Panelists talked about a number of challenges related to food production in Texas and the Gulf Coast. One scientist noted that more than 10,000 seafood specimens were tested from state territorial and federal waters that were impacted by the oil spill. Waters were not reopend for fisheries harvest until oil had dissipated and testing showed that seafood was safe for consumption. The samples that did contain measurable residues were consistently 100 to 1000-fold below levels of concern established in the uniform seafood safety protocol. According to another panelist, there are an estimated 10,000–20,000 cases of physician diagnosed pesticide poisoning among agricultural workers each year in the US. Many more cases are likely to go undiagnosed because symptoms can be flu-like and non-specific, or the farmworkers lack access to healthcare. In a recent study of adolescent farmworkers from Texas, only 21% had ever received any training in pesticide safety. Another major health concern relates to occupational heat stress. Dr. Jeffrey Levine reported that from 1992–2006 there were 423 occupational heat-related deaths in the US. The mortality rate from occupational heat-related illness among crop workers was nearly 20 times as high as for all industries during that time frame. More than 150 attendees attended the session which was chaired by Laura Plunkett of Integrative Biostrategies and Erica Bruce of Baylor University.
