Nowadays, biosafety and biosecurity are burning concern among the conscious people but sometimes many people cannot differentiate biosafety and biosecurity. What would be the best answer of this question.
There are a lot differences between the two terms, but the main one is that bio-safety has as target the protection of human and the facilities which are dealing with biological agents and waste against their contamination with the diseases produced by these hazardous materials. On the other hand, bio-security is referring to the protection of high pathogenic biological agents and waste against stilling and using as biological weapons by terrorist organizations.
If you are interested to read and understand more about these terms I would recommend you to visit CDC and ECDC websites where you can find presentations, e-learning materials and other types of publications which will give you more insights on these subjects.
I agree with the response of Mariana but I have a couple of additional observations. I have noticed over the years that there has been confusion between the terms 'biosecurity' and 'biosafety' especially in Europe. This arose because in some European languages such as French and German, there is only one word (biosecurity) to cover both words used in English. In addition, biosafety is also used to cover safety measures associated with the use of genetically modified organisms, for example, in agriculture.
For me, the difference is that one refers to safety and one to security when dealing with bio-organisms and toxins. Safety is obviously more relevant to labs and other facilities that deal with dangerous biologicals, as mentioned above, while security usually refers to preventing import of certain organisms/toxins or protecting people in country and abroad from biologicals.
Biosafety & Biosecurity both are complementry to each other and the basic differences is that lab practices which making safer to Researcher/worker in lab is biosafety.
While Biosecurity are Practices, Procedures and the modeling at broad level to make secure to others one either human beings or animals from pathogenic one...can be reffered as Biosecurity.
Biosafety is the safety of human and environment from unintentional release of pathogenic microorganisms and biohazards. On the contrary, Biosecurity is the protection of human and environment from intentional release of biohazards by an individual.
Biosafety refers to "the containment principles, technologies, and practices that are implemented to prevent unintentional exposure to pathogens and toxins or their accidental release" (WHO, 2018). In other words, it is protecting yourself, others, and the environment from bad bugs.
The term “biosecurity” refers to the “institutional and personal security measures designed to prevent the loss, theft, misuse, diversion or intentional release of pathogens and toxins”(WHO, 2018). In short, it can be said that Biosecurity includes the means to protect bad bugs from bad people.
Biosecurity: when you protect biological waste or products from being accessible, or used by unauthorized parties.
Biosafety: when you protect the biological waste or products from the public to control the spread of infections. Both measures compliment each other in maintaining safe society for human and health personals.
I would like to draw the attention of community of life sciences and other convergent domains on dual use research concern as well as biorisk management. Take a moment to learn a little bit on these fields.
