Flu Season & Food Safety: Why Employee Health Policies Matter More Than Ever

Every winter, kitchens brace for the same double hit: long hours and short staff. But when flu season arrives, the pressure to “just show up” turns into a real hazard. An employee coughing on the line or a dishwasher working through nausea doesn’t just risk spreading the flu — they can trigger foodborne illness outbreaks, too.

The reality is sobering: sick workers are one of the leading contributors to foodborne illness outbreaks in the United States. When flu season overlaps with norovirus season (November–April), the risk is amplified. And yet, many operators still lack clear policies — or the will to enforce them. The cost of a missed shift may feel heavy, but the cost of an outbreak can cripple a business.

Why Employee Health Policies Matter

The FDA Food Code requires that food workers with vomiting, diarrhea, jaundice, sore throat with fever, or infected wounds be excluded or restricted from work. These rules are designed to stop the spread of viruses like norovirus, hepatitis A, and influenza that can devastate an operation.

But enforcement falls on operators. Without clear policies, staff often feel pressured to work while ill. According to the CDC’s Environmental Health Specialists Network (EHS-Net), nearly 20% of restaurant workers reported working while experiencing vomiting or diarrhea in the past year — a staggering figure with direct consequences for guest safety.

Real-World Outbreaks Linked to Sick Workers

Chipotle, 2015: A norovirus outbreak in Boston sickened over 140 people, traced back to an ill employee handling food. The incident became a national headline and cost the brand millions.

Michigan, 2006–2010 (CDC data): Multiple norovirus outbreaks were linked to ill food workers in restaurants, confirming a clear epidemiological link between lack of exclusion and widespread illness.

When the Risk Is Highest

• January–March: Peak flu activity overlaps with norovirus outbreaks.
• Holiday hangover: Post-holiday staffing shortages increase pressure to work sick.
• Buffets & catering: High-volume events increase guest exposure if one worker is ill.
• Schools & healthcare facilities: Guests are especially vulnerable to flu and foodborne pathogens.

Best Practices: Building a Strong Employee Health Policy

1. Write it down

• Have a written, accessible policy outlining symptoms that require exclusion or restriction.

2. Train managers & staff

• Train staff to recognize symptoms in themselves and coworkers.
• Train managers to enforce exclusion consistently without retaliation.

3. Support sick leave

• Provide paid sick leave where possible, or build flexible coverage systems.
• Studies show paid sick leave reduces “presenteeism” — workers coming in sick because they can’t afford not to.

4. Use reporting tools

• Require employees to report illness before shifts.
• Keep illness logs as part of your food safety plan.

5. Plan for overlap

• During peak flu/norovirus season, build redundancy into scheduling. Expect higher absenteeism and prepare backup staff.

The Bigger Picture

Flu itself is rarely foodborne, but sick employees are often the vector for other pathogens — particularly norovirus and hepatitis A. A single ill worker can spread viruses to dozens of guests and coworkers, even without handling food directly.

Final Word: Safety Over Shifts

The flu is inevitable. Outbreaks from sick workers are not. By setting and enforcing strong employee health policies, operators can protect staff, guests, and their reputation. One missed shift may sting, but it’s nothing compared to the fallout from a preventable outbreak.
