Prevalence and Associated Factors of Intestinal Parasitic Infections among Food Handlers in Mettu Town, Southwest Ethiopia

Abstract

Food handlers are important sources of intestinal parasitic infection to the public and mass catering service areas. Several reports worldwide particularly in developing countries showed a high prevalence of intestinal parasitic infections among these groups of individuals. In an attempt to determine the prevalence of intestinal parasites, a cross-sectional study was carried out among food handlers in food establishment areas of Mettu town, Southwest Ethiopia. To collect sociodemographic characteristics of the study participants, a structured questionnaire and physical observation were employed. Stool specimens collected from each food handlers participated in the study were then examined using light microscopy of the wet mount followed by formol-ether concentration methods to see infection status. A total of 139 food handlers were enrolled in the study. Majority of them were females 89 (64%), and 124 (89.2%) of them had not taken any training related to food handling and preparation. Sixty-two (44.6%) of the study participants were diagnosed with one or more intestinal parasites. The chi-square test showed that intestinal parasite infection was found associated with personal hygiene ( p ≤ 0.0001), nail trimming status ( p ≤ 0.0001), and hair cover status ( p ≤ 0.040). The multivariable logistic regression indicated that the risk to be infected with intestinal parasites were related with older age ( p ≤ 0.032), food handlers who had no hand wash practices ( p ≤ 0.033), who had no food handling and preparation training ( p ≤ 0.005), poor personal hygiene ( p ≤ 0.0001), who had not taken regular medical checkup ( p ≤ 0.008), and whose nail was not trimmed ( p ≤ 0.0001). The most abundant intestinal parasite identified was G. lamblia (24, 26.7%) followed by E. histolytica/dispar (22, 24.4%), and A. lumbricoides (15, 16.7%). Twenty-eight (45.2%) study individuals were also found with mixed infections. The study thus revealed a high prevalence of intestinal parasitic infection among apparently healthy food handlers in food establishments of the study area. Mass drug administration for all food handlers working in food establishment areas of the town coupled with health education and training should be initiated urgently.

“…Moreover, methodological differences such as study group, sample size, diagnostic method used might contribute for this difference. The current finding is in line with a study conducted in Ethiopia 44.6% [ 47 ].…”

“…This study showed that fingernail status had statistically significant association with the prevalence of intestinal parasitic infections AOR: 1.09 (95%CI: 0.53, 2.23). This finding was in line with a meta-analysis study conducted among primary school children in Ethiopia [ 43 , 44 , 47 ].…”

“…However, in contrary to this result, A. lumbricoides infection was found to be higher among children aged > 10 years reported from the Philippines 14 . The other justification for the higher prevalence of A. lumbricoides in the study area is could possibly be the humid climatic condition and clay nature of the soil which is favorable for the ova to survive longer 18 .…”

Food hygiene practices and determinants among food handlers in Ethiopia: a systematic review and meta-analysis

“…Poor food hygiene practices primarily exacerbate food-borne illness transmission [ 29 – 32 ]. Previous studies showed inconsistent good food hygiene practices among food handlers in Ethiopia, ranging from 19.4 to 90.4% [ 33 – 36 ]. On the other hand, knowledge, attitude, training on main food hygiene components, and routine medical checkups of food handlers were some of the factors associated with good food hygiene practices [ 34 , 37 , 38 ].…”
