Anresco Laboratories has been a pioneer in the field of pesticide residue testing for the agriculture industry. Over 25 years ago Anresco partnered with Nutriclean, now SCS (Scientific Certification Systems), to develop one of the first programs in the world to certify produce as “pesticide residue free”, with far more extensive and stringent testing requirements than of today’s organics programs. Today, we work with a number of growers to ensure pesticides are used in a safe and appropriate manner.

Anresco also provides comprehensive microbial and chemical testing services. Since the passage of Prop 65 in California, the presence of certain chemicals, especially heavy metals in or on produce, has been a major concern for the industry. Anresco partners with producers to ensure their products are free of these contaminants and are protected from frivolous lawsuits.
