Parents’ knowledge,behaviour and concerns of food chemical hazards: Korean mothers sending their preschool‐aged children to child care centres

Although incidences of foodborne illness caused by chemical hazards are increasing, the studies on public awareness of food chemical hazards are limited. This study was conducted to assess mothers’ knowledge, behaviour and concerns on diverse food chemical hazards. A total of 960 mothers sending their preschool‐aged children to child care centres in Gwanak‐Gu, Seoul, Korea were surveyed, and 633 (65.9%) returned the questionnaires. After excluding inappropriate questionnaires, 364 (37.9%) were analysed. The majority of the mothers were able to identify food categories containing acrylamide (83.2%) and trans fat (80.2%), while slightly over half of the mothers named food categories containing allergen (56.3%) or pesticide residues (57.1%). Less than two thirds of mothers were knowledgeable of human exposure pathway to environmental contaminants (59.3%), acrylamide (55.2%) or heavy metals (65.9%). A significant number of mothers showed familiarity on health risk from dietary exposure to environmental contaminants (82.4%), trans fat (91.5%) or heavy metals (96.7%) (P < 0.05). The data on safe food behaviour towards environmental contaminants (81.8%), acrylamide (98.0%), heavy metals (96.7%) and trans fat (90.6%) showed high levels of right behaviours. About 47.2% and 22.8% of mothers read label of food additives and ingredient statement on allergen when purchasing processed foods, respectively. Mothers seemed to be concerned about food chemical hazards. Among the sociodemographic characteristics, only age significantly differentiated mothers’ concerns on chemical hazards in foods (P < 0.05). This study suggests that mothers needed to be educated on food chemical hazards regardless of their education levels, occupation status or the number of child.
