Many Americans still think bright red tuna means it's fresher (it's not)
You know the tuna I’m talking about. It’s easy to mistake for a cube of watermelon. It’s the color of a Lyft logo. Appears to be glowing a vibrant, tantalizing purity. Tuna that bright red or pink means it’s… what, extremely fresh? Bursting with nutrients?
Nope. It means it’s got carbon monoxide.
I thought this was widely known, but a chef recently told me very few of his staff members were aware of this, and almost none of his customers. So, especially with the recent proliferation of poke joints, I thought I’d be helpful with this PSA of sorts.
Bright red or pink tuna means it has been gassed. In its natural state, fresh tuna is dark red, almost maroon, sometimes even chocolatey-looking.
Don’t worry, you most likely will have no ill effects from eating gassed tuna, according to the FDA. They have deemed carbon monoxided tuna as GRAS (Generally Regarded As Safe), though the practice is banned in Japan, Canada, and the EU. Plus, there is carbon monoxide in barbecue (given off by wood smoke).
But here’s why I personally tend to back away when I see bright red or pink tuna:
1. IT’S MUCH HARDER TO TELL IF IT’S FRESH OR NOT.
It can be left out for days and it will not turn brown. In one study, the University of Florida found that carbon monoxided tuna kept its bright red color for 11 days in the fridge. “The carbon monoxide actually hides the quality of a fish,” says Tommy Gomes, fifth-generation San Diego fisherman, host of The Fishmonger on Outdoor Channel, and owner of seafood shop Tunaville in Point Loma. “It’ll make a poor-quality fish pretty like a rose. I’ve seen them take an old piece of brown tuna [and] put the gas on it, and it comes out looking like cherry lemonade.” The gas also masks the smell of old tuna (which is one way you can tell if tuna’s getting past its eat-by stage). “Since there’s no smell, it falsifies the freshness,” Gomes explains.
2. I TRUST GOVERNMENT HEALTH ORGANIZATIONS, BUT ALSO RECOGNIZE THEY’RE NOT PERFECT.
The 1992 USDA food pyramid suggested carbs should be the bulk of our diet (they corrected that in 2005 and 2011). The government approved the fat substitute Olestra, which gave people all sorts of tummy issues. Margarine and other trans fats were also approved, then banned in May 2019. There are some smart humans in the government, but even geniuses make mistakes. So I tend to go with my gut: tuna in its natural state, or tuna treated with carbon monoxide? Easy choice.
So why gas tuna at all? Because of us. Consumers don’t like brownish fish. Tuna oxidizes quickly. It’s difficult for tuna fishermen and women to get it to market quick enough before it turns that brownish or chocolatey color. Customers erroneously think all brownish-looking fish is old or bad and will pay more for “fresher-looking” fish. So in the 1990s, the FDA allowed companies to gas the tuna and keep it artificially bright red for long stretches at a time.
“There’s nothing wrong with a hot chocolate–looking tuna loin,” says Gomes. “But, here in America, we want [it] seared on the outside, rosy pink on the inside.”
Gassed tuna is also often imported and less inexpensive than fresh, un-gassed tuna, says Gomes. “So, to be fair and honest,” Gomes acknowledges, “for families on a budget, gassed tuna is one of the best alternatives out there for frozen seafood.”
In the New York Times article cited above, a sushi restaurant owner reported his sales of tuna tripled when he started using gassed tuna. So that’s obviously good for the small business owner, as well as grocery stores. Food waste is a massive epidemic—the US throws out about half of edible seafood. If gassed tuna gets Americans to eat perfectly edible tuna they otherwise might throw out, that’s a step in a good direction.
But it’d be better if we as consumers knew that fresh, non-gassed tuna is supposed to be dark red or maroon—not bright red or watermelon pink, like a majority of the tuna I’ve seen at local poke shops. Ideally, we would look at a piece of bright red/pink tuna and think “Oh, hey there, carbon monoxide.”
The most important things about buying tuna is to trust the source (whether grocery store, fishmonger, or sushi joint). It also should be shiny and somewhat translucent, and not have slime or an off-smell.
Long live maroon tuna.

The annual event honors middle market companies creating jobs, scaling up, and investing in the region
San Diego is known for its startup culture and innovation economy, but what happens when the company moves beyond its early-stage years? The San Diego Business Impact Awards aim to answer that question, spotlighting the middle market businesses helping drive the region’s economy.
Hosted by San Diego Regional Economic Development Corporation (EDC) and JPMorganChase, the second annual awards celebration takes place on Thursday, July 23, from 4:30 to 7:00 p.m. at Scripps Research Auditorium. More than 200 executives, entrepreneurs, and business leaders are expected to attend the networking and cocktail event honoring some of San Diego County’s fastest-growing companies.
Businesses headquartered in San Diego County that have operated for at least two years are encouraged to submit their nomination by Thursday, June 18 at 4 p.m. Companies across industries—from technology and life sciences to tourism and consumer products, as well as pre-revenue startups—are eligible for recognition.
For EDC President and CEO Mark Cafferty, the event is as much about building connections as celebrating success. “We’ve had a longtime partnership with JPMorganChase; their work aligns with our efforts to support underserved communities and drive talent development,” says Cafferty. “And the networking was invaluable last year. I’m still in touch with people I met at last year’s awards.”
EDC is an independently-funded nonprofit that works directly with San Diego companies to help them grow the local economy, make the region as a whole more competitive, and attract and retain top-tier talent with quality jobs. Through EDC, companies can get help starting or expanding their business with support for things like site selection, permit navigation, and regulatory guidance, plus connections to local resources and potential business collaborators.
The San Diego Business Impact Awards began as an idea with one of EDC’s longtime strategic partners, JPMorganChase. The two organizations share a commitment to San Diego and are dedicated to bolstering middle market businesses.
“We’re blessed with a robust innovation economy and startup community,” says Aaron Ryan, San Diego Region Manager for JPMorgan’s Commercial and Investment Bank and vice chair of the firm’s’ San Diego Market Leadership Team. “But one of the segments of the business community we felt was overlooked was emerging middle market companies—the businesses that are no longer small but not yet large.”
Ryan says supporting those companies is critical as they scale and decide where to invest, hire, and grow.
San Diego’s high cost of living remains one of the region’s biggest business challenges, making talent recruitment and retention increasingly competitive. But local leaders point to the region’s quality of life, climate, and collaborative business community as advantages that continue to attract employers and workers.
“In order to support thriving households, there has to be enough high-quality jobs for people to be able to afford to live here,” Cafferty says. “Once a company grows and excels past that middle market point in their growth cycle, they become much more likely to pay higher wages and compete globally.”
Both Cafferty and Ryan proudly tout the unique collaboration that exists among San Diego County businesses. Bringing together top universities producing high-quality talent, cutting-edge research institutions, a robust military and defense presence, leading ocean science and environmental organizations, and a binational, cross-border identity creates a distinct business ecosystem that defines and strengthens the San Diego region.
Last year’s San Diego Business Impact Awards celebrated nearly 60 honorees from 49 industries, representing a total of 8,232 jobs across eight sectors, including: software and technology, healthcare and life sciences, consumer goods, professional services, finance, construction and manufacturing, defense, and hospitality and tourism. On average, honoree companies doubled their revenues over the previous year, employed more than 145 San Diegans each, and offered an average annual compensation of $192,415.
Top honorees included defense contractor Innoflight, environmental consulting firm Bancroft Construction Services, life sciences startup Element Biosciences, defense technology contractor GALT Aerospace, organic grocery store chain Jimbo’s, and biopharmaceutical company LENZ Therapeutics. During the event, Innoflight Founder and CEO Jeff Janicik held a fireside chat offering his insights on investing in the community and embracing San Diego culture.
This year, organizers hope to continue highlighting the middle market players driving economic impact across the region. Nominations are now open through June 18 at 4 p.m. Get your tickets to the San Diego Business Impact Awards celebration to enjoy drinks by Snake Oil Cocktail Co., light bites, live music, and networking.
Scripps study shows that some patients may be able to taper their dose and maintain results
While glucagon-like peptide-1 (GLP-1) receptor agents have been used to treat Type 2 diabetes for more than 20 years, their recent emergence as weight-loss wonder drugs marked a new frontier in medicine. But their effectiveness has left some patients wondering what to do once they’ve reached their goal. Stopping the medication could mean regaining some, if not all, of the weight. A Scripps Clinic internal medicine physician recently conducted a small study of whether GLP-1 patients who had reached their goal weight could maintain that weight by taking their regularly prescribed injection every other week instead of weekly. Spoiler alert: 30 of 34 patients did. Read more about the study here and what that may mean as pharmaceutical companies roll out oral GLP-1s.
