Recent consumer concerns about food safety and the impacts of contamination and environmental degradation contribute to the increased demand for organic foods, among which milk and dairy products are among the main products of commercial interest. The value added of the organic product is two to three times higher than that of conventional milk and derived products, a fact that has motivated the migration of traditional producers to the organic modality. However, the production of organic milk in Brazil is considered insipient, and the scarcity of information on the sector is one of the contributing factors for this scenario. Under the legislation governing organic production, sanitary control of dairy herds should be based on the use of homeopathic products, herbal products and acupuncture. However, little is known about the strategies actually used by farmers to circumvent the health problems, or even if they are effective, which justifies the research with the production units to remedy these knowledge gaps on organic livestock. Therefore, the objective of this project is to carry out a survey of the diseases that affect the animals in different stages of breeding and the subsequent treatments used in organic dairy herds in the mountainous and southern regions of the state of Rio de Janeiro and to evaluate the milk quality through the parameters: Somatic Cell Count (SCC) and Total Bacterial Count in Colony Forming Units (CFU). This project will be submitted to the Ethics Committee on the Use of Animals of the Veterinary Institute of the Universidade Federal Rural do Rio de Janeiro (CEUA / IV / UFRRJ). The study will be carried out on properties certified or undergoing certification for the production of organic milk located in the mountainous and southern regions of the state of Rio de Janeiro. The interviews will take place from December 2018 to July 2019. They will be carried out semi-structured through the application of a questionnaire with questions previously elaborated addressing in blocks the following aspects: information about the owner and the property; characterization of the organic milk activity in the property; characteristics of production; characteristics of the herd; nutritional management and health aspects of the herd. The information obtained will be checked with the in situ observation of the property, the herd and the management. In addition, a milk sample from each property will be collected on the day of the interview from the cooling tank or brass for analysis of the indicators Somatic Cell Count (SCC cells / mL) and Total Bacterial Count in Colony Forming Units (CFU / mL) in order to evaluate the health conditions of the herd and the management of milking. These samples will be sent to the Laboratory of the Brazilian Milk Quality Network (RBQL) of Embrapa Dairy Cattle located in Juiz de Fora, MG. Analyzes of interview data will be conducted qualitatively. While the values obtained by the analysis of the milk related to CFU (x106 / mL) and CCS (x103 / mL) will be compared and discussed with those allowed in the current milk quality control legislation. The percentage values will be submitted to non-parametric analysis and the means compared by the chi-square test, 5% probability
