Este estudo objetivou avaliar a qualidade de leite cru em trinta amostras colhidas de tanques de expansão no estado de Goiás, num volume de 1.000 mL. Para tanto, realizou-se contagem bacteriana total (CBT) por citometria de fluxo, bem como se procedeu a pesquisas de resíduos de antimicrobianos pelo kit Delvotest® SP e de fraude por adição de água oxigenada, formol, bicarbonato de sódio e hidróxido de sódio. Em 100% das amostras notou-se ausência de resíduos de antimicrobianos. Além disso, os testes físico-químicos não indicaram a presença de água oxigenada, formol, bicarbonato de sódio e hidróxido de sódio. Do total dos tanques de expansão, 30% (9/30) apresentaram CBT >106 UFC/mL, em 46,67% (14/30) a CBT estava entre 105 e 106 UFC/mL e em 23,33% (7/30) havia CBT 106 UFC/mL, 100% eram de uso coletivo e mostraram valores de CBT significativamente maiores (PPALAVRAS-CHAVES: Leite cru, qualidade, resíduos, UFC. This research aimed to evaluated the raw milk quality in samples obtained from bulk tanks in the Goiás State. Thirty raw milk samples of 1000 mL were harvest. It was performed the following analyses: total bacterial count (TBC) by Flow Citometry, search for the presence of residues of antimicrobial agents by the Delvotest® SP kit and investigation for the fraud by adding to milk the following substances: hydrogen peroxide, formaldehyde, sodium bicarbonate and sodium hydroxide. It was not found any residues of antimicrobial agents in all (100%) samples. Physicochemical test also showed the absence of hydrogen peroxide, formaldehyde, sodium bicarbonate and sodium hydroxide in milk. About TBC, it was observed that 30% (9/30) of bulk tanks showed TBC>106 CFU/mL, in 46.67% (14/30) the TBC was between 105 to 106 CFU/mL and 23.33% (7/30) showed TBC 106 CFU/mL, 100% were available for common utilization and had significantly higher values for TBC (PKEY WORDS: CFU, raw milk, quality, residues. |
