As a major outbreak from a new strain of E. coli makes headlines, we ask: what makes food safe? How are food producers coping with new strains of food pathogens? And what does safe food even mean in a world where processed food is increasingly seen as the top cause of dietary ill health? Meeting over a platter of various foods from raw milk cheese to salad, Sheila Dillon and producer Nina Pullman hear from microbiologists, food safety experts and cheese makers to hear the challenges of staying ahead of the curve when it comes to food and science. They speak to a scientist testing bacteria-eating viruses that can be inserted into feed or food packaging to tackle these new E. colis, known as STECs, and they chat to a global expert in food microbiology on how climate change is making pathogens more difficult to predict.
While such pathogens can get into a variety of foods, raw or unpasteurised cheese makers are feeling the pressure more than most due to the perception of risk around their products. Cheese makers at a panel in London explain the human impact on a small family business that is linked to an outbreak, while a tour of Neals Yard Dairy reveals the number of cheesemakers considering turning to pasteurisation due to fears around the new strains of STEC E. colis.
In a conversation about food that makes us sick, Sheila also meets members of the pubilc who took part in a recent national conversation on food for their views on food safety more broadly. What does food safety mean to them and what do the public expect from food?
