Use this information to answer the following two questions. The pet food contamination issue started March 15, 2007, when the Food and Drug Administration (FDA) was notied that animals were dying from consuming pet food from a pet food manufacturer who had switched suppliers of wheat gluten. The deaths of the animals resulted from renal (kidney) failure and killed up to 1,000 dogs and cats in the U.S.A. 150 brands including Menu Foods pet food, the most affected brand (with 60 million containers), were recalled. This was the largest recall in FDA history and was estimated to have cost Menu Foods $54 million. Other aspects that were affected were production and materialsllabour. However, the magnitude of the loss of life makes any other impacts to the goals less signicant. The contaminated food entered the supply not only because melamine and cyanuric acid (CA) made it into the pet food, but also that it went undetected. The contaminants were added for the purpose of increasing the apparent protein content of the wheat. This was motivated by an overall effort to reduce cost and by the encouraging results from tests of the melamine and CA's ability to mimic protein response in protein testing. However, when it came to standard tests, they were somewhat similar to the reasons the manufacturer chose to use melamine and CA in the rst place: they do a good mimicking protein response. In addition, there are no standards for these contaminants and were therefore not tested. What was the root cause of this food contamination issue? Select one: O a. Owners didn't check the ingredients of the pet food before feeding it to their pets cross out O b. The food manufacturer switched to a different supplier cross out O c. The standard tests were not rigorous and detailed enough to detect contamination cross out O d. The substitute was cheap and degraded the integrity of the overall product cross out Which of the following are symptoms in regards to the food contamination issue? i.) Melamine and cyanuric acid were able to mimic protein response i.) The recall cost pet food brands, like Menu Food, a significant amount of money iii.) The contaminated food entered the supply chain of 150 pet food brands Select one: O a. All of the above cross out O b. None of the above cross out O c. i, ii only cross out O d. i, iii only cross out O e. ii, iii only cross out
