Please answer only question #3 with the plate I'm sorry, I can't transcribe the text from the image. **Investigation of Dairy Pasteurization Processes**A USDA inspector is tasked with investigating a dairy whose pasteurization processes are suspect. After inspecting the farm and the milking sheds, the inspector collected several samples of pasteurized milk and sent them to the lab for analysis.**Standards and Requirements:**- New York State standards for safe milk require that the bacterial counts for CFUs/ml should not exceed 20,000 CFUs/ml.- The total coliform amount should not exceed 10 CFUs/ml.**Tasks:**1. **Research Question:** - **Given the amount of bacteria that could be present in the pasteurized milk, explain why it would be necessary to use serial dilutions to accurately determine the CFUs/ml.**2. **Laboratory Procedure:** - The procedure used for serial dilutions is given below. 0.2 ml from each of the indicated dilutions was used to inoculate plates. The CFUs/plate are noted. - **Note:** Pay very close attention to how the dilutions were done. **Questions:** - (a) What is the dilution factor for each tube (1-5)? - (b) Determine the number of CFUs/ml in the pasteurized milk from the dairy. Show your work! - (c) Is the dairy in compliance with New York State regulations regarding milk quality? Explain your answer!**Graph/Diagram:**- The image contains a series of test tubes labeled 1 ml and a formula represented by multiple arrows leading into subsequent tubes, showing serial dilution. Each dilution step involves mixing with 9 ml of a diluent.This task involves calculating dilution factors and bacterial counts to ensure that milk safety standards are being met.

The E. coli O157:H7 is the bacterial species responsible for causing disease which typically includes foodborne illness by consuming raw or contaminated food. This raw food also includes raw milk. The cattles are known as the largest reservoir for E. coli O157:H7 bacteria.The name of this medium is EMB agar. EMB stands for eosin methylene blue agar. Eosin blue agar is responsible for preventing bacteria's growth, which is gram-positive and represents a color indicator that helps in differentiating between different strains of bacteria. Lactose fermenting bacteria is responsible for the production of dark color colonies with a shiny green appearance. So this bacteria represented in the figure must be lactose fermenting bacteria as it is producing green color. This bacterium is responsible for the fermentation of lactose into hydrogen sulfide. The USDA inspector is concerned about E.coli O157:H7 as this contaminated milk can be very dangerous and may lead to serious disease if consumed. These diseases include variation in blood pressure, appetite loss, and hydrogen sulfide produced by this bacterium on fermentation of lactose may be fatal if consumed daily. Hence, this figure represents the medium known as eosin methylene blue agar and green color because of the growth of gram-negative bacteria that is fermenting lactose into hydrogen sulfide. USDA inspector is concerned as consumption of the contaminated milk can be fatal if consumed daily.
