Chlorate can contaminate food due to the use of chlorinated water for processing or equipment disinfection. Chronic exposure to chlorate in food and drinking water is a potential health concern. The current methods for detecting chlorate in liquids and foods are expensive and not easily accessible to all laboratories, highlighting an urgent need for a simple and cost-effective method. The discovery of the adaptation mechanism of to chlorate stress, which involves the production of the periplasmic Methionine Sulfoxide Reductase (MsrP), prompted us to use an strain with an fusion as a biosensor for detecting chlorate. Our study aimed to optimize the bacterial biosensor's sensitivity and efficiency to detect chlorate in various food samples using synthetic biology and adapted growth conditions. Our results demonstrate successful biosensor enhancement and provide proof of concept for detecting chlorate in food samples.

Article Synopsis
- The study developed a reliable LC-MS/MS method for detecting harmful chemicals (thiocyanate, perchlorate, and chlorate) in edible microalgae, showing strong validation with excellent performance metrics.
- A total of 77 microalgae samples were analyzed, revealing that thiocyanate was consistently present at high levels, raising concerns about dietary exposure risks.
- While perchlorate and chlorate posed minimal risks, the findings emphasize the need for better safety standards in microalgae products, particularly regarding thiocyanate.

Chlorate, mainly used in the production of fireworks, herbicides and other products, is an inorganic pollutant, which easily dissolves in water and is difficult to degrade. Chlorate has a potential toxic risk to the thyroid function, kidneys, and blood system, which could pose a potential threat to human health. However, studies focusing on human exposure to chlorate are scarce, especially via food consumption.

Perchlorate and chlorate are recognized as ubiquitously inorganic pollutants inenvrionment owing to their high solubility in water and resistance to degradation. Previous studies have confirmed the potential adverse effects of perchlorate and chlorate on human thyroid function, along with implications for fetal growth and development. The fetus grows and develops pregnant women's womb and absorbs nutrients from her body.

Article Synopsis
- Ion exchange chromatography-tandem mass spectrometry (IEC-MS/MS) is a new technique developed for quickly detecting chlorate and perchlorate residues in tea samples.
- The optimal process involves ultrasonic extraction with a methanol-water mix, followed by purification using a specific solid-phase extraction column, and employs exact conditions for separation and detection.
- Tests showed high accuracy, with excellent linearity for the substances tested across a range of concentrations, and successful application in analyzing 15 tea samples from a local market.
