Commodity Specific Analysis

In addition to general purpose screens which are applicable to most types of food crops, Columbia Laboratories specializes in pesticide screens and other groups of tests designed for specific commodities. Our customers often are key partners in the design of these profiles.

Common Commodity Profiles

  • Apple/Pear (P2900) Updated
  • Honey (P4000)
  • Mint (P2450 & P2451)
  • Onion (P3200)
  • Potato (P2400 & P2401)
  • Strawberry (P3500)
  • Sweet potato/Yam (P4400)

Domestic Profiles

For general purpose screening the Columbia Pesticide Profile (P2220) is the most comprehensive and economical screen we offer. However, sometimes it is necessary to focus on pesticides used on specific commodities. In that case, there may be compounds applied which cannot be easily determined by the P2220 methodology. And some compounds which are detectable by the P2200 are not applied or of interest. In situations such as this, we are able to work with our customers to design special combinations of pesticides specifically for their commodity. Since these types of profiles might include pesticides which must be determined using individual (specific) methods, the cost may be higher than the P2200. However, where possible we will combine pesticides into groups which are analyzed using a similar methodology in order to minimize the cost.

EU Profiles

Food products which will be exported to European Union countries must meet their pesticide MRL standards. We are able to help by designing pesticide profiles for those products. Most countries will perform their own testing on imported food products. However, if a violative residue can be detected before shipping much expense can be avoided as a result of having the
shipment rejected.

Japanese Positive List Profiles

In May 2006 Japan initiated the “Positive List” system. Under this system MRL’s are established for over 750 agricultural chemicals, varying by commodity. In cases where no MRL is established a “uniform limit” of 0.01 ppm applies. Food which does not conform to these MRL’s cannot be sold or used in Japan. Companies who wish to export to Japan must ensure that their products comply or risk losses. The Japanese government does not require foreign exporters to

test their products, since they will be performing their own testing when the commodity reaches Japan. However, Japanese importers will likely require it before they will risk buying foreign products. To analyze for all chemicals on
the positive list would be prohibitively expensive for most exporters.

A knowledge of which chemicals are being used by the growers on a particular crop can be very helpful in reducing the cost of testing. From the beginning of the positive list implementation, we have helped our customers develop pesticide screens for products to be exported to Japan. And Columbia Food Laboratories is on the Japanese Ministry of Health, Labor and Welfare’s list of registered foreign laboratories. Please contact us for assistance.
