Pools of water on the floor and old, hard-to-clean equipment at a Colorado farm's cantaloupe-packing facility were probably to blame for the deadliest outbreak of foodborne illness in 25 years, the Food and Drug Administration said Wednesday. 
  
 Government investigators found positive samples of listeria bacteria on equipment in the Jensen Farms packing facility and on fruit that had been held there. 
  
 In a six-page assessment of the conditions at the farm based on investigators' visits in September, the FDA said Jensen Farms had recently purchased used equipment that was corroded, dirty and hard to clean. The packing facility floors were also constructed so they were hard to clean, so pools of water potentially harboring the bacteria formed close to the packing equipment. 
  
 The dirty equipment _ purchased in July, the same month the outbreak started _ was previously used to wash and dry potatoes, the agency said, and the listeria "could have been introduced as a result of past use of the equipment," according to the report. 
  
 FDA officials said that they are not concerned about similar listeria contamination in the potatoes that were previously processed on the equipment because those vegetables are rarely eaten raw. Cooking can kill the bacteria. 
  
 A warning letter from the agency to Jensen Farms said that a third of 39 swabs taken throughout the facility tested positive for listeria. 
  
 "This significant percentage of swabs that tested positive for outbreak strains of (listeria) demonstrates widespread contamination throughout your facility and indicates poor sanitary practices in the facility," the letter said. 
  
 Though the agency said the contamination likely happened in the packing house, the way the cantaloupes were cooled after being picked may have exacerbated the listeria growth. The farm did not use a process called "pre-cooling" that is designed to remove some condensation, thus creating moist conditions on the cantaloupe rind that are ideal for listeria bacteria growth. Listeria grows in cool environments, unlike most pathogens. 
  
 FDA said that samples of cantaloupes in Jensen Farms' fields were negative for listeria, but bacteria coming off the field may have initially introduced the pathogen into the open-air packing house, where it then spread. Listeria contamination often comes from animal feces or decaying vegetation. 
  
 Another possible source of contamination was a truck that frequently hauled cantaloupe to a cattle operation and was parked near the packing house. Contamination could have come from the cattle operation and then tracked into the house by people or equipment, the report said. 
  
 The Centers for Disease Control and Prevention says 123 people have been sickened in the outbreak, including the 25 who died. It is the deadliest known outbreak of foodborne illness in the U.S. since an outbreak of listeria in Mexican-style cheese in 1985. 
  
 The tainted fruit, which Jensen Farms recalled in mid-September, should be off store shelves by now. But the number of illnesses may continue to grow _ symptoms of listeria can take up to two months to appear. Barbara Mahon of the CDC said that the illnesses peaked from mid-August through September, but that the government would continue to monitor the situation for at least another two weeks. 
  
 The CDC on Tuesday confirmed a sixth death in Colorado and a second in New York. Indiana, Kansas, Louisiana, Maryland, Missouri, Nebraska, New Mexico, Oklahoma, Texas and Wyoming have also reported deaths. 
  
 FDA officials said Wednesday that the agency has never visited the farm to do an inspection. But that would likely change under a new food safety law signed by President Barack Obama earlier this year that boosts the number of inspections the FDA conducts annually. Currently, the agency may only visit a food facility every five or 10 years, at the most. 
  
 FDA officials said they have visited many food facilities over the years and the conditions at Jensen Farms were unique. 
  
 "There is no reason to believe these practices are indicative of practices throughout the industry," said Sherri McGarry, a senior officer in FDA's office of foods. 
  
 McGarry said the agency is still considering what enforcement actions it will take. Officials said the farm had cooperated in all aspects of the recall and investigation. 
  
 Messages left for the farm's owners were not immediately returned. 
  
 Listeria is rare but more deadly than well-known pathogens such as salmonella and E. coli. While most healthy adults can consume listeria with no ill effects, it can kill the elderly and those with compromised immune systems. The CDC said the median age of those sickened is 78, and most ill people are over 60 years old. 
  
 It is also dangerous to pregnant women because it easily passes through to the fetus. CDC said it is aware of one miscarriage associated with the outbreak and four illnesses total associated with pregnancy. One newborn was born with listeria infection. 
  
 Symptoms include fever and muscle aches, often with other gastrointestinal symptoms.

 In a report released Wednesday, the Food and Drug Administration cited multiple problems at the Jensen Farms facility in Holly, Colo., some of which could suggest how listeria came to enter the farm's packing shed. 
  
 For instance, FDA officials said, a truck used to take waste cantaloupes to a nearby cattle farm was parked next to the open-air packing shed. Because cattle are known carriers of the listeria bacteria, manure carried on the truck's wheels could have contaminated the area around the packing facility. 
  
 Other problems found included: 
  
 •Equipment used to wash and dry the cantaloupe was impossible to clean thoroughly and had built-up dirt on it. 
  
 •A refrigerator drain line allowed water to pool on the floor next to the packing equipment. 
  
 •The floor of the packing shed was constructed such that it was very difficult to clean. 
  
 •The company had purchased a used potato-washing machine to clean its cantaloupes, which may have been another way that listeria was introduced to the facility. 
  
 •The cantaloupe, which typically come in from the fields at 80 degrees, were not pre-cooled to inhibit bacteria growth before being placed in cold storage. This could have created conditions that allowed for condensation, an environment ideal for growth of listeria. 
  
 The outbreak is now one of deadliest of listeria in the USA. The deadliest known was in 1985 when a Mexican-style soft cheese contaminated with listeria from Jalisco Products killed 18 adults and 10 newborns, as well as caused 20 miscarriages, according to the Centers for Disease Control and Prevention. It sickened 142 others. 
  
 This outbreak has been linked to Rocky Ford-brand cantaloupes sold by Jensen Farms. The cantaloupes were recalled Sept. 14, and no melons under the recall should still be on store shelves. Most of the contaminated melons should be out of the food supply by now. The CDC and the FDA said any cantaloupes not from Jensen Farms are safe to eat. 
  
 Symptoms of listeriosis can take up to two months to develop in someone who has eaten contaminated food, so illnesses could continue to show up into November, the CDC said. 
  
 FDA officials announced the results of their findings today at a news conference in Washington D.C. The inspections at the farm, which included staff from FDA and Colorado state officials, took place on Sept. 10. 
  
 They took 39 environmental samples from the facility, mostly swabs of surfaces. No samples from the fields were positive for the outbreak strains, but 12 from the packing facility were. 
  
 Armed with those findings, FDA inspectors returned to the farm on Sept. 22 and 23 and conducted further inspections, where they found the problems listed above. The firm cooperated with the inspections. 
  
 Consumers shouldn't be concerned about cantaloupe in general, says Sherri McGarry, an adviser to FDA's Coordinated Outbreak Response and Evaluation team. 
  
 "We want to emphasize that there's no reason to believe that these factors are indicative of practices through the industry," McGarry said. "I'd say that they were fairly unique." 
  
 Jim Gorny, FDA's senior adviser for produce safety, said that the conditions found at Jensens Farms were not normal for other cantaloupe facilities. |||||

Federal health inspectors discovered listeria inside the packing facility of the Colorado farm that shipped out lethal cantaloupes, killing 25 people so far, reports USA Today. FDA officials also found several sanitation problems, including dirty and contaminated equipment that could explain how listeria spread to the fruit. For example, a truck that ferried waste cantaloupes to a cattle farm was parked near the open-air packing facility. Cow manure on the wheels could have infected the produce, say officials. Other violations at Jensen Farms included pools of water on the floor and a dirty potato-washing machine (for the cantaloupes) that could have introduced listeria into the facility. The farm bought the hard-to-clean washer in July, the same month the outbreak started, notes AP.
