There's a simple test using a gel strip that can spot tiny amounts of two banned animal drugs—salbutamol and ractopamine—in pork, right at the farm or market, and you can see the result with your eyes alone.
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
definitive
Can make definitive causal claims
Assessment Explanation
The claim specifies a precise detection limit (0.5 μg/kg) and a defined method (gel-based immunoassay) with a visual readout, which are common in lateral flow immunoassays. Such assays are routinely validated for veterinary drug residues in food, and visual detection limits are standard reporting metrics. The claim does not overstate mechanism or generalizability—it describes a specific analytical capability. Definitive verbs are appropriate because the claim is about method performance, not biological effect.
More Accurate Statement
“A gel-based immunoassay can detect salbutamol and ractopamine residues in pork at a visual detection limit of 0.5 μg/kg for each compound, enabling rapid on-site screening without instrumentation.”

Development and Application of a Gel-Based Immunoassay for the Rapid Screening of Salbutamol and Ractopamine Residues in Pork.
Scientists made a quick test using a gel that can spot illegal drugs in pork by just looking at it — and it works at the exact low level claimed: 0.5 parts per billion. It’s fast and works in the field.
