el besteo

Spanish to English Other Manufacturing

Source country: Mexico. The term "besteo" appears in text on the preparation of pet food. The full sentence reads:

"..desde la recepción de materia prima hasta la selección o clasificación de productos secos, el Besteo, Empaque y Despacho de Producto, SOP de trazabilidad y Recall".

Could be a spelling mistake, but does anyone know what this is or could be? Kind regards. Sian.
