Mapping Food Hygiene with Open Data
Liam Curley, a UK-based online marketer, has created a data visualization that plots the hygiene levels of businesses that serve food in London, ranging from restaurants to hospitals. The visualization relies on publicly available data from the Food Standards Agency, the UK’s food safety regulator, and OpenStreetMap, an open source mapping platform. Users can zoom in to the thousands of color-coded points on the map to identify individual food-serving establishments and their hygiene ratings. Curley created the visualization after contracting food poisoning from a take-out restaurant, which prompted him to investigate why many food-serving establishments, including those that serve children or sick people, do not advertise their hygiene score.
