What are foodborne zoonotic pathogens Why are they important for public health
My name is Pia and I am a scientistin the European Food Safety Authority. I am going to tell you what arethe foodborne zoonotic pathogens and why they are important topublic health and to humans. And first of all this term zoonotic, it comes from the Latin term zoonosis which means diseases and infectionswhich are transmissible between animals and humans,and quite often these infections are transmitted throughcontaminated food stuffs. The most important foodbornepathogens in Europe are bacteria
such as Salmonella, Campylobacterand certain types of Escherichia coli, and these bacteria typicallycause diarrhoea in humans but also sometimesmore serious symptoms. And then we still have somefoodborne parasites in the EU such as Trichinella and then ofcourse there are also some other pathogens. Animals, such as pigs, cattle, andpoultry they quite often carry these food borne pathogens in theirgut content, or skin or even in their muscles, but in most cases thesepathogens do not cause any disease in animals.
But when food from these types ofinfected animals is being produced, the food can become contaminated withthese pathogens and then when humans eat this type of contaminated food theycan get infected and get the disease. These foodborne zoonoticpathogens are important in Europe and that is because these pathogens causeover three hundred thousand reported human cases in the European Unioneach year, and most likely there is even more cases because of the commonunderreporting. So we have actually overtwo hundred thousand
reported Campylobacterosiscases in humans each year in the European Union and around one hundred thousand reported Salmonellosis cases in humans and for the otherpathogens is of course less. Thus it is important to prevent thesediseases from occurring and in fact the European Union has already issuedlegislation which aims to reduce these pathogens in animals and alsofurther up in the food chain. And these methods have alreadyresulted in the reduction of human Salmonellosis cases in theEuropean Union and these cases
have actually dropped by almosthalf in the last six years. But you can also takesome actions by yourself to avoid these diseases, and forthat purpose it is important always to cook raw meatand raw eggs thoroughly and also have goodkitchen hygiene at home.
How to prevent the spread of resistant bacteria
SILENCE TRANQUIL MUSIC VOICEOVER:Bacteria can make you ill. Some bacteriaare resistant, in which case treatment with antibioticshas a limited effect, to none at all. This can cause you to become very ill,and possibly even die. You can also carry bacteriawithout becoming immediately ill, in which caseyou can still spread them.
The spread of resistant bacteriais dangerous, especially for peoplewith poor health. You can be contaminatedwith a resistant bacterium, for example, as a result ofadmission to a nursing home or , admission to a abroad,or through contact with farm animals. This is why proper hygiene,such as washing your hands, is important. If someone is contaminatedwith a resistant bacterium, it's important to become aware of thisas soon as possible
in order to preventfurther spreading. This is why s enquire aboutpossible exposure to resistant bacteria, whether you have been treatedin other nursing homes or s, in a foreign , or if you have hadany contact with farm animals. Everyone should be attentive to this,so we can minimise the risk.
