Greenpeace is in front of the Lidl supermarket in Cologne with a three-meter-high pork chop and an information stand. The activists offer consumers the opportunity to test their bought meat under black light for residue of antibiotics. The stand also gives information on the negative consequences of the use of antibiotics in factory farming.
Antibiotics residue is deposited in the bone structure of the pigs that were treated, which can be still made visible in the cut meat under black light.
Due to an increasing use of antibiotics in factory farming, the number of multi-resistent germs in farms and the environment is also increasing. This results in common antibiotics becoming ineffective.
Discount supermarkets such as Lidl use their low-cost policy to force factory farms to produce low-cost meat at the high cost of animals and the environment.

Greenpeace reist durch Deutschland mit einem drei mal drei Meter großen Kotelett und umfangreichen Informationen ueber die schaedlichen Folgen der Massentierhaltung an einer Filiale der Discount-Kette Lidl in Koeln.
Rueckstaende von Antibiotika lagern sich in den Knochen von Schweinen ab und werden unter einer Schwarzlichtlampe sichtbar. Verbraucher koennen sich am Greenpeace-Stand selbst davon ueberzeugen.
Weil in der Massentierhaltung zu viele Antibiotika eingesetzt werden, vermehren sich immer mehr multiresistente Keime in den Staellen und in der Umwelt, die gaengige Antibiotika wirkungslos machen.
