Farm animals can carry salmonella, a kind of bacteria that can cause severe food poisoning. However, animals fed antibiotics can carry especially deadly strains of salmonella. In Minnesota in 1983, 11 people were hospitalized with salmonella poisoning. This number itself was not striking at all. Forty thousand Americans are hospitalized with salmonella poisoning every year. What was striking about the cases in Minnesota was that each patient had severe symptoms and all the patients were infected with the same, rare strain of salmonella, resistant to several common antibiotics. A young scientist, Scott Holmberg, noted that eight patients were taking the same antibiotics for sore throats. He ruled out the possibility that the antibiotics themselves were infected with the bacteria because three of the patients were not taking antibiotics at all. He later showed that the people were infected with salmonella prior to taking the antibiotics, but that the antibiotics triggered the onset of salmonella poisoning. He postulated that salmonella suddenly flourished when the patients took antibiotics, because the antibiotics killed off all other competing bacteria. He was also able to trace the antibiotic resistant salmonella to the beef that was imported to Minnesota from a farm in South Dakota, at which cattle were routinely fed antibiotics and at which one calf died of the same strain of salmonella.Based on the passage, which one of the following statements is false?
Minerals are an important component of the human diet. Some minerals are needed in relatively large amounts. These include calcium, phosphorus, potassium, sulfur, chlorine, and magnesium. Others, including iron, manganese, and iodine, are needed in smaller amounts. Humans need 26 minerals all together, but some of them are only required in tiny amounts. Some minerals, such as lead and selenium, are harmful in large quantities. Dietary supplements can decrease the chance of mineral deficiencies listed in the table below, but should be taken with great care, since overdose can lead to poisoning.Taking several iron supplements per day can
