The Waiter Kept Coughing. Can a Florida Restaurant Be Liable?

A restaurant guest sees a server cough once and thinks little of it. A cough that continues through the meal may feel different. A cough that coworkers say persisted for weeks—and that management allegedly discussed with the employee—raises a harder question: when does an ordinary symptom become a danger a Florida business must address?

The Second District Court of Appeal confronted that question in Massaua v. Cervelli, a July 8, 2026 decision arising from two restaurant patrons’ tuberculosis diagnoses. The court did not decide that the restaurant caused either illness or that anyone was negligent. It decided something narrower but important: on the evidence presented, those questions could not be taken away from a jury at summary judgment.

That distinction matters to anyone evaluating a Florida restaurant illness lawsuit. A diagnosis alone does not establish a claim. The proof must connect what the business knew, what reasonable precautions called for, where the exposure occurred, and how the illness caused measurable harm.

Two dinners, one sick server, and diagnoses that came much later

The two plaintiffs did not know each other. One ate at the restaurant in November 2016 and the other in December 2016. The server was not diagnosed with tuberculosis until March 2017, and both patrons were diagnosed in 2018.

That gap in time made the case unusually difficult. The restaurant manager testified that the server did not appear sick while working there. But a former coworker described a heavy cough, said the server appeared visibly unwell for weeks, and recalled workplace tension concerning his health. The server testified that flu-like symptoms began in late September 2016 and continued while he worked at the restaurant.

The patrons also submitted an epidemiologist’s affidavit. After reviewing medical records and deposition testimony, the expert opined to a reasonable degree of medical certainty that the server had symptomatic tuberculosis when the patrons dined there and that their restaurant exposures caused their infections.

The trial court granted summary judgment for the defendants. The appellate court affirmed the judgment for the individual server because the patrons did not challenge that part of the ruling on appeal. It reversed as to the restaurant and its owner-manager, allowing those claims to continue.

The business did not need to know the exact diagnosis

The trial court had focused on whether management knew or should have known that the server had tuberculosis specifically. The Second District said that framed the duty too narrowly.

Florida businesses generally owe invitees a duty of reasonable care. In this setting, the relevant question was whether the restaurant knew or reasonably should have known that the employee had a contagious disease and whether allowing him to continue interacting with patrons and their food created a foreseeable zone of risk. The exact medical label belonged to the more specific causation inquiry, not the threshold duty analysis.

That does not mean every sneeze creates liability. The court emphasized evidence of duration, visibility, and context: testimony described a conspicuous respiratory illness lasting nearly three months, a small staff, complaints that the employee did not feel well, and exchanges between the employee and manager about his condition. From that combination, a jury could infer constructive knowledge even if management did not know the employee had tuberculosis.

The decision fits within the broader principles governing Florida premises-liability claims. A business may have actual knowledge because it or its agents know of a dangerous condition. Constructive knowledge can arise when a condition exists long enough that reasonable care should have uncovered it. In an infectious-disease case, however, the “condition” is not a puddle or broken stair. It may be a pattern of symptoms, workplace conversations, scheduling decisions, and a failure to respond.

Public-health rules inform the standard, but they do not automatically create a lawsuit

The appellate court cited the food-service rule in effect when the events occurred. That rule addressed people affected by communicable diseases or acute respiratory infections working where they could transmit illness. The court was careful to add that the rule did not create a private cause of action by itself. It illustrated and reinforced why an infectious employee can create a broader zone of risk.

Current Florida regulation likewise treats employee health as part of restaurant safety. Florida Statutes section 509.032 directs the Division of Hotels and Restaurants to regulate and inspect public food-service establishments to safeguard health and safety. The Division’s March 2026 administrative-rules compilation adopts specified portions of the 2017 FDA Food Code, including employee-health provisions. Its restaurant-operations guidance explains that food-service employees must report certain illnesses, symptoms, and exposures and that managers may need to restrict or exclude an employee.

A regulatory violation may be relevant evidence, but it does not erase the ordinary negligence elements. A claimant still must prove duty, breach, causation, and damages. The appellate decision in Massaua did not announce strict liability for restaurants and did not establish that a customer who becomes ill after dining out can presume where the infection occurred.

Causation is the second—and often steeper—climb

Duty asks whether the conduct created a foreseeable general risk. Proximate cause asks whether the particular act or omission foreseeably and substantially caused the particular injury. In an exposure case, that usually requires more than showing that an employee looked sick.

The patrons in Massaua offered a timeline, witness testimony, public-health investigation evidence, medical records, and an infectious-disease expert’s analysis. The appellate court concluded that this record created a genuine factual dispute. It did not decide whose evidence was more persuasive. At summary judgment, judges may not resolve conflicting testimony or choose which witness to believe.

A different case could fail if the symptoms were brief or invisible, if management had no reasonable opportunity to respond, if the claimant had several plausible sources of exposure, or if expert testimony could not reliably connect the illness to the business. The incubation period, mode of transmission, dates of visits, other contacts, strain or genotype evidence when available and admissible, and the quality of the medical differential all can matter.

This is why an exposure investigation has two parallel tracks. The first reconstructs notice inside the business: schedules, time records, manager texts, call-out logs, complaints, surveillance video, and testimony from coworkers or customers. The second reconstructs medical causation: symptom onset, diagnostic testing, treatment records, public-health communications, household and workplace exposures, and qualified expert analysis. Neither track can substitute for the other.

The evidence can disappear before the illness is identified

A person may not learn about a restaurant-linked exposure until a health department calls months later. By then, video may have been overwritten, employees may have left, and informal messages may be gone. Receipts, card statements, reservation confirmations, calendar entries, photographs, and location history can help establish when and where a person dined. Anyone contacted by public-health officials should preserve the communication and follow medical advice.

The same urgency applies to legal deadlines. Under the current version of Florida Statutes section 95.11, an action founded on negligence generally must be brought within two years. Section 95.031 generally measures accrual from when the last element of the claim occurs. Applying those rules to a latent illness can be fact-sensitive, and an old exposure date, later diagnosis, public-health investigation, or concealment allegation does not produce a safe do-it-yourself deadline. Prompt review is important even when the source is still being investigated.

What the decision changes—and what it leaves for another day

Massaua rejects an unrealistic demand that a restaurant identify the precise pathogen before it can have a duty to act. Reasonable care may require a response when conspicuous, persistent symptoms indicate a contagious condition even though the ultimate diagnosis is unknown.

But the ruling is procedural, not a verdict. The patrons survived summary judgment against the restaurant and manager; they did not win the underlying negligence claims. A jury may still reject notice, breach, causation, or damages after hearing the evidence. That boundary is the decision’s most useful lesson: Florida law can recognize the risk without assuming the result.

For an injured customer, the practical question is not merely, “Was an employee sick?” It is, “What did the business know or have reason to know, what did it do with that information, and can reliable medical evidence trace this illness to that exposure?” Those are evidence questions, and they become harder with every lost record and fading memory.
