Some travelers are willing to risk disease to experiment with local cuisine.
Others prefer to avoid potential sources of infection at all costs. Chemical contamination with pesticides or poisons is not removed by boiling or disinfecting. All raw food is subject to contamination, either through contact with contaminated water, fecal fertilizers, or dirty hands or utensils. Travelers should consider avoiding salads, uncooked vegetables, unpasteurized milk and milk products, such as cheese. Of note, certain fruits such as watermelon are subject to concern as they may be injected with contaminated water to increase their weight at market.
