Discussion rates much higher than those seen developed countries. It should noted that these findings assessed basis criteria (such MRL) obtained Our confined sold few central provinces Thailand did reflect whole country sample sizes small. Risk assessment due consuming contaminated vegetables, still remains evaluated. However, remarkably high give warning Thai authorities implement proper regulations program. Similar contamination question regarding quality organic domestically conclusion excludes export fruits routinely monitored before exporting.
