Biohazards parasites

Additional considerations include vaccinations of investigators against rabies or tuberculosis, especially when working with some mammals and their parasites. These preventative measures are needed to protect the researcher. Animal necropsy should include protective clothing and the containment of possible biohazards, in order to avoid contracting diseases such as psittacosis, erysipelas, rickettsial infections, and brucellosis.5 The... 

However, dangers from biohazards remain. There are many current examples, such as bacteria in hot tubs and spas. There are parasitic infections from raw fish and meat and from untreated drinking water. There are dangers from molds in food, water systems, and damp parts of buildings. There are exposures to insects, plants, animals, and birds that are biohazard carriers. Humans may be biohazard carriers. There are biohazards in biological laboratories, on farms, and in food processing plants. Whether one is a consumer or worker, there are many activities that have biohazards. 

Biohazards are biological hazards from plants, animals, insects, or their products that may be infectious, toxic or allergenic. Agents are bacteria, viruses, fungi, rickettsia, or parasites. 

The classification of biological risk is defined by Ordinance 3.214/78 of the Ministry of Labor and Employment, in its regulatory standards and job security (Brasil, 2002). Biohazards are represented by bacteria, fungi, parasites, viruses, among others. It is known that occupational exposure to potentially contaminated biological materials constitute a serious risk to health professionals in their workplaces. 

According to the AIHA Biohazards Committee, a biohazardous agent is one that is biological in nature, capable of self-repHcation and has the capacity to produce deleterious effects upon other biological organisms, particularly humans (AIHA 1986). The four broad classes of microorganisms that can interact with humans are bacteria, fungi, viruses, and protozoan parasites.
