Wanna know more about what happened and how this affects bulk buyers and foodservice operators? Stick around—let’s dive in.
What happened?
On May 6, 2025, Las Vegas health officials began investigating five cases of gastrointestinal illness potentially linked to frozen half-shell oysters imported from South Korea. The common denominator? A batch processed by JBR (KR-15-SP), harvested from Designated Area No. 1 in Korea on January 6, 2025, and distributed to restaurants via California ports.
The oysters never made it to retail shelves—but if you enjoyed seafood at a Vegas restaurant in April and later experienced stomach issues, you might’ve met the wrong mollusk.

How was it discovered? Five Clark County residents reported symptoms such as vomiting, nausea, diarrhea, and abdominal pain after eating oysters. Although no hospitalizations occurred, officials are still investigating the origin of contamination and working with state and federal agencies.
What caused the issue?
This latest oyster-related recall has the seafood industry doing a double take—and not in a good way. The suspect? Norovirus, a microscopic menace that packs a gastrointestinal punch.
What Is Norovirus?
Norovirus is a highly contagious virus that can be transmitted through contaminated food, water, surfaces, or even just being in close proximity to someone infected. In the case of oysters, the virus often gets into the shellfish from sewage-contaminated waters, where filter-feeding mollusks can absorb and concentrate the virus in their tissues.
Once ingested—especially raw or undercooked—these oysters become mini viral grenades ready to detonate in unsuspecting stomachs.
Why It’s Dangerous
Norovirus causes acute gastroenteritis, which means serious stomach and intestinal inflammation. It’s notorious for rapid spread, especially in places like restaurants, hospitals, cruise ships, and schools.
Key health risks include:
- Severe dehydration from vomiting and diarrhea
- Increased complications for vulnerable populations
- Foodborne outbreaks if food handlers are infected
- Business liability and reputational damage for foodservice operators
Who’s at Risk?
While anyone can get norovirus, it hits some people harder than others:
- Older adults
- Pregnant individuals
- Children under five
- People with weakened immune systems
- Anyone with chronic gastrointestinal conditions
Common Symptoms (Usually within 12–48 hours of exposure):
- Nausea
- Vomiting
- Watery diarrhea
- Stomach cramps
- Low-grade fever
- Headache
- Fatigue
- Muscle aches
- Chills
It usually lasts 1–3 days, but the virus can continue to shed for days after symptoms subside.
10 common questions you may have
1. Is norovirus in oysters common?
Yes. Oysters filter large volumes of water and can concentrate viruses like norovirus if harvested from contaminated sources.
2. Can I get norovirus from cooked oysters?
Proper cooking kills the virus. Raw or undercooked oysters are the primary risk.
3. What temperature kills norovirus in seafood?
Heat oysters to at least 145°F (63°C) for 15 seconds to inactivate the virus.
4. How long after eating can symptoms appear?
Typically 12–48 hours after exposure.
5. How long does norovirus last?
Most people recover in 1 to 3 days, but they can still be contagious afterward.
6. Can norovirus be fatal?
It’s rarely fatal but can be dangerous for the elderly, infants, or those with compromised immune systems.
7. Can I get infected by touching a contaminated oyster shell?
Yes. Norovirus spreads via surfaces. Always wash hands and sanitize prep areas.
8. What should restaurants do if they suspect norovirus contamination?
Stop serving the product, discard it, sanitize all surfaces, and notify health authorities.
9. Should employees with symptoms still work?
No. Food handlers should not return to work until 48 hours after symptoms end.
10. How can I report a suspected illness?
Use the Southern Nevada Health District Foodborne Illness Form or call (702) 759-1300.
Here’s what you should do

If you’ve served or received oysters from JBR, here’s how to stay safe:
Check your product:
- Processor: JBR (KR-15-SP)
- Harvest Area: South Korea, Area No. 1
- Harvest Date: Jan 6, 2025
- Best By: Jan 6, 2027

Action steps:
- Stop serving immediately
- Check packaging for matching lot code
- Quarantine or discard affected stock
- Sanitize all prep areas
- Report illness: SNHD Form or call (702) 759-1300
A little caution now saves a lot of cleanup later.
Behind the brand
JBR (KR-15-SP) isn’t new to this conversation. Unfortunately, this isn’t the first time their oysters raised eyebrows: in April 2024, San Diego reports 11 norovirus cases tied to JBR oysters, and in December 2024, FDA issues warning about JBR oysters causing illness in Utah.
Similar recalls include:
- On March 11, 2025, Sea Win, Inc., a Los Angeles-based company, recalled 650 cases of its Frozen Half Shell Oysters due to potential norovirus contamination.
- On February 4, 2025, the Louisiana Department of Health (LDH) announced a recall of all oysters harvested from Area 3 (east of Lake Borgne and around the Chandeleur Islands) due to a norovirus outbreak.
- On January 12, 2025, Wang Globalnet voluntarily recalled frozen raw half-shell oysters processed by JBR due to potential norovirus contamination.
“Incidents like this underscore how important it is to maintain strong food safety standards from ocean to table. Whether it’s harvesting, handling, or shipping, every step must prioritize the well-being of the consumer. Staying transparent and taking preventive action are key to minimizing risk and making sure only safe, top-quality products hit the market.” Eran Mizrahi, Source86’s CEO.
The recurring theme? Imported seafood, especially raw shellfish, remains a high-risk category for contamination.
Ensuring safe eats
This recall is another reminder of the ongoing safety challenges in global seafood imports, especially when raw consumption is involved. For importers, co-packers, and foodservice operators, it’s a call to vet suppliers closely and implement traceability protocols.
Here’s what matters most:
- Ingredient integrity: Ensure suppliers follow strict harvesting and sanitation standards
- Transparency: Track origin, lot codes, and processing facilities
- Education: Teach foodservice teams about pathogen risks in high-risk products like oysters
