Adequação da contagem de células somáticas e da contagem bacteriana total em leite cru refrigerado aos parâmetros da legislação

Abstract

The aim of this work was to adequate raw refrigerated milk quality of five dairy farms to microbiological and somatic cell count (SCC) standards established by Paraná state legislation. The dairy farms were monitored during seven months after the implementation of good milking practices and recommendations regarding mastitis treatment, and milking equipment maintenance and hygiene. Before the adoption of recommendations, the average total bacterial count (TBC) was 1.36 x 106 CFU/mL and average SCC was 1.87 x 106/mL. All farms reached established standards for TBC, originating an average reduction of 93.4%. Average SCC reduction was 74.3%. Only three farms reached established values for SCC. The remaining reached values near the limits. The suitability of TBC and SCC produced an increase in the monthly income due to payment quality reward of the dairy product, between R$nd R$828.00, according to each farm production.
