Understanding the types of biological hazards, the health effects they can cause, and the necessary preventive measures are essential to minimize risks. Biological hazards, commonly referred to as biohazards, are a significant concern in various industries. These hazards can pose serious threats to worker health and safety, particularly in environments where exposure to harmful microorganisms is prevalent.
The recent COVID-19 outbreaks in the US, for example, had a significant impact on essential workplaces, such as meatpacking plants, healthcare facilities, and warehouses. For instance, food processing plants in the Midwest saw large outbreaks due to close working conditions and challenges in maintaining physical distancing.
These outbreaks resulted in temporary plant closures, disrupting supply chains and putting workers at heightened risk. This case shows the significant risks biohazards pose to worker safety and health.

What Are Biological Hazards?
A biological hazard is any biological substance that has the potential to harm humans, animals, or the environment. Some biological hazard examples are bacteria, viruses, fungi, and parasites that can cause infections, allergic reactions, or diseases.
Workplaces such as hospitals, laboratories, food processing plants, and agricultural sites are particularly prone to these hazards. Controlling exposure and contamination to these harmful substances is essential for maintaining a safe working environment.
5 Types of Biological Hazards
1. Bacterial Hazards
Bacteria are single-celled microorganisms that can be either beneficial or harmful to humans. In workplace environments, bacterial hazards arise when disease-causing bacteria are present. Common examples of harmful bacteria include Legionella, which leads to Legionnaires' disease, Escherichia coli (E. coli), and Staphylococcus aureus.
2. Viral Hazards
Viruses are biological agents much smaller than bacteria and can only replicate within the living cells of a host. Viral hazards in workplaces are particularly dangerous because they can spread quickly through the air, on surfaces, or through direct contact with infected individuals.
Common viral hazards that workers may encounter include influenza, hepatitis (hepatitis B), human immunodeficiency virus, and the highly contagious SARS-CoV-2 (COVID-19). These viruses are transmitted through airborne droplets from coughing or sneezing, contact with contaminated surfaces, human blood and body fluids, or close interaction with infected individuals and animals.
3. Fungal Hazards
Fungi are biological agents that thrive in moist, warm environments. While some are harmless, others can pose serious health risks. Fungal hazards in the workplace often arise from exposure to airborne spores or mold. Harmful fungi such as Aspergillus can lead to lung infections.
Workplaces prone to fungal hazards include damp or poorly ventilated environments, construction sites with high humidity, and buildings affected by water damage. Without proper ventilation and regular cleaning, these environments can become breeding grounds for fungi.
4. Parasitic Hazards
Parasites are organisms that live in or on a host and can cause a variety of diseases in humans. Parasitic hazards are commonly found in industries that handle contaminated water, food, or animals. Notable examples include Giardia, a parasite found in contaminated water.
The sources of parasitic hazards include water or food that has been contaminated, poor hygiene in food preparation areas, and direct contact with infected animals, animal products, or soil. Inadequate sanitation practices greatly increase the risk of parasitic infections and serious diseases in the workplace.
5. Zoonotic Hazards
Zoonotic hazards is a biological hazard that are transmitted from animals to humans. Workers in agriculture, veterinary care, and food processing industries are at particularly high risk for zoonotic infections, such as avian flu, rabies, Q fever and other animal diseases.
These diseases are commonly spread through contact with infected animals or animal products, the handling of contaminated tools or equipment, and exposure to aerosols and animal waste such as bird droppings.
Effects of Biological Hazards on Health
Biological hazards pose a threat to every workplace. Exposure to biological hazards can lead to a wide range of health issues. These issues to human health vary from mild discomfort to serious illness or long-term conditions. Some of the common health effects include:
- Respiratory infections: Airborne bacteria, fungi, and viruses can cause lung infections, including conditions such as pneumonia and Mycobacterium tuberculosis.
- Gastrointestinal issues: Ingesting food or water contaminated by parasites or bacteria, such as Salmonella or Giardia, can lead to food poisoning and foodborne illnesses, causing nausea, vomiting, and diarrhea.
- Skin infections: Direct contact with bacteria like Staphylococcus or fungi like Candida, can result in skin infections or rashes.
- Chronic illnesses: Prolonged exposure may lead to chronic diseases such as asthma, allergies, or even long-term lung damage due to repeated inhalation of harmful spores or pathogens.
Workers who are already immunocompromised or have preexisting health conditions and life-threatening disease may experience more severe health consequences from exposure.
Preventive Measures for Biological Agents
To effectively reduce the risks associated with different types of biological hazards, organizations must implement comprehensive safety protocols and disease control measures. These measures effectively manage biological hazards and ensure the protection of workers and minimize potential exposure to harmful biological agents.
Risk Assessment
The first and most critical step in managing these hazards is conducting a thorough risk assessment. Employers need to identify all potential sources of exposure within the workplace, evaluate the likelihood of contact, and assess the biohazard safety levels. This process helps in developing tailored control measures covering biological hazards present in a particular environment.
Workplace Hygiene
Maintaining high standards of workplace hygiene is essential in minimizing the biohazard level in any occupational setting. Regular cleaning and disinfecting of work surfaces and equipment are crucial to eliminating harmful microorganisms.
Additionally, proper waste disposal practices ensure that contaminated materials, such as microbiological waste, are handled and disposed of safely. The availability of handwashing stations and hand sanitizers further promotes good hygiene, reducing the risk of transmission.
Personal Protective Equipment (PPE)
Workers exposed to biohards must observe extreme caution. Providing appropriate personal protective equipment (PPE) is a key factor in protecting employees from exposure to any biological hazard. The type of PPE required depends on the nature of the hazard.
Gloves are used to prevent skin contact. Meanwhile, masks and respirators protect workers from inhaling airborne pathogens. In high-risk environments, additional PPE such as gowns, face shields, or goggles may be necessary to protect against contamination.
Employee Training
Employee training plays a vital role in reducing exposure to these hazards. Workers must be adequately trained on the risks and the correct safety protocols to follow. Training programs should cover the proper use of PPE, the safe handling of contaminated materials, and the importance of hygiene practices to prevent the spread of infectious agents.
Emergency Preparedness
Having a robust emergency response plan is essential for dealing with biological hazard incidents. This plan should outline clear procedures for isolating affected areas to prevent further contamination. Immediate first-aid measures, such as the use of eyewash stations, should be in place to assist workers who have been exposed to biological materials. Additionally, communication protocols must be established to notify health authorities and relevant personnel in the event of a serious exposure incident.
