Safety pathogenic microorganisms

HACCP is one of the minimum standards that is often required in a food processing enterprise to ensure that products do not contain harmful levels of biological, physical or chemical hazards such as pathogenic microorganisms or toxins. The overall idea of HACCP is to identify specific CCPs, which are those steps in the production process where the safety of the final product can be controlled most efficiently, and then define systematic procedures for monitoring and corrective action, to ensure that the risk is controlled at each...

Additional safety regulations, which are not discussed here, apply to certain areas of work, notably the use of radioactive materials, genetically manipulated organisms, and pathogenic microorganisms. 

Customers nowadays expect food products to be available all year round, to have a reasonable shelf life and to be free from spoilage of pathogenic microorganisms. Chemical preservatives have helped to increase the safety of the food chain, but in some trends of free from preservatives , manufacturers must ensure that the customer is aware of the need to refrigerate the product once opened. One must balance the need for food safety against the small risk from artefacts due to the microbial system.

This handbook provides basic facts regarding foodbome pathogenic microorganisms and natural toxins. The book includes information from CDC, FDA, USDA Food Safety Inspection Service, and the National Institutes of Health. 

Whether natural or synthetic, any complex ingredient must be examined to determine if its other components are toxic or in any way affect the function of the final product byproducts shown to be of concern should be removed. If appropriate preclinical and clinical evaluations are conducted, this should lessen the safety concern. Sources of new ingredients must be determined to be free of dangerous impurities, such as pesticide residues, heavy metals, toxins, or pathogenic microorganisms. Allergenicity related to the ingredient or byproducts also should be addressed. 

The detection and identification of microorganisms is a problem common to many areas of human and veterinary health. For example, the detection of pathogenic species such as Salmonella typhimurium. Listeria monocytogenes, and Escherichia coli 0157, which are causative agents of major food borne epidemics, is a great concern within the food industry with respect to the quality and safety of the food supply. In other areas of human and veterinary health care, detection and identification of infectious diseases caused by pathogenic microorganisms and viruses...

Personnel in the microbiology laboratory normally have the same safety concerns as those in the chemistry laboratory but, additionally, may face challenges unique to their workplace. These include the potential for unexpected exposure to billions of potentially pathogenic microorganisms, the use of high-pressure sterilization equipment, open flames for aseptic techniques, and extremely toxic media ingredients (e.g., cyclo-heximide, DMDC, etc.). 

Food analysis is a very important field that involves very different applications such as quality food processing, food and health safety, or development of new functional food among other. Therefore, there are many possible analytes all along the food chain, from the farm to the table. It can be cited as most common residues of herbicides/pesticides or veterinary pharmaceuticals, pathogenic microorganisms, and their toxins, toxic substances such as PAHs, additives, and substances related to food allergies, intolerances as well as controllers of food uptake. 

Our food in the U.S. today is much safer than ever in the past, certainly so with respect to pesticide residues, and this record has been conq)iled during a major transition in food delivery that has included much more fresh food, much more ethnic and/or specialty foods, a larger availability of food products, ranging from staples to whole meals prepared in nearly ready to eat form, and increased international trade in food items. The problems in food safety of the past 10-15 years have largely been from pathogenic microorganisms. When chemical residues from pesticides, PCBs and other industrial materials have been problematic, it has largely been because of trade issues rather than any demonstrable threat to the safety of the consumers. 

In conclusion, flavonoids and plant extract rich in flavonoidic compounds as antimicrobial agents present two main positive features the first is their natural origin, which means more safety for consumers, and the second is that they are considered to be low risk for resistance development by pathogenic microorganisms thus they can be considered a valuable support in the treatment of infections and may contribute to the development of new and safe antimicrobial agents.
