This forum is for the open exchange of recipes, knowledge and ideas pertaining to food preservation.
As with any open forum, there are differing opinions on methods and processes involved with food preservation and therefore we encourage constructive and polite interaction among our users.
There are several agencies in various countries that publish canning standards and that information can vary by organization and country. Differing opinions on methods (i.e. - 'is this safe?) are exactly that...opinions, based on the advice you have gleaned from your experience and information from canning companies, research groups, and governmental agencies.
When posting, please keep in mind that there may be more than one acceptable standard. We are all here to promote food preservation and share our knowledge with other members. Therefore, when responding to a question like the above, we request that you state that it is your 'OPINION' whether you feel something is safe or not.
It is NOT acceptable to state that just because a recipe has not been tested in a laboratory of your choosing, it is not safe. If that is the way you feel, then you don't belong here, you should be at your country's Food & Drug regulatory website.
We appreciate your input and all that you do and contribute to Food.com and we hope you continue to be polite and respectful to your fellow members and enjoy all that Food.com has to offer.
