Health education: A Vital tool in changing environmental hygiene knowledge, attitudes and practices among food handlers in a tertiary care hospital of Delhi

Abstract

BackgroundEnvironmental hygiene in food establishments is an important determinant of health. Health education package using combination of strategies is essential in preventing cross-contamination. ObjectiveTo determine change in environmental hygiene knowledge, attitudes and practices among food handlers following implementation of health education intervention. MethodsA before and after interventional study was conducted on 111 food handlers of food establishments in a tertiary care hospital of Delhi in 2021–22. Tool based on WHO & FSSAI guidelines was prepared with a scoring system to rate environmental hygiene knowledge (0–12), attitudes (0–10) and practices (0–12) including cleaning of surfaces, pest control, waste disposal & segregation, packaging of food along with utensil washing steps (0–10). Health education was given and scores on same tool were reassessed after 8 weeks of intervention. Nail bed swabs were taken as an indicator of bacteriological contamination. ResultsThe differences of mean scores of knowledge, attitudes and practices before & after intervention were statistically significant differences of 9.95 ± 0.95, 8.02 ± 0.68 and 7.91 ± 1.16 respectively (p < 0.05) while utensil washing practices before and after intervention were 2.78 ± 0.59 & 6.77 ± 0.74 with statistically significant difference of 3.99 ± 0.85. Before intervention, pathogenic organisms were isolated in nail bed swabs of 91 % of study participants while after intervention it was 12.6 %. Common species isolated were Klebsiella spp. (55.5 %), E. coli (15.9 %), Staphylococcus spp. (10.9 %) and Acinetobacter spp. (9.9). ConclusionImprovement in environmental hygiene KAP emphasizes need of ensuring implementation of existing guidelines. Thus, health education using planned combination of channels and strategies can achieve desired change.
