Two days after arriving at a temporary migrant shelter on the border with the United States in June, Rosa Viridiana Ceron Alpizar’s 9-year-old daughter and 1-year-old son fell ill. Most of the children in the converted gymnasium had stomach problems after being given a meal of sausages and beans, she recalls. Alpizar’s daughter improved rapidly, but her son did not.
