Listeria is a food-borne bacterial illness and the bacteria is found in soil, water, poultry, cattle, sheep goats, rabbits, guinea pigs and other species. Corgis can be infected with Listeria by the same source as human exposure including infected meats and dairy products as well as contaminated dog food, water and garbage. DOGS FED RAW MEAT DIETS (INCL RAW BONES) ARE AT MUCH HIGHER RISK FOR LISTERIA INFECTION AS WELL AS SALMONELLA. Listeria is killed by pasteurisation and cooking. Other food which could be infected include: raw vegetables that have been contaminated from the soil from contaminated manure used to fertilise the soil, deli-prepared salads, infected animal meats such as from hot dogs, sift cheeses such as feta, brie, camembert, blue vein etc and smoked seafood. Corgis should always be provided with fresh, clean water in clean water bowls.
