One of Waipahu's sandwich stops is on an unexpected timeout after state health inspectors slapped a red "closed" placard on the Subway at Kunia, saying its refrigerators were not keeping food cold enough to be safe. The July 17 action blocks the shop from preparing, serving or distributing food until fixes are made and inspectors clear it to reopen. A follow-up inspection is scheduled for July 21.
Department: Four Units Running Too Warm
In a routine check, inspectors found "improper cold-holding temperatures" and determined that all four on-site refrigeration units, including the walk-in, were running above the required range, according to the Hawaiʻi Department of Health. The outlet, operated by World Subs Inc., was immediately hit with a red placard on July 17 and must stay closed until those critical violations are fixed.
Inspectors told the operator that refrigeration has to reliably keep food at 41 degrees Fahrenheit or below before any subs can go back on the line.
Local Coverage And Timeline
The DOH notice identifies the temperature failures as the single critical violation that triggered the shutdown and lays out the timeline: inspection on July 17, red placard that same day, and a follow-up visit set for July 21 to verify corrections. Local outlet Honolulu Star-Advertiser reported on the closure as well, echoing the department's account.
Why A Red Placard Matters
A red "closed" placard signals what regulators consider an imminent public-health hazard that has to be fixed before a business can serve food again. Operators are typically required to toss any potentially compromised products and repair or replace equipment that is not doing its job.
For a look at how that placarding system has played out at other neighborhood spots, see this writeup on Bishop Street dim sum joint back open, and note that DOH rules specifically call for refrigeration that can hold TCS (time/temperature control for safety) foods at 41°F or below.
What Comes Next For The Shop
The operator must repair or replace refrigeration so it consistently holds food at or below 41 degrees Fahrenheit, then pass the follow-up inspection before the department will pull the red placard, according to the Hawaiʻi Department of Health. If inspectors verify the fixes on July 21, the shop can reopen. Until that happens, it is barred from preparing, serving or distributing food to the public.
We will update this story if the Hawaiʻi Department of Health or the store provides additional details on repairs or a reopening date.
