Shrimp fry collectors, including children, face threats to their safety as a result of working in the Bangladeshi Sundarbans area, a large, continuous area of salt-tolerant mangrove forests. A study of two villages undertaken by the Bangladeshi National Center for Biotechnology Information (NCBI) found that wild animals including estuarine crocodiles, bull sharks and Bengal tigershad killed 111 people from just two villages in the Sundarbans. Of these attacks, fry collectors represented nearly 25 percent of all victims and half of all women attacked by animals. Snakes also pose a danger for Bangladeshi fry collectors, especially in coastal Barisal and Khulna divisions. Fry collectors, and especially women and children, are also at danger of drowning due to tidal currents. They are at particularly high risk because larvae concentration is at its highest during full moon periodsperiods when rivers rise and currents increase. According to a 2008 study of three districts in the Greater Khulna region of Bangladesh Satkhira, Bagerhat and Jessorewomen working in shrimp processing factories are also vulnerable to a range of occupational hazards. These included fungal infection in their hands, colds, severe muscle strain and back pain, eye irritation, stomach-related illnesses, cuts and bruises. Workers reported hand infections so severe that they were unable to eat with their hands. One woman described her experience: After working non-stop for long, 12-13 hours, we become tired, sick and exhausted. The buckets for the shrimp are so cold that our hands get frozen. We all have fungal infections. Although HAACP training modules recommend the use of gloves, some female workers and managers reported that women chose not to wear gloves because they slow down the work and impact their piece-rate determined earnings. Other workers reported that they were not given gloves.
