Maybe listen to this one BEFORE you eat… James is off to meet the sewage scientists trying to stop the next pandemic. He meets the teams that were monitoring 80% of people’s faeces during Covid-19 and finds out how sewage led to hundreds of thousands of children having an emergency polio vaccine. James needs to collect a sample at a water treatment works and then head to the laboratory… just be glad you can’t smell a podcast.
