IBM's new software tracks food contamination

(author Laurie Burkitt)

IBM researchers in China are developing new software to help consumers and businesses track the food they eat from production to dinner, to avoid the pollution problems that global food manufacturers and consumers suffer.

The "Food Safety Simulator" is designed to train shoppers on food reliability and equip them with a mobile application that allows them to scan the product's bar code to see how secure it is. IBM will use star ratings such as security checks, supplier records, and recent recalls. A higher star rating means that shoppers can buy with confidence.

The software has entered the final of this year's "Asian Innovation Award", it can show the comparison between products and competitors and allow users to report health issues. At present, the software is not yet available for sale, and IBM cannot predict when it will be released.

The software also works with manufacturers to use risk models and likelihood assessments to identify sources of contamination and control the spread of contaminated products to consumers.

IBM researcher Cao Rong said that products such as ham are made from different ingredients in the factory. Many kinds of meat are likely to come from many suppliers and are mixed into sausages. He said: "If consumers become ill after eating ham, it is impossible to attribute a ham to a supplier or a pig in most cases."

IBM's services cannot directly link contaminated ham sausages with diseased pigs, but it allows manufacturers to better judge pollution sources and identify problems in the food production process. The "Food Safety Simulator" tells companies what data they need to collect, such as the amount of ingredients, food temperature, and time of all processes. Then it analyzes the collected data to find weaknesses.

For products such as ham, it tracks the mix of pork and flour, the packaging process, and shipping time. If the consumer reports a problem, the manufacturer of the sausage ham can see where the problem is and determine whether there are other products that are contaminated.

The "food safety simulator" has limited effectiveness. In China, food safety problems often occur at the source of supply rather than at the manufacturer. A small farm with more than 50,000 food suppliers with less than 10 people grows agricultural products and livestock for larger food producers. Although larger food producers can track the safety of their production processes, they also need to ensure that the food sources they use are also safe.

Food manufacturers also need to adjust production steps so that they can collect data at various stages of the production process, which may slow the speed of food shelves. However, Cao Rong said that the software's risk model will still help reduce the number of diseases caused by spoiled foods. According to the World Health Organization, 2.2 million people die every year due to diseases in food and water.

After the outbreak of E. coli in Europe in May resulted in 48 deaths and 4,000 illnesses, food safety has been a concern.

IBM researchers say that "food safety simulators" can be used by the government to assess how changes in the control of refrigeration temperatures will affect the quality of food and strains in transportation and production.
