Establishment Registration & Process Filing for Acidified and Low-Acid Canned Foods (LACF): Paper Submissions



The Food and Drug Administration is seeking to make it easier for manufacturers of acidified and low-acid canned foods (LACF) to submit information about their manufacturing processes to FDA and to improve the accuracy of the information they provide. FDA is doing this by modernizing both the paper and electronic process filing forms that acidified and low-acid canned food manufacturers are required to file with the agency under 21 CFR 108.25(c)(2) and 21 CFR 108.35(c)(2).
