What was the result of the determination of the Most Probable Number (MPN) of thermotolerant coliforms at 45°C?
The result obtained was < 3.0 MPN/g.
The ANVISA Resolution - RDC No. 12, of January 2, 2001, allows 10³ Estaf.coag.positiva/g.
All dilutions of the inoculated tubes showed negative characteristics for the presuntive test.
a) Only I is correct.
b) I and II are correct.
c) I and III are correct.
d) I, II and III are correct.

A resposta correta é a alternativa "a) Only I is correct." A determinação do Número Mais Provável (NMP) de coliformes termotolerantes a 45°C foi menor que 3,0 NMP/g, o que indica que a quantidade de coliformes termotolerantes na amostra é menor que o limite permitido pela ANVISA, que é de 10³ Estaf.coag.positiva/g. Além disso, todas as diluições dos tubos inoculados apresentaram características negativas para o teste presuntivo.
