A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other living beings. [a]
The third type of carcinogen is biological which highlights infections that can be caused from viruses, bacteria, or parasites. [2] There are many risk factors when it comes to the human body and carcinogens, which is why it is so important that the proper approach is used when attempting to reduce expose to cancer causing carcinogens.
Environmental hazards can be categorized in many different ways. One of them is — chemical, physical, biological, and psychological. Chemical hazards are substances that can cause harm or damage to humans, animals, or the environment. They can be in the form of solids, liquids, gases, mists, dusts, fumes, and vapors.
Food safety (or food hygiene) is used as a scientific method/discipline describing handling, preparation, and storage of food in ways that prevent foodborne illness.The occurrence of two or more cases of a similar illness resulting from the ingestion of a common food is known as a food-borne disease outbreak.
