Greenpoint Wedding Norovirus Outbreak Sickened 30+ Guests, Bride and Groom Sue Hotel

Michael Ahern and his wife spent their honeymoon glow bedridden with vomiting, diarrhea, chills, and fatigue instead of celebrating their new marriage. Now Ahern is suing the Greenpoint, Brooklyn venue that catered their November 30, 2024 wedding reception, claiming a norovirus outbreak tied to the event left him and dozens of other guests violently ill.

Ahern filed the lawsuit against The Box House Hotel LLC in Manhattan Supreme Court on Monday, seeking damages to be determined at trial, according to The Independent. The Box House Hotel, a converted former window and door factory at 77 Box Street featuring a 10,000-square-foot event space with a retractable roof, hosted the couple's reception; the venue can accommodate up to 293 to 400 guests, per Wedy. The couple paid the hotel roughly $30,000 to cater the wedding, the outlet's reporting notes.

The Aherns began experiencing nausea and vomiting the night after their Saturday reception, and by December 2, 2024, both were bedridden, with Ahern missing work that day. The couple's stool samples later tested positive for norovirus, and they were far from alone: more than 30 of the 112 wedding guests developed norovirus-type symptoms, with 31 attendees reporting acute gastrointestinal illness over the following day or two.

Health Department Traces Outbreak to Kitchen Failures

The New York City Department of Health investigated the outbreak and, in a report issued in September 2025, identified multiple deficiencies in the hotel restaurant's food-safety and sanitation practices. Investigators found the restaurant kitchen lacked hand soap and lacked a proper thermometer for determining food temperatures, violations that were later cited against the hotel for both the kitchen and bar area.

The department's Bureau of Communicable Disease conducted telephone interviews with attendees and distributed stool sample kits to six food handlers. All of the guests who fell ill had eaten prosciutto, macaroni-and-cheese croquettes, and a seasonal crumble dessert, though the health department's report ultimately concluded that the specific food vehicle responsible for the outbreak remained undetermined.

Investigators did identify a norovirus-positive employee among the food handlers, but that employee had not prepared the three dishes tied to the illnesses and had not reported being sick before working the event, according to the report. The department's findings stated the outbreak was likely caused by food contaminated by that norovirus-positive food handler. The Brooklyn Lantern, which provided all food and drink for the Saturday night reception, was also visited by a health department inspector for an environmental review as part of the investigation.

Hotel Points to Winter Surge and Clean Recent Record

A spokesperson for The Box House Hotel said the hotel is sorry guests got sick and argued that norovirus was widespread across New York City that winter. That claim lines up with regional data: the month after the wedding, December 2024, New York City saw a surge in norovirus cases with nearly 1,300 reported infections, marking the highest national level recorded since 2012, as Hoodline previously reported.

The spokesperson also said the hotel cooperated fully with the health department's investigation, disinfected the restaurant and event spaces at the department's request, and retrained staff on handwashing and illness reporting. The hotel restaurant scored an A on its next inspection and retains that A rating today. The venue reports no prior outbreak before the wedding incident and no additional outbreaks since, and health investigators similarly identified no further illness linked to The Box House Hotel or the Brooklyn Lantern after the event. The hotel says it has hosted nearly 1,000 weddings and events over the past 15 years. Food and beverage service at the venue is run by Room 11 Hospitality, a Brooklyn-based hospitality group that also operates the Henry Norman Hotel and Franklin Guesthouse, according to Forbes. The hotel now has roughly three weeks to file a formal answer in court.

Why a Single Sick Worker Can Sicken Dozens

The outbreak illustrates a pattern documented nationally in banquet and catering settings. The CDC estimates norovirus is the leading cause of foodborne illness in the United States, responsible for 58% of domestic food-related illnesses and roughly 2,500 outbreaks annually, and the virus causes an estimated 19 million to 21 million illnesses, 109,000 hospitalizations, and 900 deaths each year nationwide, according to the CDC.

A CDC analysis found that over 60% of foodborne norovirus outbreaks occur in restaurant or catering settings, and 70% of those are caused by infected food workers touching ready-to-eat items with bare hands, per CIDRAP. Research from the University of Florida IFAS Extension notes that as few as 18 viral particles can trigger acute gastroenteritis, which helps explain how a single food handler's lapse can sicken dozens of guests at one event. Separately, a study cited by Newsday found only 16% of restaurants involved in outbreaks had comprehensive written policies barring sick employees from working, underscoring how informal sick-leave practices in the food service industry can let ill staff continue handling food.

Under New York City Health Code requirements, food service establishments must keep handwashing sinks fully stocked with soap and running water and are legally obligated to exclude food handlers who are experiencing acute gastrointestinal symptoms. Those are the same categories of violation health investigators say they found at The Box House Hotel's kitchen following the wedding outbreak. The case adds to a string of group-setting illness outbreaks Hoodline has tracked in the region, including a norovirus scare that disrupted NYC sleepaway camps this summer.
