Brazilian legislation, as determined by Normative Instruction 76 (IN 76), determines that properties must present average monthly SCC results below 500 x 10³ cells/ml of milk, a value that represents balance between animal health and food safety for consumers. However, it is known that in practice farmers still face major challenges to achieve this goal.
In Figure 1, it is possible to identify that only 11% of the 550 properties analyzed by the Department of Intelligence of Labor Rural obtained average annual SCC lower than 200 x10³ cells/ml, reference value used to consider a herd as healthy. And 54% of these properties have average annual SCC lower than 400 x 10³ cells/ml, a value still considered acceptable for herd health. This information shows that although the legislation already requires SCC values lower than 500 x 10³ cells/ml, this is still a challenge in most properties, and it is up to us, professionals and farmers in the dairy chain, to work to control SCC values at those properties.
