Resistant bacteria can spread through the food chain, the environment, and direct human-animal interactions, posing a severe threat to public health.
This issue not only undermines the effectiveness of antibiotics in treating human and animal infections but also increases the risk of untreatable diseases. Antibiotic resistance is a global crisis that requires immediate action to address misuse in both agriculture and healthcare.
2. Residues In Animal Products
Improper use of antibiotics or failure to adhere to withdrawal periods can result in drug residues being present in meat, milk, and eggs. These residues can pose health risks to consumers, including allergic reactions and long-term effects from chronic exposure.
Regulatory agencies set strict limits on antibiotic residues, but non-compliance or inadequate enforcement can compromise food safety. This issue underscores the need for responsible antibiotic use and rigorous testing to protect public health.
3. Environmental Contamination
Antibiotics used in livestock farming can enter the environment through animal waste, runoff, and improper disposal of medications. When manure containing antibiotic residues is used as fertilizer or runoff enters water systems, it can contaminate soil and aquatic ecosystems. This contamination affects wildlife, disrupts microbial communities, and contributes to the spread of antibiotic-resistant genes in the environment.
Over time, the accumulation of these substances can lead to ecological imbalances, harming biodiversity and the health of natural ecosystems. The environmental impact of antibiotics in livestock farming highlights the need for improved waste management practices and sustainable farming approaches.
