Cotton Mill Fever

Cotton mill fever is a short-lasting, flu-like illness that happens after breathing a large amount of cotton dust, usually inside textile mills. People feel feverish, chilled, achy, tired, and short of breath. The dust often contains tiny bits of plant material and endotoxin (a toxin from certain bacteria that live on cotton). This toxin can quickly irritate the airways and the whole body. Symptoms usually start during a work shift with heavy dust exposure and often ease after leaving the mill. Many experts see cotton mill fever as an acute reaction to cotton dust and its endotoxin—part of the same family of problems as byssinosis (“brown lung”), which is the longer-term airways disease from repeated cotton dust exposure. Encyclopedia Britannica+3NCBI+3JAMA Network+3

Cotton mill fever is a lung disease that happens after breathing cotton dust for months or years, especially in spinning, carding, and weaving rooms. On the first day back to work—often Monday—people can feel tightness in the chest, cough, wheeze, or feel short of breath. Over time, if the dust exposure continues, the problem can look like a mix of asthma and COPD. The main cause is breathing cotton dust that carries tiny plant particles and bacterial pieces (endotoxin) that inflame and narrow the airways. The safest and most important treatment is reducing exposure at work (engineering controls, ventilation, wet methods, and certified respirators), and moving the worker to cleaner areas if needed. Bronchodilator inhalers and inhaled steroids, used for asthma/COPD, can help symptoms. Quitting smoking is strongly advised. MSD Manuals+4blogs.cdc.gov+4OSHA+4

Other names

• Mill fever / Monday fever — older terms used by mill workers and doctors; “Monday” reflects symptoms being worse on the first workday after a break. NCBI+1

• Byssinosis / brown lung / cotton worker’s lung — the chronic airways disease from repeated exposure to cotton (and similar) dust; related to, but not the same as, the brief feverish attacks of cotton mill fever. NCBI+2Wikipedia+2

Types

1. Acute cotton mill fever (endotoxin burst)
   A sudden, flu-like reaction within hours of heavy cotton dust exposure. People develop fever, chills, cough, chest tightness, and feel unwell. It may recur with new high exposures and often settles after leaving the dusty area. JAMA Network+1

2. Byssinosis-pattern airway disease (short-term reversible)
   Some workers mainly get chest tightness, cough, and breathlessness that are worse on the first workday and improve by mid-week or on days off. This pattern reflects airway narrowing that is partly reversible early on. NCBI+1

3. Byssinosis-pattern airway disease (chronic/fixed obstruction)
   With years of exposure, some people develop ongoing cough, wheeze, and fixed airflow limitation (similar to COPD). Even on weekends or after leaving the job, breathing may remain limited. blogs.cdc.gov

Note: Many clinicians use “mill fever” for the acute, feverish attacks and “byssinosis” for the longer-term airway disease; both relate to cotton dust and its endotoxin. NCBI+1

Causes

1. Breathing cotton dust
   Cotton processing releases fine plant dust that reaches deep into the lungs and can trigger illness. NCBI

2. Bacterial endotoxin on cotton
   Cotton can carry gram-negative bacterial endotoxin, which provokes a strong body-wide inflammatory response and fever. Encyclopedia Britannica+1

3. Heavily contaminated lots of cotton
   Bales stored damp or contaminated can have higher endotoxin loads, raising risk during opening and carding. CDC Stacks

4. High-dust work areas (opening, carding, blowing)
   These early processing steps create the greatest dust clouds and exposures. CDC Stacks

5. Poor ventilation or inadequate dust control
   Insufficient local exhaust or filtration lets dust accumulate in the breathing zone. blogs.cdc.gov

6. No or poor-fitting respiratory protection
   Not wearing well-fitted masks/respirators leaves lungs unprotected in dusty rooms. blogs.cdc.gov

7. Return after time off (the “Monday effect”)
   Symptoms tend to be strongest on the first day back after a weekend or leave, likely from a fresh high exposure without recent adaptation. NCBI

8. Long work shifts or overtime in dusty rooms
   Longer exposure time increases the total dose inhaled in a day. CDC Stacks

9. Humidity and heat
   Warm, humid air can keep dust suspended and may worsen discomfort and breathing symptoms. (Inference consistent with dust behavior and mill studies.) CDC Stacks

10. Mixing of plant fibers (cotton, flax, hemp, jute)
    Similar dusts from other plant fibers can contribute to the same problem. CDC Stacks

11. Cigarette smoking
    Smokers are more likely to have airway symptoms and chronic problems when exposed to cotton dust. Wikipedia

12. Pre-existing asthma or COPD
    Existing airway disease makes people more reactive to mill dust. blogs.cdc.gov

13. High-speed machinery without proper enclosure
    Faster machines can aerosolize more dust if not enclosed or vented well. CDC Stacks

14. Infrequent housekeeping and dust buildup
    Settled dust can be re-aerosolized by foot traffic or fans. CDC Stacks

15. Handling “dirty cotton” (leaf, bract, stem fragments)
    Non-fiber plant fragments carry more endotoxin and irritants. CDC Stacks

16. Lack of engineering controls (e.g., wet methods, LEV)
    Not using water sprays or local exhaust ventilation raises airborne dust. blogs.cdc.gov

17. Work at bale opening or waste handling
    These tasks disturb older, possibly damp cotton with higher microbial growth. CDC Stacks

18. Previous severe reaction (sensitization)
    People who already reacted may respond faster or more strongly to new exposures. (Clinical pattern described in case reports.) JAMA Network

19. Organic Dust Toxic Syndrome mechanisms
    A very high short-term exposure to contaminated dust can trigger a whole-body toxic response similar to ODTS, with fever and aches. Health & Human Services+1

20. Insufficient medical surveillance and monitoring
    Without routine lung function checks, exposure can continue until symptoms become obvious. blogs.cdc.gov

Diagnostic tests

A) Physical examination

1. Vital signs
   The clinician checks temperature, heart rate, breathing rate, and oxygen level. Fever and a faster pulse support cotton mill fever after exposure. JAMA Network

2. Lung listening (auscultation)
   Wheezes or prolonged exhalation suggest narrowed airways from dust irritation. blogs.cdc.gov

3. Observation of breathing effort
   Use of neck or chest muscles, fast breathing, or difficulty speaking full sentences shows respiratory strain. (Standard respiratory exam practice; consistent with byssinosis physiology.) blogs.cdc.gov

4. Pulse oximetry at rest
   A finger sensor estimates oxygen saturation; a drop suggests significant airway or gas-exchange strain. (Routine respiratory assessment; aligns with byssinosis care.) blogs.cdc.gov

5. Inspection of eyes/nose/throat
   Irritated conjunctiva or nasal mucosa supports a dust-related exposure. CDC Stacks

B) Manual/bedside functional checks

6. Peak flow diary across the work week
   Simple handheld peak-flow readings before and after shifts can show the “Monday drop” and improvement by mid-week or days off. NCBI

7. Pre-/post-shift peak flow comparison
   A same-day fall after a dusty shift points to work-related airway narrowing. (Standard occupational asthma/byssinosis practice.) blogs.cdc.gov

8. Trial of short-acting bronchodilator with symptom tracking
   If symptoms and peak flow improve after an inhaler, it supports reversible airway narrowing from dust. (Common clinical approach with byssinosis-like disease.) blogs.cdc.gov

9. Six-minute walk test (simple endurance check)
   Measures how far a person can walk and whether oxygen levels drop with activity during recovery from an acute episode. (General respiratory functional assessment.) blogs.cdc.gov

    Often rise with acute endotoxin-related illness and help track recovery. (Broad inflammatory response markers; consistent with ODTS physiology.) Health & Human Services

12. Sputum culture (if productive cough)
    Helps exclude bacterial pneumonia; cotton mill fever itself is toxic-inflammatory, not a classic infection. JAMA Network

13. Arterial blood gas (ABG) in severe breathlessness
    Measures oxygen and carbon dioxide; used when oxygen levels look low or symptoms are severe. (Standard respiratory care.) blogs.cdc.gov

14. Endotoxin testing of workplace dust (LAL assay)
    An industrial hygiene test of dust samples for endotoxin; supports the exposure link. cotton.org

D) Device-based pulmonary function tests

15. Spirometry (FEV₁, FVC, FEV₁/FVC)
    Looks for airway obstruction; values can drop after a dusty shift and improve away from work. NCBI

16. Serial spirometry across the week
    Demonstrates the “Monday effect” and recovery trend; helpful in work-related airway disease. NCBI

17. Bronchodilator responsiveness
    Checking FEV₁ before and after inhaled bronchodilator shows how reversible the narrowing is. blogs.cdc.gov

18. Methacholine challenge or impulse oscillometry (when needed)
    Assesses airway hyper-reactivity when basic tests are inconclusive. (Used in occupational asthma/byssinosis assessments.) NCBI

E) Imaging

19. Chest X-ray
    Often normal in simple cotton mill fever; may show hyperinflation or signs of another illness that needs treatment. NCBI

20. High-resolution CT (HRCT)
    Used when symptoms persist; can show air-trapping or small-airway disease in chronic byssinosis. Eduvest

Non-pharmacological treatments

1) Engineering controls (local exhaust & enclosure).
Description: Install hoods, ducts, and enclosed carding/opening machines to capture dust at the source; maintain filters and ensure adequate airflow.

Surgeries

There are no surgeries for byssinosis itself. Rarely, if chronic disease progresses to severe emphysema/COPD despite exposure elimination and optimized therapy, specialized procedures may be considered:

1. Lung volume reduction surgery – removes badly damaged emphysematous lung to improve mechanics in selected COPD; done only after strict criteria. Why done: Improve dyspnea/exercise capacity. MSD Manuals

2. Endobronchial valves (bronchoscopic LVRS) – minimally invasive option for selected emphysema patterns. Why done: Symptom relief. MSD Manuals

3. Bullectomy – for giant bullae causing compression, in carefully chosen COPD patients. Why done: Improve ventilation. MSD Manuals

4. Lung transplantation – only for end-stage disease after all options fail. Why done: Survival and quality of life in selected candidates. MSD Manuals

5. Tracheostomy for chronic ventilatory failure (rare) – palliative airway access in end-stage cases. Why done: Long-term ventilatory support. MSD Manuals

When to see a doctor

• If you have chest tightness, wheeze, or shortness of breath that starts during your shift or worsens on Mondays.
• If your rescue inhaler is needed more often or works less well.
• If you have night symptoms, low oxygen readings, or fainting.
• If symptoms continue on days off—this may mean chronic damage.
• If you smoke and work with cotton dust—ask for help quitting.
These visits should include a full occupational history, spirometry (ideally pre/post shift), and discussion about exposure reduction or job changes. ijomeh.eu+1

FAQs

1) Is cotton mill fever the same as byssinosis?
Yes. It is the historic name for byssinosis, an occupational airways disease from cotton dust exposure. Wikipedia

2) Why are symptoms worse on Mondays?
A break away from dust reduces airway reactivity; returning after rest triggers tightness within hours—the “Monday” pattern. ijomeh.eu

3) Does endotoxin cause the problem?
Endotoxin in cotton dust activates lung immune cells and can provoke airflow drops; it’s a major suspected driver, though not the only factor. Wiley Online Library+1

4) Can byssinosis become permanent?
Yes—long exposure can lead to persistent obstruction resembling asthma/COPD. Reducing exposure early is vital. MSD Manuals

5) Are there specific FDA-approved drugs for byssinosis?
No. We use standard asthma/COPD medicines for symptoms and control; exposure control remains the key. MSD Manuals

6) Can I just use an inhaler and keep my job?
Inhalers help, but engineering controls and lower dust are essential; otherwise the disease may progress. OSHA+1

7) What’s the most important workplace step?
Controlling dust with ventilation, wet methods, and enclosure—plus medical surveillance. OSHA+1

8) Do respirators replace ventilation?
No. Respirators are a back-up when controls can’t keep levels low; they must be fit-tested. MSD Manuals

9) How is the diagnosis made?
Symptoms tied to work + pre/post-shift lung function drop + exposure history; other lung diseases are ruled out. Wikipedia

10) Will steroids cure it?
Inhaled or short oral steroids can reduce inflammation and symptoms, but they do not remove the cause—dust exposure. FDA Access Data+1

11) Are supplements helpful?
