Background: A glutenfree diet requires special attention due to the risks of cross contamination, since small amounts of gluten can trigger signs and symptoms and impair the
health and quality of life of celiac patients. Implementing good practices to promote the safe
environment with glutenfree people in glutenshared homes is critical to ensuring a safe home
environment. Objective: To evaluate crosscontamination control practices in celiac
households. Methods: Crosssectional and analytical procedure study, with nonprobabilistic
sampling made by a virtual questionnaire, which evaluated the knowledge of celiac disease,
and a crosscontamination, and some practices that prevent the gluten contamination. To
analyze estatistically, the Spearman correlation test was used, with 5% of significance. Results:
98.63% of the individuals study and research about celiac disease, 97.26% know what is cross contamination by gluten; 87.67% of them reported suspecting having suffered cross contamination. As for the evaluation of crosscontamination control practices, of the 12 items
presented, 5 showed a hit percentual below 50%. The action that had the lowest hit percentual
was the use of commom surfaces (34%). Conclusion: There is still considerable lack of practice
in controlling crosscontamination, which can impact negatively the treatment and life quality
of celiacs.
