The massive increase in the prevalence of MRSA in Denmark is also affecting Swedish consumers. A study carried out by Swedish newspaper Dagens Nyheter in tandem with Sweden’s National Veterinary Institute (Statens veterinärmedicinska) found that four of 20 packages of Danish pork bought throughout the Stockholm area contained the resistant MRSA bacteria.
A random sampling of German pork found the presence of MRSA in just one of 20 packages.
A similar test in Denmark found the same prevalence of the bacteria
. The Technical University of Denmark analysed 100 packages of Danish-produced pork and found the MRSA 398 bacteria in 21 of them. That represented a steep increase from just five years ago when a similar analysis found the presence of MRSA in just five percent of Danish pork products.
Pigs do not become ill from MRSA and the bacteria is not particularly dangerous for people who are healthy. But for people who are already feeling weak or poorly, exposure to the bacteria can lead to blood poisoning and in the worst cases death.
With the Swedish findings, officials there are concerned.
"It's unlikely that you would become infected through meat but it is unpleasant to know that there are resistant bacteria in the food that you buy," Olov Aspevall, chief physician of the Swedish Public Health Agency (Folkhälsomyndigheten) told Dagens Nyheter.
Last year Sweden imported 142,000 tonnes of pig products, with three quarters of that amount coming from Denmark and Germany.
