Manhattan, NY — Insomnia Cookies, located at 17 West 125th Street in Harlem, was closed by the New York City Department of Health and Mental Hygiene (DOHMH) following an inspection on March 4, 2026. The establishment received a score of 99 points, well above the 28-point threshold for a Grade C, after inspectors documented sewage contamination in the food preparation area.

The closure marks a significant decline for the location, which had maintained Grade A scores as recently as November 2024.

What Inspectors Found

During the March 4 inspection, DOHMH inspectors identified one critical violation at the 125th Street location:

  • Sewage or liquid waste contamination: Food preparation areas, food storage areas, or other areas used by employees or patrons were found to be contaminated by sewage or liquid waste (violation code 04F).

This single critical violation resulted in the establishment's closure and accounted for the location's score of 99 points. The DOHMH noted that violations requiring immediate action were addressed at the time of inspection.

Sewage contamination in areas where food is prepared or stored represents one of the most serious conditions inspectors can document. The presence of sewage or liquid waste in food-handling environments poses direct risks of exposure to harmful bacteria, viruses, and parasites, including E. coli, Salmonella, and Hepatitis A.

Food Safety Context

NYC Health Code Article 81 establishes the sanitary standards that all food service establishments in New York City must maintain. Under these regulations, food preparation and storage areas must be kept free from contamination sources, including sewage and liquid waste. The presence of such contamination constitutes grounds for immediate closure to protect public health.

The FDA Food Code similarly requires that food establishments maintain plumbing systems that prevent sewage backflow and contamination of food-contact surfaces, food preparation areas, and food storage spaces. Properly functioning plumbing and waste disposal systems are considered foundational requirements for safe food service operations.

When the DOHMH determines that conditions at a food establishment pose an imminent threat to public health, inspectors have the authority to close the establishment immediately. The business must correct the cited violations and pass a re-inspection before it can reopen to the public.

A score of 99 points on a single critical violation reflects the severity with which DOHMH weights sewage contamination. For context, most routine inspections involve multiple minor and moderate violations that collectively produce scores in the range of 10 to 40 points. A single violation generating 99 points indicates a condition the Health Department considers among the most serious threats to food safety.

Inspection History

The March 2026 closure represents a notable departure from the location's recent inspection record. Prior DOHMH inspection results for this establishment include:

  • January 22, 2026: Score of 46 points (no grade assigned in available data)
  • November 19, 2024: Score of 13 points (Grade A)
  • May 2, 2023: Score of 5 points (Grade A)
  • September 21, 2022: Score of 23 points (no grade assigned in available data)
  • February 3, 2022: Score of 8 points (Grade A)

The January 2026 inspection, which produced a score of 46 points, indicated that conditions at the location had already begun to deteriorate prior to the March closure. The establishment had previously earned three Grade A ratings between February 2022 and November 2024, with scores ranging from 5 to 13 points during that period.

The jump from a score of 13 in November 2024 to 46 in January 2026, followed by a score of 99 and closure in March 2026, represents a rapid decline in inspection performance at this location.

Understanding NYC Restaurant Grades

New York City assigns letter grades to restaurants based on inspection scores. The grading scale is as follows:

  • Grade A: 0 to 13 points (lowest number of violation points)
  • Grade B: 14 to 27 points
  • Grade C: 28 or more points

Lower scores indicate fewer and less serious violations. A score of 99 points falls deep into Grade C territory, indicating significant food safety concerns at the time of inspection.

Restaurants that are closed by the DOHMH must correct all cited violations and pass a re-inspection before resuming operations. The re-inspection process verifies that the specific conditions that led to closure have been remediated.

Data and Resources

This inspection was conducted on March 4, 2026, with data released by DOHMH on March 6, 2026. Inspection results are public record and can be verified through the DOHMH restaurant inspection database.

Consumers can check the current inspection status of any New York City restaurant by visiting the DOHMH restaurant grades website or by looking for the posted letter grade at the establishment's entrance. The posted grade reflects the most recent graded inspection result.
