Veterinary drugs are used in animal production to treat diseases, prevent infection and protect growth of animals, which helps provide quality marketplace. However the uncontrolled use may cause heavy human disease so regulatory agencies around the world have established maximum residue levels (MRLs) or tolerances of veterinary drugs in foods. Drug analysis is generally challenging, due to the complexity of sample matrices and diversity of analytes from various classes of chemical properties. In this study, a fast, sensitive and selective method has been developed for analysis of 73 veterinary drugs (covering 13 different chemical classes) in chicken samples by coupling solvent extraction method with LC/MS/MS.

A New, Sensitive Method for Lignan Metabolite Detection of Flaxseed-Fed Mice Using LC/MS/MS

Per- and polyfluoroalkyl substances (PFASs), or Per- and polyfluorinated compounds (PFCs), represent a group of anthropogenic chemicals that have been produced and widely used in industrial applications and consumer products since the 1950s. The unique physical and chemical characteristics of these compounds (highly stable and resistant to degradation), along with their ubiquitous use, have led to the accumulation of PFAS in the environment, with growing concern of human exposure to these chemicals. The most widely used analytical method for PFAS monitoring is LC/MS/MS owing to its high sensitivity, selectivity and robustness. Recently, with the advancement and availability of highly sensitive mass spectrometers, a trend towards developing a high throughput analytical method for monitoring PFASs by direct injection without SPE has been appreciated. The direct injection approach can achieve higher levels of sample throughput, and reduce potential analyte loss and contamination caused by SPE sample preparation, as demonstrated by this study using PerkinElmer’s QSight^® 420 mass spectrometer, coupled with UHPLC for the determination of trace amount of PFOA and PFOS in drinking and surface water samples.

Testing for the levels of pesticide and mycotoxins in cannabis is important to ensure consumer safety and quality control.

A LC-MS/MS instrument was used with ESI and APCI sources and a simple solvent extraction method with excellent recoveries for all analytes in acceptable range of 70-120%.

Acrylamide is a probable carcinogen organic compound that is found in some foods that are cooked at elevated temperatures. It’s origins are due to the condensation of the amino acid asparagine and glucose as part of Maillard reaction. In 2002, Acrylamide was found to be present in french fries and baked bread. This compound has now also been found in some other food stuff like coffee, black olives, dried pears, and peanuts. As a result the and World Health Organizations have promptly limited its presence for human consumption.

Estrogens play an important role in human breast carcinogenesis and are of clinical importance. Currently, the most widely used techniques are automated immunoassays, owing to the fast sample throughput and minimal sample preparation required. However, these techniques suffer from poor accuracy and precision at low concentration levels, and are susceptible to interferences. The objective of this study was to develop a highly sensitive method for the analysis of estrogens in serum, without derivatization, using the QSight® 420 LC/MS/MS system.

Due to the large number of pesticides potentially used in rice production, the use of multi-residue methods capable of determining many pesticides in one single run is the most efficient approach.

Since 2003 the usage of azo and non-azo dyes for food coloring has been declared as illegal by many of the food international authorities across the globe. That is because these substances such as Sudan I,II,III,IV and Rhodamine B, are potentially carcinogens and genotoxin in nature. As of now, no official methods have been published for the detection of illegal dyes however, the most used analytical technology is GC-MS or HPLC coupled with UV or MS detection.

Fipronil is a broad-spectrum phenylpyrazole insecticide almost used to protect corps from insects but also to treat lice and ticks in chickens. The U.S. EPA classified fipronil as Group C, possible human carcinogen, therefore International organizations defined admissible limits for the fipronil usage which in egg is of 5 µg/L4. LC-MS/MS technology can provide a robust and reliable method to detect such a contaminant in food.

Aflatoxin B1 is often found in animal feeds such as corn, cottonseed cake, groundnut meal, and other agricultural commodities. When these contaminated feeds are ingested by milk-producing animals, such as cattle, aflatoxin B1 can be converted to aflatoxin M1 (a hydroxy derivate of aflatoxin B1) by oxidation metabolism, and then excreted in milk. To protect consumers from the potential toxicity and carcinogenicity of aflatoxin M1, regulatory agencies have established regulatory limits or action levels for aflatoxin M1 in milk products.

In this study, a simple, fast, selective and sensitive LC/MS/MS method for the analysis of aflatoxin M1 is presented, along with the evaluation of three sample preparation methods.
