Laboratory workflow using SPE to analyze antibiotic residues in milk samples

SPE Sample Preparation for Antibiotic Residues in Milk

Regulatory Limits for Antibiotic Residues in Dairy Products Antibiotic residues in milk and dairy products are strictly regulated worldwide to ensure consumer safety and prevent antimicrobial resistance. Regulatory agencies including the FDA, EU Commission, and Codex Alimentarius establish Maximum Residue Limits (MRLs) for various antibiotic classes. These limits typically range from 4-100 μg/kg depending on

Solid phase extraction workflow for mycotoxin cleanup in grain laboratory testing

Optimizing SPE for Mycotoxin Analysis in Grain Samples

Overview of Common Mycotoxins in Grain Mycotoxin contamination in grain represents one of the most significant food safety challenges facing the agricultural and food processing industries. Among the hundreds of mycotoxins identified, three classes dominate grain contamination profiles: aflatoxins, deoxynivalenol (DON), and zearalenone (ZEA). Aflatoxins: The Carcinogenic Threat Aflatoxins, particularly B1, B2, G1, and G2,
