Mercadona is in the middle of a public relations disaster after its ‘Compy’ own label dog food brand was linked to the deaths of several pets across Spain, after having caused kidney failure in the animals. . The deaths were initially recorded by pet owners in Andalucia, Murcia and Alicante, but new reports have claimed that similar cases have been found along the Costa del Sol. Several pet owners insisted that the deaths were caused after their pets ate the own label product, and following intense pressure, Mercadona has removed two variants of the ‘Compy’ range from select stores. The chain said it is now studying whether there indeed is a connection between the product and the deaths. It would not comment on whether the problem was caused by a recent shift in packaging of the product from tins to cartons. Mercadona added: “At this stage we have only removed the product as a precaution and we are waiting for the results of the analysis. We do not know with any certainty if the food is to blame”.
