QUALITY SCORE FOR A FOOD SUPPLY CHAIN

One embodiment provides a method, including: obtaining, for each step in a food supply chain, information corresponding to extraneous factors, wherein the extraneous factors comprise factors that may affect quality of a food product within the food supply chain; generating a rating, for each step in the food supply chain, indicating a level of pollution to which the food product was exposed at the corresponding step, wherein the rating comprises (i) scoring each of the extraneous factors based upon a level of pollution identified from the extraneous factors and (ii) aggregating the scores for the extraneous factors to determining a rating; generating, using the rating for each of the steps, an aggregate food supply chain score for the food product, wherein the aggregate food supply chain indicates an impact of pollution across the food supply chain on the food product; and producing a quality rating for the food product.
