quality or the nature of a given substance is reduced through. i.            
The addition of a foreign or an inferior substance. ii.             
The removal of a vital element. ·        
The word adulterated implies on element of deceit. ·        
It means mixing the food with something inferior or spurious. <o:p> </o:p> Food adulterant<div><div style="text-align: center;"> </div><div>    An adulterant is any material
which is or could be employed for making the food unsafe
or sub-standard or mis-branded or containing extraneous matter (FSSAI, 2006).<div>  Types of adulteration <o:p> </o:p> 1.     
Intentional Adulteration. 2.     
Incidental adulteration.   Intentional Adulteration <o:p> </o:p> ·        
Adulterant is added knowingly to increase profit. ·        
This type of adulteration includes intentional
addition, substitution or addition or removal of substances which adversely
affects the quality of food.</div><div>        Eg. Sand, marble chips, Earth and other filth. <o:p> </o:p> Incidental
Adulteration</div><div> </div><div>    Incidental contamination is due to ignorance, negligence or lack of
proper facilities.</div><div>        Eg. Toxic metals, presence of bacterial and
fungal contaminants. <o:p> </o:p> Metallic contamination <o:p> </o:p> ·        
Contamination of food with lead can cause toxic symptoms. ·        
Lead brings about pathological changes in the kidney, liver, and arteries. ·        
The common signs of lead poisoning are nausea,
abdominal pain, anemia, insomnia, muscular paralysis and brain damage. ·        
Fish caught from water contaminated with mercury salt contains large
amount of mercury. ·        
The other elements which are toxic in small doses are
cadmium, arsenic, antimony and cobalt. ·        
Food adulteration is unethical and called as Social Evil and A Slow Poison. <div>Food is
declared adulterated if: ·        
A substance is added which depreciates or injuriously affects it. ·        
Cheaper or inferior substances are substituted wholly or in part. ·        
Any valuable or necessary constituent has been wholly or in part abstracted. ·        
It is an imitation. ·        
It is colored or otherwise treated, to improve its
appearance or if it contains any added substance injurious to health. ·        
For whatever reasons its quality is below the Standard.   Categories of food adulteration <o:p> </o:p> ·        
Replacement:
Complete or partial replacement of a food ingredient or valuable
authentic constituent with less expensive substitute with the intention of
circumventing on “origin” and false declaration of the “process”. ·        
Addition: Addition of
small amounts of non-authenticated substances to mask inferior quality ingredient. ·        
Removal: Removal of
authentic and valuable constituent without purchasers knowledge </div><div> </div><div>Food Adulteration Categories.</div><div><div style="text-align: justify; text-indent: -24px;"> </div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjoBlaHK3M3v43pt_hwtAWhrJrbDjkrwCiD_41H4eTDHOOCF2CibmhiAnNH84tNjvq9QeOsry6-SCuVrvPl-AfecyfOQA7dPy4b-13QOzbnHdc01pngtqFGHgxa2hGh5YAPHgi0X3PjW81s0VFxu_fRsQ4-WEXhi5mVwyBZ_lEjGvarP-euXKfKFcpX" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="997" data-original-width="892" height="580" src="https://blogger.googleusercontent.com/img/a/AVvXsEjoBlaHK3M3v43pt_hwtAWhrJrbDjkrwCiD_41H4eTDHOOCF2CibmhiAnNH84tNjvq9QeOsry6-SCuVrvPl-AfecyfOQA7dPy4b-13QOzbnHdc01pngtqFGHgxa2hGh5YAPHgi0X3PjW81s0VFxu_fRsQ4-WEXhi5mVwyBZ_lEjGvarP-euXKfKFcpX=w582-h580" width="582" /></a></div> <div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgeo1GPWOVDHZiUrejimw30UN0t9o_Mp5XkHC_cBthJNvsdyYIkU-aWRKdltMErBnh-asG8RNz4BeZSpOdTvELsvKDuve9urAlmZfl1tVeJgKHHNRebiPoBWGCp04shzzXXDgfGp8KStqyPaivlr7MplGwLoTytrKeGfjMqLBBtvRouXcnOsSxQVeDy" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="848" data-original-width="750" height="482" src="https://blogger.googleusercontent.com/img/a/AVvXsEgeo1GPWOVDHZiUrejimw30UN0t9o_Mp5XkHC_cBthJNvsdyYIkU-aWRKdltMErBnh-asG8RNz4BeZSpOdTvELsvKDuve9urAlmZfl1tVeJgKHHNRebiPoBWGCp04shzzXXDgfGp8KStqyPaivlr7MplGwLoTytrKeGfjMqLBBtvRouXcnOsSxQVeDy=w583-h482" width="583" /></a></div> </div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjIfsL87QIhLk3VQ_96nVqbA4zoWoDVJNuv7SYng9PUgJnol8tVh8pq68kWt4Yg8s99tm8Cw-w-lgCj581u3JfEHRHrN0BAwSd1v3ba46cAX3Rxnvy7szyoJC-PHKAyWAVYoJQrq1Tu4Chjeof1aMYXYH9OFEm90s3plgzsPS_PHPz_eglng-4pW_a5" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="457" data-original-width="762" height="421" src="https://blogger.googleusercontent.com/img/a/AVvXsEjIfsL87QIhLk3VQ_96nVqbA4zoWoDVJNuv7SYng9PUgJnol8tVh8pq68kWt4Yg8s99tm8Cw-w-lgCj581u3JfEHRHrN0BAwSd1v3ba46cAX3Rxnvy7szyoJC-PHKAyWAVYoJQrq1Tu4Chjeof1aMYXYH9OFEm90s3plgzsPS_PHPz_eglng-4pW_a5=w586-h421" width="586" /></a></div><table cellpadding="0" cellspacing="0" style="text-align: left;"><tbody><tr><td height="0" width="146"></td></tr><tr><td></td></tr></tbody></table> </div><div>Methods for detecting food adulteration <o:p> </o:p> 1.

The microbiology laboratory is one such environment full of microbial flora. In the bioresearch laboratory, the microbes are separated from its native environment and cultured in an artificially controlled environment. The culture conditions in the bioresearch laboratory are designed to achieve the objective of the experiment. In a practical session, those who are present in the bioresearch laboratory will be in direct contact with the microbes. Those who are having low immunity, allergic will have more chances to get diseased while working with pathogenic microorganisms. </div>
