Personal hygiene and illness reporting

▶ Video coming soon A video version of this lesson is on the way.

Every food that leaves Juniper Street's kitchen passes through someone's hands. Most of the time those hands are the last thing that touches the food before a guest eats it. That makes the people in the kitchen both the strongest barrier against foodborne illness and one of its main sources. Norovirus, hepatitis A, Shigella and some strains of E. coli and Salmonella are spread mostly by infected people, often through tiny amounts of feces on hands that looked clean. One sick cook working a busy Saturday can make dozens of people ill.

This lesson covers the habits that keep food workers from contaminating food: handwashing, hand care and gloves, clothing and hair, and eating and drinking at work. It then covers the hardest part of personal hygiene for many kitchens: telling a manager when you are sick and staying away from food until it is safe to come back.

Why people are a source of foodborne illness

Bacteria and viruses live on and in the human body. Staphylococcus aureus is carried in the nose and on the skin of a large share of healthy people and in infected cuts and burns; if it gets into food that is then held warm, it makes a toxin that cooking does not destroy. Norovirus is shed in enormous numbers in the vomit and stool of an infected person, and only a few virus particles are needed to make someone else sick. People can shed norovirus for days after they feel better, and some people who carry hepatitis A or Salmonella have no symptoms at all.

That is why food safety rules focus on two things at once. Routine hygiene, done by everyone all the time, reduces the germs that healthy workers carry. Illness rules keep people who are likely to be shedding large numbers of germs away from food. The Food Code makes the person in charge responsible for both: training food employees, watching that they wash their hands, and making sure they report illnesses and are excluded or restricted when they must be.

Handwashing

Handwashing is the single most important habit in a kitchen. Done properly, it removes most of the bacteria and viruses picked up from raw food, surfaces and the body. Done badly, it gives a false sense of safety. The steps are simple, but each one matters.

Six steps of handwashing at a dedicated hand sink, taking at least 20 seconds: wet hands with warm running water; apply soap from the dispenser; scrub for 10 to 15 seconds, including the backs of the hands, between the fingers and under the nails; rinse with fingers pointing down; dry with a single-use paper towel; and turn off the tap with the towel. Beside the steps is a list of when to wash hands: when starting work or coming back from a break, after the washroom, after touching raw meat, poultry or fish, before putting on gloves, after touching the face, hair or phone, after taking out garbage or cleaning, after eating, drinking or smoking, and when switching between tasks.
The handwashing steps and the moments when hands must be washed, as posted above Juniper Street's hand sinks.
  • Wet hands and exposed arms with clean, running warm water.
  • Apply soap and lather.
  • Rub vigorously for at least 10 to 15 seconds, paying attention to the fingertips, under the nails and between the fingers. The Food Code requires the whole cleaning procedure to take at least 20 seconds.
  • Rinse thoroughly under clean, running warm water.
  • Dry with single-use paper towels or a hand dryer. Shared cloth towels are not allowed.
  • Use a paper towel or other barrier to turn off the faucet and open the door if the hands could be contaminated again.

Where to wash

Hands are washed only at a designated handwashing sink, never in a food prep sink, a ware-washing sink or a service sink. The Food Code requires handwashing sinks to be conveniently located, supplied with water at 100 °F or warmer, soap, single-use towels or a dryer, a waste container and a sign telling employees to wash their hands, and to be kept accessible at all times. A hand sink blocked by a bus tub, a rack of glasses or a stack of boxes is a violation, as Juniper found in its spring inspection.

Juniper has four hand sinks: at the raw station, on the line, in the dish pit and behind the bar. Each one is stocked at opening and checked at every shift change. The rule that people find hardest is that nothing else goes in a hand sink: no rinsing ladles, no dumping ice, no filling buckets. Once a hand sink is used for something else, people stop thinking of it as the place to wash hands.

When to wash

The poster above each sink lists the moments when hands must be washed. They come down to one principle: wash hands whenever they may have picked up something that should not reach food, and always before starting work with ready-to-eat food. In practice a line cook at Juniper washes hands dozens of times a shift. The busiest moments, such as switching from handling raw patties to plating, are exactly when people are tempted to skip it.

Hand sanitizer

Hand antiseptics such as alcohol-based sanitizer are not a substitute for handwashing. The Food Code allows them only after hands have been properly washed, and the product must be approved for use in food establishments. They do not remove grease, food residue or dirt, and they work poorly against norovirus.

Checking that it happens

Most managers believe their staff wash their hands well. Observation usually shows otherwise. Juniper's safety committee runs a short observation audit every month: during a busy lunch, Aisha or Kofi watches the kitchen for an hour and records each moment when hands should have been washed and whether they were. The program below summarizes one audit. It is not about catching people; the results are shared with the whole team and used to fix the obstacles, such as a hand sink in an awkward place or towels running out.

# Summarize a handwashing observation audit (one busy lunch hour).
observed = [
    # (worker, moment, washed?, at least 20 seconds?)
    ("Ben",  "after raw patties, before plating", True,  True),
    ("Ben",  "after raw patties, before plating", False, False),
    ("Hana", "after touching phone",              True,  False),
    ("Hana", "returning from break",              True,  True),
    ("Luis", "after raw chicken, before greens",  True,  True),
    ("Luis", "after taking out garbage",          True,  True),
    ("Noah", "before putting on gloves",          False, False),
    ("Noah", "after raw patties, before plating", True,  True),
    ("Maya", "returning from break",              True,  True),
    ("Kofi", "after dirty dishes, before clean",  True,  False),
]

total = len(observed)
washed = sum(1 for o in observed if o[2])
good = sum(1 for o in observed if o[2] and o[3])
print(f"Moments observed: {total}")
print(f"Hands washed: {washed} ({100 * washed // total}%)")
print(f"Washed well (20 s or more): {good} ({100 * good // total}%)")
missed = {}
for worker, moment, w, ok in observed:
    if not (w and ok):
        missed[moment] = missed.get(moment, 0) + 1
print("Moments to work on:")
for moment, n in sorted(missed.items(), key=lambda kv: -kv[1]):
    print(f"  {n} x {moment}")
Output
Moments observed: 10
Hands washed: 8 (80%)
Washed well (20 s or more): 6 (60%)
Moments to work on:
  1 x after raw patties, before plating
  1 x after touching phone
  1 x before putting on gloves
  1 x after dirty dishes, before clean

Hands were washed at eight of the ten moments, but only six of the washes were long enough. The committee found that the hand sink on the line is beside the fryers, so cooks rushed to get away from the heat. A second hand sink near the pass was added to the summer repair list, and in the meantime the paper towel dispenser was moved so cooks could dry their hands while stepping back from the fryers.

Hand care, gloves and jewelry

Clean hands start with short, clean fingernails without polish or artificial nails, which can chip into food and hold dirt underneath. Cuts, burns and sores on the hands are a special risk because they are often infected with Staphylococcus aureus. A food worker with a wound on the hand or wrist covers it with a clean, waterproof bandage and then wears a single-use glove over it. A wound that is infected, oozing or cannot be covered well means the worker is moved away from food until it heals.

The Food Code forbids food employees from wearing jewelry, including medical information jewelry, on their arms and hands while preparing food, except for a plain ring such as a wedding band. Juniper's rule is the same for the kitchen and the bar.

Gloves were covered in Lesson 7. The short version is that gloves are changed as often as hands would be washed, and that hands are washed before putting on a new pair. Gloves can make people careless: a cook wearing gloves may touch raw meat, a phone and a salad without thinking, because the gloves feel like protection.

Clothing, hair and personal habits

Clean outer clothing, changed when it gets dirty, keeps dirt and germs from street clothes and from raw-meat work away from food. Aprons are taken off before going to the washroom or taking out the garbage. Hair is held back with a hat, hairnet or band, and beards are covered with a beard net where the local authority or the house rules require it, because hair falls into food and people touch their hair without noticing.

Eating, drinking and using tobacco are done only in designated areas where food, clean equipment and single-service articles cannot be contaminated. The Food Code allows a worker to drink from a closed container with a lid and a straw, handled so that the hands and the container do not contaminate food. Coughing or sneezing is done into a tissue or the elbow, followed by handwashing.

Reporting illness

Hygiene rules cannot make a sick worker safe. A person with norovirus who vomited before the shift may be shedding billions of virus particles, and no amount of handwashing will bring that down far enough. The only safe answer is to keep the person away from food, and that depends on the person telling a manager.

The Food Code requires food employees and conditional employees to report certain symptoms and diagnoses to the person in charge, and requires the person in charge to exclude or restrict them. Workers must report vomiting, diarrhea, jaundice, a sore throat with fever, and an infected cut or boil on the hands or arms. They must also report a diagnosis with any of the Big 6 pathogens: norovirus, hepatitis A virus, Shigella, Shiga toxin-producing E. coli, Salmonella Typhi and nontyphoidal Salmonella, and certain exposures, such as eating at an event linked to an outbreak or living with someone diagnosed with one of them. The person in charge must notify the health department when a worker has jaundice or is diagnosed with one of the Big 6.

What the worker hasFood Code actionWhen they can return to food work
Vomiting or diarrheaExclude24 hours after symptoms stop, unless a Big 6 diagnosis applies
JaundiceExclude and notify the health departmentWith approval from the health department
Diagnosed with a Big 6 pathogenExclude (or restrict, for some cases without symptoms) and notifyUnder the Food Code criteria for each pathogen, usually with approval
Sore throat with feverRestrict from food; exclude if serving a highly susceptible populationWith a medical note or a negative test
Infected wound or boil on the hand or armRestrict unless covered with an impermeable cover and a gloveWhen it is healed or properly covered

Exclusion means the worker may not work in the establishment at all. Restriction means the worker may work but not with exposed food, clean equipment or utensils, or unwrapped single-service items; for example, a restricted worker might take out the recycling or work the host stand. For vomiting and diarrhea the Food Code requires exclusion, because the person will also contaminate washrooms, door handles and the staff area.

# A decision aid for illness reports at Juniper (simplified from the Food Code).
from datetime import datetime, timedelta

def decide(symptom, last_symptom=None):
    if symptom in ("vomiting", "diarrhea"):
        back = last_symptom + timedelta(hours=24)
        return "exclude", f"may return {back:%a %b %d %I:%M %p} if well"
    if symptom in ("jaundice", "diagnosed"):
        return "exclude, notify health department", "return only with approval"
    if symptom == "sore throat with fever":
        return "restrict from food", "medical note or negative test"
    if symptom == "infected cut":
        return "restrict unless covered and gloved", "until healed"
    return "no action needed", "-"

reports = [
    ("Noah", "vomiting", datetime(2026, 6, 6, 3, 30)),
    ("Hana", "sore throat with fever", None),
    ("Rafael", "infected cut", None),
    ("Chloe", "diagnosed", None),
]
for name, symptom, last in reports:
    action, ret = decide(symptom, last)
    print(f"{name:7s} {symptom:24s} -> {action}; {ret}")
Output
Noah    vomiting                 -> exclude; may return Sun Jun 07 03:30 AM if well
Hana    sore throat with fever   -> restrict from food; medical note or negative test
Rafael  infected cut             -> restrict unless covered and gloved; until healed
Chloe   diagnosed                -> exclude, notify health department; return only with approval

Making reporting work

Rules on paper do nothing if workers come in sick anyway. People come to work ill because they cannot afford to lose the shift, because they are afraid of letting the team down on a busy night, or because they think their symptoms are nothing serious. Restaurants that want honest reporting make it easy and safe to report. Juniper's approach has four parts.

  • Every new worker signs an employee health agreement at orientation, as the Food Code expects, and is told in person that calling in sick with vomiting or diarrhea is expected, not punished.
  • The manager on duty asks the question at the start of every shift: any vomiting, diarrhea, fever with sore throat, or yellow skin or eyes since your last shift?
  • Elena, the owner, pays shifts lost to a reportable illness, because Georgia has no general paid sick leave law for private employers and the restaurant does not want people choosing between rent and public health.
  • Managers arrange cover through a group chat rather than pressuring the sick worker to find a replacement.

When Noah called at 6 a.m. on a Saturday in June to say he had been vomiting overnight, Daniel thanked him, told him to rest, and asked him to call again on Monday. He checked with the rest of the line whether anyone else felt ill, had the staff washroom cleaned and disinfected using the vomit cleanup procedure from Lesson 9, and noted the call in the illness log. No guests became ill. That is what a working reporting system looks like: unremarkable.

Summary and key terms

  • Food workers can carry and spread norovirus, hepatitis A, Shigella, Salmonella, E. coli and Staphylococcus aureus even when they feel well.
  • Wash hands at a dedicated hand sink for at least 20 seconds, including 10 to 15 seconds of scrubbing, at every moment when hands could contaminate food.
  • Keep nails short, cover hand wounds with a waterproof bandage and a glove, remove jewelry, wear clean clothing and restrain hair.
  • Workers must report Big 6 diagnoses and key symptoms; vomiting and diarrhea mean exclusion until 24 hours after symptoms stop, and jaundice or a Big 6 diagnosis means notifying the health department.
  • Reporting works only when workers trust that they will not be punished or lose pay for telling a manager they are sick.
Hand sink

Keeping a sick worker out of the food business entirely until it is safe for them to return.
Restriction
Keeping a worker away from exposed food and clean equipment while allowing other duties.
Big 6
Norovirus, hepatitis A virus, Shigella, Shiga toxin-producing E. coli, Salmonella Typhi and nontyphoidal Salmonella, the pathogens most easily spread by food workers.
Jaundice

Common mistakes

  • MistakeHand sanitizer gel is a quick substitute for washing between tasks.

    InsteadSanitizer does not remove grease or food and works poorly on norovirus; wash at the hand sink, and use sanitizer only afterwards if at all.

  • MistakeA cook who stopped vomiting this morning and feels fine can work the dinner shift.

    InsteadPeople stay infectious after symptoms stop; the worker stays home for the full waiting period.

  • MistakeRinsing a ladle in the hand sink is harmless when the dish pit is busy.

    InsteadA hand sink is only for hands; using it for anything else blocks it and makes people stop treating it as the place to wash.

Practice problems

Work each problem on paper first, then reveal the answer to check.

  1. A server has a small cut on her finger and is scheduled to cut fruit for the bar. What should happen?

    Show answer

    She covers the cut with a clean waterproof bandage and wears a single-use glove over it; if the cut is infected or cannot be covered, she does other work until it heals.

  2. Why must the paper towel be used to turn off the tap?

    Show answer

    The tap was turned on with dirty hands; touching it again with clean hands would put germs back on them.

  3. A line cook says his roommate has been diagnosed with norovirus but he feels fine. What does the Food Code expect?

    Show answer

    Living with someone diagnosed with a Big 6 illness must be reported. In a restaurant that does not serve a highly susceptible population the Food Code does not require restriction, but the person in charge reviews handwashing and no bare-hand contact with him and watches for symptoms.
