The reading states that the lead in canned food cause the crew poisoning. On the contrary, the professor thinks that the arguments in reading aren't convincing.

Firstly, the author mentions that lead didn't get into food because melted lead was carefully applied to cans from the outside to seal the lids in place. However, the speaker says that the cans on ships show the melted lead didn't stay on the outside as it was supposed to. In fact, the workers in food company didn't have enough time to seal the lids carefully. So, the melted lead ran down the inside of the cans, contaminating the food.

Additionally, the writer demonstrates that there are no other cases about lead poisoning reported. As a matter of fact, the speaker indicates that sailors on the other ships didn't test for lead poisoning but lead poisoning is difficult to detect without specific tests. The reason is symptoms of mild lead poisoning include tiredness and headaches, which are very common. Therefore, other sailors might overlook the signs and couldn't recognize the problems.

Finally, the speaker contradicts the idea in reading by suggesting that the main purpose of the water purification systems was to provide freshwater for the ships engines instead of drinking or cooking. It is because those engines were steam engines and they must use freshwater. Moreover, there are separate supplies of freshwater on board for drinking and cooking.
