Biological hazard is the most dangerous and critical because biological hazards, mainly bacterial, can cause either foodborne infections.
Campylobacter and Salmonella are the key causes of food- borne illness of bacterial origin .The more significant hazards facing the food industry today are microbiological contaminants, such as Salmonella, E.
coli O157:H7, Listeria,Campylobacter, and Clostridium botulinum.

An Hazard is only classified when it is suppose to cause harm to human life & therefore any type is dangerous always !!

All  the hazards types are dangerous , many factors are playing role here to let thhe level of risk vary ,,, exposure limits , nature of industry , type of activites ,,,,a fatal accidents can be caused by phiscal hazards , the same can be caused by chemical & biological hazards .....

 

Anyway , the main issue is to focus on hazards recogintion and identification , thenafter , control the hazards either bby elimnation , engineering controls , adminstrative , or PPEs ...

As far as my experience is concerned Chemical Hazard is most dangerous, because in most food processing especially in dairy, the Physical Hazard can be controlled by introducing Strainers or Filtration units, and Biological hazard can be controlled by sterilization,pasteurization,Ultra Heat Treatments, Etc., but once the chemical contamination is occurred it can not be controlled by any means in the Process.

Risk analysis to determine the potential threat for biological, chemical and physical hazardous is important.
We have to determine low(known-known) , medium(known-unknown) and high(unknown-unknown) risks.
If risk is hidden in any case then it is very dangerous because we do not have the plan to control it.
In case of high risk, if it is manageable/ controllable then it is low dangerous.
Biological hazard may be low dangerous if we have total control.
A physical hazard may be very high if we do not control system Regards Syed Burhanuddin Abdali Principal Scientific Officer Pak.Council of Sci.

Biological Hazard is the most critical Hazard as it is found very frequently & have potential threat to human health.
Toxins produced by the microorganisms can be fatal.

Botulism - a species of bacteria can produce a toxin in canned foods which can cause instant death when consumed.
Physical & chemical hazards can occur in food production but the frequency/ probability of occurance is low than that of Biological hazard
