Rather, it reflects problems with our agricultural system and growing failures in food safety. <\/p>\n<p>How Is Produce Grown, Harvested And Processed?<\/p>\n<p>We rely heavily on irrigation systems. A 2023 Irrigation and Water Management Survey found that <a class=\"color-link\" href=\"http:\/\/www.ers.usda.gov\/topics\/farm-practices-management\/irrigation-water-use#\" target=\"_blank\" rel=\"nofollow noopener noreferrer\" data-ga-track=\"ExternalLink:http:\/\/www.ers.usda.gov\/topics\/farm-practices-management\/irrigation-water-use#\" aria-label=\"45% of all water used as irrigation came from surface water\u2060\">45% of all water used as irrigation came from surface water\u2060<\/a>.<\/p>\n<p>This is important because surface water can be easily contaminated, and it doesn\u2019t take many organisms to cause infection. <a class=\"color-link\" href=\"https:\/\/blog-fruit-vegetable-ipm.extension.umn.edu\/2023\/06\/are-you-using-surface-water-to-irrigate.html#\" target=\"_blank\" rel=\"nofollow noopener noreferrer\" data-ga-track=\"ExternalLink:https:\/\/blog-fruit-vegetable-ipm.extension.umn.edu\/2023\/06\/are-you-using-surface-water-to-irrigate.html#\" aria-label=\"Contamination can occur from leaking septic and sewer systems, and from people\u2019s waste\">Contamination can occur from leaking septic and sewer systems, and from people\u2019s waste <\/a>and garbage\u2060. The Food Safety Modernization Act also allows growers to harvest produce up to four days after water is applied\u2014giving any contaminants a chance to multiply. <\/p>\n<p>We need to examine all points in the chain, from the field to the final purchase, where contamination might occur. <\/p>\n<p>Farm Workers<\/p>\n<p>Most of our produce is grown and harvested by migrant farm workers. We should be looking at how they are treated and what their working and living conditions are like.<\/p>\n<p>Amy Liebman, MPA, is the chief program officer for <a class=\"color-link\" href=\"https:\/\/www.migrantclinician.org\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer\" data-ga-track=\"ExternalLink:https:\/\/www.migrantclinician.org\/\" aria-label=\"Migrant Clinicians Network\">Migrant Clinicians Network<\/a>. She explains that some of the problem traces back to the workers \u201cbeing vulnerable to infectious diseases because of their living situation,\u201d which they have little control over.<\/p>\n<p>Employer-provided housing is generally crowded; there is often poor sanitation. Drinking water may come from springs or wells. While wells are monitored before people move in, there is no requirement to check them again\u2014leaving the risk that contamination could go undetected indefinitely. <\/p>\n<p>When working in the fields, workers are supposed to be given water and bathroom breaks, particularly in the heat. Complaints of not being allowed adequate breaks are common.<\/p>\n<p>The Occupational Health and Safety Administration mandates that there be <a href=\"https:\/\/www.migrantclinician.org\/files\/Field%20San%20Guide.pdf\" target=\"_blank\" rel=\"nofollow noopener noreferrer\" data-ga-track=\"ExternalLink:https:\/\/www.migrantclinician.org\/files\/Field%20San%20Guide.pdf\" aria-label=\"one toilet and one hand-washing facility for every 20 workers\">one toilet and one hand-washing facility for every 20 workers<\/a> and that these facilities be within a quarter-mile of each worker. But who is monitoring? <\/p>\n<p>Liebman emphasizes, \u201cI don\u2019t think it\u2019s the farm worker that is at the center of this. I think it has more to do with the crops being contaminated from other sources like irrigation water and then how we process and package our food.\u201d She also speaks about \u201cthe fear that\u2019s percolating through this population,\u201d noting \u201cworkers being afraid to report anything, fear of losing their job, and fear of being deported.\u201d <\/p>\n<p>The farm workers aren\u2019t provided with sick leave or with reliable access to medical care. Thus, they are the initial victims in this disaster, because of the conditions they are forced to work and live under. They are the proverbial \u201ccanaries\u201d in this growing public health crisis.<\/p>\n<p>Our Faltering Food Safety Systems <\/p>\n<p>The greater failure is the growing lapses in food safety monitoring, with responsibilities divided among several agencies.<\/p>\n<p>As many know, the Department of Government Efficiency initiated huge cuts to federal agencies.

For example, sewage or septic system failures can contaminate a field or a processing plant. Because of the size of the outbreak, she hypothesizes that either contaminated irrigation systems or water used in processing will likely be the source of the problem.<\/p>\n<p>She also notes how much reporting, particularly from the CDC, is lagging, because \u201cNo one\u2019s manning the boat.\u201d Or, she adds, \u201cMaybe there\u2019s one person who\u2019s manning 50 boats instead of the one boat they had before.\u201d She concludes, \u201cWe\u2019re just going to see more and more of these things, and bigger than they have ever been in the past, and delays that could have stopped things sooner. It will just make it all worse.\u201d<\/p>\n<p>Besides the dismantling of safety systems through cuts and restructuring from the Trump administration and DOGE, Liebman emphasizes the personal policy changes. She concluded, \u201dI think from a public health perspective, our immigration policies are making it more dangerous\u2014not just for the workers themselves, but for our community.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"SALINAS, CALIFORNIA &#8211; MARCH 10, 2023: During a break in the rain farm workers drain lettuce fields of&hellip;\n","protected":false},"author":2,"featured_media":53310,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[4],"tags":[9268,16375,28950,3505,14175,8,28133,28951,9,9542,16985,7,3070],"class_list":["post-53309","post","type-post","status-publish","format-standard","has-post-thumbnail","category-top-stories","tag-administration","tag-centers-for-disease-control","tag-cyclospora-outbreak","tag-doge","tag-food-and-drug-administration","tag-headlines","tag-lettuce","tag-migrant-farm-worker","tag-news","tag-produce","tag-sanitation","tag-top-stories","tag-water"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@news\/116931247970096091","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/news\/wp-json\/wp\/v2\/posts\/53309","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/news\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/news\/wp-json\/wp\/v2\/comments?post=53309"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/news\/wp-json\/wp\/v2\/posts\/53309\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/news\/wp-json\/wp\/v2\/media\/53310"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/news\/wp-json\/wp\/v2\/media?parent=53309"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/news\/wp-json\/wp\/v2\/categories?post=53309"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/news\/wp-json\/wp\/v2\/tags?post=53309"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
