Conversely to the unethical behavior from PCA and the FDA, other companies that purchased peanut butter or peanut paste from PCA, such as The Kellogg Company and General Mills, voluntarily pulled their products from shelves. Although they were not completely sure that their products were affected, they thought it was the right thing to do so that more people would not be sickened. Even though it hurt them financially, they decided that this would benefit the largest amount of people in the long run. It can be argued that corporations should keep tabs on their suppliers, such as those that purchased from PCA. A utilitarian cost-benefit analysis would have been effective for the companies who did purchase from them. Furthermore, some large food industries companies, such as The Kellogg Company have begun to hire private inspectors to check out plants so that something like this does not happen again. A utilitarian analysis would suggest these are positive ethical strategies.
