broken bones, torn ligaments, been pinned under pots,” Clark said in a raw confessional after returning home to Seattle. “But this is the first time a doctor looked me in the eye and said, ‘Your hand might not hold up anymore.’ That’s… that’s hard to hear.”

The injury forced difficult conversations within the Hansen family. Sig, now in his 60s and thinking seriously about retirement, has long planned for Mandy and Clark to eventually take over the Northwestern. But with Clark’s hand compromised, questions about long-term deck work—and who will lead the crew—have suddenly become urgent.

Mandy, watching her husband wrestle with the idea that his career on deck might be shortened, admitted the scare changed everything. “I captained that boat to prove I belong,” she said. “But seeing Clark hurt like that… it makes you realize crab isn’t worth losing the people you love.”

As Season 21 continued into the opilio stretch, Clark returned to the boat wearing a reinforced glove and under strict orders to stay out of the bait station. Viewers watched a visibly more cautious deckhand—and a captain who now flinches at every wince from her husband.

The knife slipped for only a second. The infection raged for days. And the consequences will last a lifetime.

In the end, the Northwestern still filled its tanks and finished the season strong. But for Clark Pederson, a tiny blade left a wound far bigger than anyone could have imagined—one that may eventually force him off the deck he’s called home for over a decade.

The Bering Sea gave him his life back. The question now is how much longer it will let him keep the job he loves.
