Resumen

Objective: to determine the nutritional and physicochemical quality, and the presence
of aflatoxins in raw milk, as well as risk factors for developing mastitis in 20 family farms
in the region of Texcoco, Mexico.
Methods: MilkoSCan FT1 was used for nutritional and physicochemical analysis of
milk. Somatic cells were quantified and the cow’s health status was tested using
Somaticell; furthermore, the presence of Aflatoxin M1 was determined using lateral flow
immunochromatography.
Results: the milk evaluated in this study reported normal nutritional values according to
NMX-F-700-COFOCALEC-2012, which guarantees its quality for human consumption.
The pH ranged from 5.0 to 8.4, which indicates deficient temperature control in some
farms, leading to problems with acidity. The logistical analysis showed that adequate
udder cleaning during milking is important to avoid it being a risk factor for an increase
in somatic cells and degree of mastitis, although not the milking technique or teat
sealing. The presence of aflatoxin AFM1 was not reported in raw milk.
Study implications: the Somaticell® technique renders a qualitative and efficient
diagnosis of clinical mastitis.


Conclusions: raw milk quality from this region guarantees consumers with a safe and
apt product for human consumption or transformation into dairy byproducts.
