“…En el 100% de las muestras de productos alimenticios industrializados que tienen soya como principal ingrediente se detectaron secuencias transgénicas; por lo que es razonable presumir que la soya es genéticamente modificada. Este porcentaje es superior a los obtenidos en Bosnia y Herzegovina 42,86% (14) , en Egipto 92,31% (15) y en Malasia 93,85% (10) , e igual a los obtenidos en Irán (16) y Turquía (17) . Estos reportes demuestran que en países de diferentes continentes es elevada la comercialización y consumo de alimentos industrializados de soya que tienen componentes transgénicos.…”

“…En la detección de las tres diferentes secuencias transgénicas se evidenció que el P35S es la de mayor frecuencia; lo cual tiene relación con lo reportado por Rabiei et al (18) quienes encontraron que está presente en alrededor del 95% de las plantas transgénicas cultivadas en todo el mundo. Dicha secuencia también es la que se detecta con mayor frecuencia en el análisis de productos alimenticios transgénicos, como lo demostraron estudios similares al nuestro, Mostafa et al (15) en Egipto, quienes detectaron el P35S en el 92,31%, el TNOS y el EPSPS (RR soy) en el 7,69% de 13 muestras; y, Sani et al (10) en Malasia, quienes detectaron el P35S en el 93,85%, el TNOS en el 78,46% y la RR soy en el 86,15% de 85 muestras. Otros estudios tienen resultados más equilibrados en cuanto a frecuencia, sin perder la preponderancia del P35S.…”

Introducción. El consumo de alimentos industrializados que contienen organismos genéticamente modificados (OGM) se ha incrementado notablemente. Desde su inicio ha generado crecientes controversias debido a que se considera de riesgo para la salud. En Perú se carece de información científica sobre los OGM en alimentos industrializados. Objetivo. Detectar y cuantificar molecularmente los indicadores de transgenicidad P35S y TNOS, y la soya transgénica Roundup Ready en alimentos industrializados de soya; y verificar su mención en la etiqueta. Métodos. Analizamos 30 muestras, para extraer el ADN utilizamos los kits Dneasy Mericon Food y Dneasy Power Soil. Para la detección y cuantificación de las secuencias transgénicas usamos la técnica PCR en tiempo real con los kits Mericon. Resultados. Detectamos transgenicidad en el 100% de las muestras y soya Roundup Ready en el 66,7%. El número de copias/mL o g de muestra osciló entre 1,21E+0 y 8,88E+7. En el etiquetado del 93,3% de las muestras no hubo referencia a componentes transgénicos. Conclusión. Los hallazgos evidencian la urgente necesidad de que la legislación vigente se actualice de acuerdo con los conocimientos científicos y el desarrollo socioeconómico del país, protegiendo la salud y el derecho a la información de la población.

“…Sung et al (2015) [30] examined ractopamine residues in 299 imported meat products (154 beef, 88 processed beef products, and 57 pork), and ractopamine residues were detected in two beef samples at concentrations of 0.6 and 2.0 µg/kg, respectively. Mostafa et al (2022) [31] examined ractopamine residues in 21 imported meat products sold in Egypt, among which 10 (including beef, pork, and processed meat) had ractopamine residues at concentrations ranging from 1.14 to 6.30 µg/kg, in compliance with the JECFA standard (10 µg/kg). These results are consistent with the present study, in which, although ractopamine residues were frequently detected in imported meat, the residue concentrations were less than 10 µg/kg.…”

Beta-agonists (β-agonists) in meat products in one’s diet raise concerns about the possibility of foodborne illness. It may also lead to discomfort, such as headaches and occasional irregular heartbeats, which might be linked to a heightened concern for cardiovascular issues. Taiwan’s high demand for meat and reliance on imported meat products from certain countries where β-agonists are permitted has raised concerns. Recent import border checks and monitoring of meat products in the market have revealed the concentration of non-compliance with β-agonist residue regulations, which is ten ppb. This study aims to analyze the concentration of β-agonist residues in meat products sold in Taiwan and assess the current levels of exposure and dietary risk for consumers. The study analyzed 1415 samples of domestically produced and imported livestock products from supermarkets, traditional markets, and bulk stores in New Taipei City between 2019 and 2023. The samples were analyzed using the method for detecting 21 β-agonists based on the Taiwan Food and Drug Administration’s specifications. Estimated daily intake (EDI) of β-agonists for different age groups and the target hazard quotient (THQ) were used to assess dietary exposure and risk. The results showed that all 1415 samples were compliant with regulations. Among them, 43 beef samples showed residues of ractopamine originating from the United States, with residue concentrations ranging from 1 to 10 μg/kg and an average residue concentration of 3.3 ± 1.9 μg/kg. Under average consumption, the highest EDI for the exposed population was observed in the 6–12 age group, with values of 0.1469 μg/kg/day, 0.0734 μg/kg/day, and 0.0242 μg/kg/day for the three residue concentrations (maximum detected residue, maximum allowable residue, and average detected residue, respectively). The THQs for ractopamine in imported beef samples were all less than 1, indicating no health hazards at the current intake levels of each age group and the residue concentrations in commercially available beef. Despite the findings, traders need to acknowledge regulatory variations between Taiwan and exporting countries when importing meat products. Traders should provide inspection reports to monitor β-agonist residue levels in imports or explore sourcing beef from countries with β-agonist bans.

“…Catecholamines (CAs) are a group of organic compounds consisting of a hydroxyl group and an amine side chain. Most CAs are used by dopamine, norepinephrine, and epinephrine receptors in the nervous system [ 49 , 50 ]. CAs have received the attention of researchers because of their early recognized involvement in different neurological disorders [ 51 ].…”

“…The Codex, an intergovernmental food standard-setting body with more than 180 members, ratified an MRL for RAC at 10 parts per billion (ppb) in pork and beef muscle meat [ 109 ]. Specifically, the Codex has recognized RAC maximum residue limits of 90, 40, 10, and 10 μg/kg for kidney, liver, fat, and meat, respectively [ 50 ]. The levels agreed upon were significantly higher than what many countries wanted.…”

Ractopamine (RAC) is a synthetic phenethanolamine, β–adrenergic agonist used as a feed additive to develop leanness and increase feed conversion efficiency in different farm animals. While RAC has been authorized as a feed additive for pigs and cattle in a limited number of countries, a great majority of jurisdictions, including the European Union (EU), China, Russia, and Taiwan, have banned its use on safety grounds. RAC has been under long scientific and political discussion as a controversial antibiotic as a feed additive. Here, we will present significant information on RAC regarding its application, detection methods, conflicts, and legal divisions that play a major role in controversial deadlock and why this issue warrants the attention of scientists, agriculturists, environmentalists, and health advocates. In this review, we highlight the potential toxicities of RAC on aquatic animals to emphasize scientific evidence and reports on the potentially harmful effects of RAC on the aquatic environment and human health.
