Do we have to take ethical permission from the ethics committee for experiments that will be done on detecting bacteria or viruses in food like meat or milk from the markets?
If you are screening for bacteria and viruses from meat and milk which are sold on the open market, then you may want your protocol validated by your institution. There are no ethical issues involved and the clearance of the protocol by an Ethics Committee may not be necessary. Please confirm with your institution. If you will be buying your samples like any other customer on the open market and not asking the sellers any questions, then you do not need to have a signed Research Consent Form. However, if sellers will be responding to some questions, you may want to present them with a Research Consent Form to agree to participate in the study and they should sign the form. The participation of the sellers should be voluntary and this should be clearly stated in your Research Consent Form.
If the samples are sold in the market, they should not require permission from the ethical committee to conduct research on them, because such kinds of studies did not involve any contact with live animals. But if you collect samples of milk from animal fields, you need permission because you have been in contact with animals. In addition, even when the samples are sold in the market, there are journals that claim this permission as part of the instructions for publishing them, and certainly, these instructions are subject to the laws in their countries.
Dear it varies from country to country and region to region in a country. It there is a clear cut policy in a region or country based, it is mandatory to follow, according. There are certain policies where there is no harm to humans and animals from experiments/ spread of disease due to microbes, permission is not required in such scenarios.
