Resumo: 	The live food enrichment technique using emulsions for nutritional deficiencies in rotifers and &lt;i&gt;Artemia&lt;/i&gt; was further investigated as a tool for transferring therapeutics through the food chain. &lt;i&gt;Artemia&lt;/i&gt; nauplii and the rotifer &lt;i&gt;Brachionus plicatilis&lt;/i&gt; were enriched with a self-emulsifying concentrate in which the therapeutic mixture trimetoprim: sulfamethoxazole was incorporated. An analytical method and protocol for the quantification of trimethoprim and sulfamethoxazole in a heterogeneous biological matrix, such as &lt;i&gt;Artemia&lt;/i&gt; , was developed using High Performance Liquid Chromatography. When applying a 24h enrichment period, the accumulation of both drugs in &lt;i&gt;Artemia&lt;/i&gt; nauplii appeared to be linearly related to the concentration of the drugs in the enrichment product. Values of approximately 790 mg/kg of total drugs (protein basis; or 290 mg/kg on dry weight basis) could be obtained. In rotifers, the level of total therapeutics reached a value of about 116,mg/kg (protein basis) after 6h of enrichment. The ratio of the two drugs detected in rotifers was different from the one found in &lt;i&gt;Artemia&lt;/i&gt; , suggesting different accumulation kinetics.
