Charm Sciences, Inc. is pleased to announce the Charm CowSide II test has completed ILVO validation. CowSide II is a 3 hour qualitative test of raw milk for inhibitory substances including residues of antibiotics. The method meets Belgian FASFC acceptance criteria for detection capability allowing use at milk control stations. The test was evaluated visually using multiple brands of dry well incubators for vials: a 4 place and 20 place incubator manufactured by Charm Sciences Inc., and a 10 place Delvo® incubator supplied by DSM used by many farmers in EU and USA. “The Charm CowSide II test is a broad-spectrum inhibition test typically used for the screening of raw commingled and ultra-pasteurized cow milk,” said Ingrid Huntley, Global Technical Services Specialist for Charm Sciences. “It detects all major classes of antibiotics: beta-lactams, sulfonamides, tetracyclines, macrolides, and aminoglycosides. Eleven drugs are detected at or below US target levels and 30 drugs at or below EU MRLs. This approval will have a significant, positive impact on in the EU marketplace by providing another tool for simple drug residue screening at the farm level.” CowSide II kits consist of single service vials that contain pre-measured bacterial spores, media, and pH indicator. The starting color in the vial is blue/purple. Milk is added to the vial and incubated. If antibiotics are absent, spores germinate and grow, which changes the color to yellow or yellow/green. If antibiotics are present in the milk, microbial growth is inhibited and the positive sample remains blue/purple. About Charm Sciences, Inc.

Implementations of stringent food safety regulations, growth in allergic reactions among the customers and increasing contamination of food processing industries are some of the key factors driving the global residue market. Chromatography is one of the techniques used to test the residues in food which is anticipated to form a fastest growing segment in residue testing market during the forecast period. Various methods are used in finding of contaminants which include food allergens, pathogens, toxins, pesticides residue and heavy metals. The market for the pesticides residues testing is having highest market share presently. The use of harmful pesticides is highly regulated in North America and European region and their supply for some pesticides is under strict control. The situation in Asian countries is quite different. DDT (dichlorodiphenyltrichloroethane) is used in some Asian countries such as India while it is banned in the US. The residue testing market is likely to get benefit from the strong growth demand for specialist diets and packaged foods. The dissolution for trade obstacles and the resulting improvement in the international food trade has augmented the necessity for consolidation of residue testing regulations. New emerging markets such as Asia-pacific with high potential for residue testing market is expected to fuel the future growth because of the high reliance on agricultural commodity exports. Various countries from developed regions have implemented the tolerance levels in food products which are acting as a driver for residue testing market. Recent advancements in the microbial testing methods are anticipated to spur the global residue testing market during the forecast period. Based on the type the global residue testing market is segmented into: Based on the technology type the global residue testing market is segmented into: Based on the Food Tested the global residue testing market is segmented into: In terms of geography, the global residue testing market has been divided into five key regions including North America, Latin America, Europe, Asia-Pacific and Middle East & Africa.The global residue testing market is expected to register healthy CAGR during the forecast period. North America is anticipated to be dominant for global residue testing market followed by Asia Pacific and Europe. The China residue testing market is expected to be the fastest-growing market in Asia-Pacific region as China exports a large amount of agricultural goods to the European market. Some of the key players in the global residue testing market are VICAM LP, Neogen Corporation, IDEXX Laboratories Inc., Charm Sciences Inc. etc.

Label complexes, lateral flow apparatus and methods of detecting a high molecular weight substance are shown and described. In one embodiment, the label complex includes an antispecies antibody and another antibody having sensitivity to both the antispecies antibody and to a control line capture agent, an antibody binding protein and a detectable component. Typically, the antibody binding protein may bind to a receptor for the analyte or to the anti-species antibody. In yet other embodiments, a lateral flow test strip includes the label complex and a solid support that traverses lateral flow of a liquid sample and provides a detectable signal.

Culture medium devices and systems are shown and described. In one embodiment, the device comprises a culture medium adapted for test fluid inoculation without the concerns associated with a spreading step. In particular examples, a printed grid on the outer surface of a culture device is visible on the inner surface for colony counting after a test has been developed. The result is a device that allows for detection, identification, and transportation of various microorganisms without preparation or spreading steps, and more particularly to a culture medium in which a test fluid inoculated thereto diffuses rapidly.

A method and composition for extracting an analyte from a test sample such as grain, so as to determine whether the test sample is contaminated with a toxin. The method is particularly useful for detecting the presence in a batch of grain of a mycotoxin, such as for example aflatoxin, ochratoxin, T2, zearalanone, vomitoxin (deoxynivalenol a/k/a DON), patulin and fumonisin. Extraction is performed with use of a composition that includes a proteinaceous material, such as albumin, as an extraction agent.
