Objective To explore reasons for high rates of unintentional poisoning amon
g Latino children under 5 years old. Design Ethnographic interviews were ca
rried our using a sample of mothers identified via door-to-door canvassing
in an area with documented high injury rates among Latino children. Intervi
ews included many open-ended and follow-up questions to elicit a detailed f
amily history and emphasized observation of conditions and behaviors in the
homes. Setting Low-income neighborhoods of Southern California. Subjects F
ifty mothers born in Mexico with children under 5 years old. Results Childr
en were exposed to potential poisoning agents in more than 80% of homes. Co
ntributory factors related to culture included favorable attitudes toward i
ron as a healthful substance; extensive use of products that lack child-res
istant packaging, such as rubbing alcohol and medicines from Mexico; high p
revalence of shared housing; limited familiarity with toxic household chemi
cals not widely used in Mexico; and inability to read warning labels in Eng
lish. Conclusion Current Poison Control Center outreach efforts should be e
xpanded. Clinicians are uniquely positioned to advise patents about the saf
e use and storage of toxic substances, including widely used products lacki
ng child-resistant packaging. Medicines should be labeled in Spanish for th
ose who do not know English.
