Which one of the following occupational diseases occurs due to sugarcane dust?

Appeared in: ESIC Nursing Officer-7July 2024

Explanation

Bagassosis is an occupational lung disease, specifically a type of hypersensitivity pneumonitis.
It is caused by inhaling dust from bagasse, which is the fibrous residue left after crushing sugarcane.
The causative agent is often a thermophilic actinomycete, Thermoactinomyces sacchari, found in the bagasse dust.
Symptoms include breathlessness, cough, fever, and in chronic cases, can lead to lung fibrosis.

Option A: Anthracosis, also known as coal worker's pneumoconiosis, is caused by the inhalation of coal dust, not sugarcane dust.
Option B: Silicosis is caused by inhaling crystalline silica dust, which is found in materials like sand, quartz, and granite.
Option C: Farmer's lung is another form of hypersensitivity pneumonitis, but it is caused by inhaling spores from moldy hay, straw, or grain.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Occupational lung diseases and their causative agents as background academic context rather than a clinical decision trigger.
Nurses in occupational health settings are key to primary prevention. This includes educating workers on the importance of personal protective equipment (PPE), such as fit-tested respirators, to minimize dust inhalation.
Secondary prevention involves health surveillance. Nurses may perform or assist with regular spirometry tests for workers in high-risk industries to detect early changes in lung function.
What if? If a worker from a cardboard manufacturing plant presents with cough and breathlessness, the nurse should have a high index of suspicion for Bagassosis. Bagasse is not only a byproduct of sugar mills but is also used as a raw material for paper and cardboard, making those workers also at risk.

How to Approach the Question

First, identify the core subject of the question, which is an 'occupational disease'.
Next, pinpoint the specific causative agent mentioned: 'sugarcane dust'.
Access your knowledge base of occupational health to link the agent to the disease. The term for sugarcane residue is 'bagasse'.
Evaluate the options. 'Bagassosis' directly relates to 'bagasse'.
Confirm your choice by mentally eliminating the other options. Anthracosis is from coal, Silicosis is from silica, and Farmer's lung is from moldy hay. This confirms Bagassosis is the only correct option.
