Scientists have created a super-sensitive test that can detect tiny amounts of a drug called ractopamine (and its breakdown products) in animal tissues, urine, and blood — even when those samples are messy and full of other stuff — and it works reliably every time.

Appropriate Language Strength

Assessment Explanation
This claim describes the performance characteristics (detection limits, recovery rates) of a validated analytical method, which are empirically measurable and reproducible under controlled lab conditions. Such claims are standard in analytical chemistry papers and are supported by method validation studies (e.g., linearity, precision, accuracy, LOD/LOQ). The use of definitive verbs like 'achieves' and 'enabling' is appropriate because these are technical performance metrics, not biological effects. No overstatement is present.
More Accurate Statement
“An HPLC-FLD method incorporating enzymatic digestion and solid-phase extraction cleanup achieves detection limits of 1 ng/g in tissue samples and 0.5 ng/mL in urine and serum, with recovery rates ranging from 70.5% to 94.5%, enabling reliable and accurate quantification of ractopamine and its metabolites in complex biological matrices.”

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies

Residue depletion of ractopamine and its metabolites in swine tissues, urine, and serum.
Scientists used a specific lab method to find tiny amounts of a drug in pig tissues and fluids, and it worked exactly as claimed — they could detect very low levels and got consistent results.
