Melanosis uberis en un cerdo
El estudio histopatológico muestra el depósito de pigmento de color marronáceo-negruzco (melanina) alrededor de los conductos de glándula mamaria y también de vasos sanguíneos. Esta condición se conoce como melanosis uberis y está descrita en cerdos y en osos. Se trata probablemente de un defecto congénito.
Punteado negro la grasa subcutánea de la región ventral.
A mayores aumentos se puede observar que las manchas negras muestran un patrón filamentoso, siguiendo conductos mamarios y/o vasos.
Melanocitos en el espacio subepitelial, cargados de pigmento (cabezas de flecha). Macrófagos cargados de pigmento alrededor de los vasos sanguíneos (fecha).

but is this edible? that’s all I want to know.
Yes, it is edible. Melanosis is not of public health concern (just cells with black pigment) but, when present, the carcass might be condemned due to organoleptic alteration.
Is there any way I can upload a picture of what I think might be malanosis uberis to add to this page?!
Thanks for your comment!
You may the file to suport.escorxadors@irta.cat and i’ll ask the IT guys to post it near your comment.

My client also had this problem and has approved by VLDL of Vet. Chulalongkorn University As the accumulation of melanin pigment in fat layer of pig’s belly (around mammary gland – bacon part). More high frequency rate of gilt than barrow or entire pig.http://www.isranews.org/images/2014/thaireform/CU2.jpg

Sometimes seen in entirely black pigs. Some times even melanin in lymphnodes and organs.

Is it possibly any way that it relates to eating canola meal? I was asked this question by slaughter house officials at WPX 3 years ago.

Check for tannin in raw materials?

Is this simply immature/nongravid mammary tissue?
Quin va ser el dictàmen en realció a l’aptitud o no per al consum humà?
Gràcies
El dictamen va ser decomís parcial (espurg) de la zona afectada i aptitud de la resta de la canal.
