Quantitating antibiotics and insecticides in poultry is serious business. Overuse can lead to antibiotic resistance while insecticide residuals can cause harmful side effects in humans. In the United States, for example, the Federal Drug Administration (FDA), has offered up a plan to limit common antibiotics in feed, which are used to encourage growth. However, this is a voluntary plan, and as the following application note, “Quantitation of Antibiotics and Insecticides in Poultry Feed using LC-MS/MS,” points out, antibiotics have been shown to accumulate in poultry feathers, which are in turn used for nutritional elements in the feed.

One of the biggest concerns of Chinese citizens is food safety1. Even though China ranks second in global economies2, crowding, industrial pollution, labor and certain agriculture practices have contributed to this. In October 2015, however, we began to see a turnaround as the Chinese government revised its 2009 Food Safety Law in an attempt to strengthen its food supply oversight and quality.

Food allergy is an immune-mediated, adverse reaction to an antigenic protein. Even limited exposure to an antigen can provoke a significant reaction in sensitive individuals, causing rashes, itching and swelling in the mouth, nausea, vomiting, and asthma. Additionally, food allergies are the leading cause of anaphylaxis, an acute, potentially deadly allergic reaction. The prevalence and severity of food allergies are rising, with approximately 150 million people suffering from food allergies worldwide.1, 2 Presently, there is no cure for food allergies, and sufferers must rely on the correct labeling of foods to avoid consuming allergens. Hence, the development of sensitive and accurate analytical methods to screen for the presence of allergens in food products is necessary for the prevention of potentially life-threatening health problems for allergy sufferers.

Did you know climate change could be poisoning your food?  According to the United Nations Environmental Program (UNEP) report on Emerging Issues of Environmental Concern, rising temperatures are making crops more toxic.

This second is a blog series on the global war: Rise of Superbugs! Part 1 took a critical look at the antibiotic threat we face in today’s battlefield. The waning effectiveness of antibiotics as we head into what may seem like a post-antibiotic era has impelled new reformation to at the very least control antibiotic usage to ensure food safety.

The term “antibiotic-free” is becoming more and more popular in food advertising these days. Take Subway for example; in March the company elevated their antibiotic-free policy and introduced a new antibiotic-free rotisserie-style chicken sub, and they plan to, “Nix antibiotics in all its meat by 2025.”

These days, it is not uncommon to hear about the overzealous application of pesticides to crops or the injection of antibiotics into animals. From grocery stores to restaurants, our food is at risk. How then, can consumers be assured that chemical contaminants like these , not to mention the risk of mycotoxin compounds are not making their way to your dinner table?

Recent regulations on food analysis require screening for pesticides using confirmatory techniques, such as GC-MS and LC-MS/MS. More than 1000 pesticides are used worldwide and, along with their metabolites and degradation products, are present in food. There is a demand for powerful and rapid analytical methods that can identify pesticides with high confidence in a broad range of food matrices and quantify at low concentrations with good accuracy and reproducibility. Challenges for pesticide residue laboratories at the moment are the request to test for more compounds, in a wider range of samples, all without sacrificing data quality.
