What potential dangers can arise from drug residues in animal products?

Drug residues in animal products can significantly impact consumer health and safety, making the choice related to allergic reactions and antibiotic resistance the most relevant concern. When animals are treated with drugs, particularly antibiotics, residues can remain in their tissues and products such as milk, eggs, and meat.

If these residues are ingested by humans, there is a risk of adverse allergic reactions in sensitive individuals, especially if the drugs involved are known allergens. Moreover, persistent antibiotic residues in food can contribute to the development of antibiotic-resistant bacteria, which poses a serious public health threat. Such bacteria can survive treatment and proliferate, leading to infections that are more difficult to treat.

In contrast, the other options highlight aspects that do not directly address the safety concerns associated with drug residues. While increased shelf life, development of new therapeutic drugs, and improved growth rates may be beneficial outcomes in some contexts, they do not encapsulate the dangers posed by drug residues in animal-derived food products. Hence, understanding the implications of drug residues focuses on the potential risks to consumer health and the broader public health concerns associated with antibiotic resistance.
