How does the presence of antibiotics affect the milk supply chain?

The presence of antibiotics in milk is a significant concern for the dairy industry and can profoundly impact the milk supply chain. If antibiotics are detected in milk, it raises potential safety concerns for consumers. Milk containing antibiotics is not safe for consumption, as these substances can pose health risks and lead to allergic reactions in some individuals.

As a result of finding antibiotics in milk, producers may have to initiate recalls of affected products to eliminate any safety hazards from the market. This not only impacts the availability of the milk supply but also can damage a brand's reputation and consumer trust. The financial implications of recalls can be substantial due to lost sales, disposal of contaminated products, and costs associated with testing and compliance.

In contrast, the other choices do not accurately reflect the implications of antibiotic presence in milk. While antibiotics can be beneficial in treating dairy cattle for infections, their presence in milk is strictly regulated, and any detected levels can lead to severe consequences for the entire supply chain.
