Sounds grand, but, as of 2016, there’s actually only one person there, and, that’s only part of her work: she also has to do work for the University of Georgia.</p> <p>The NCHFP acts as the hub of a wheel.</p> <p>The spokes of a wheel are the ‘Extension Services’ at universities in various states. These Extension Services act as knowledge transfer agents, to ensure that knowledge from the academic world is transferred in an applied, practical way out into the surrounding world.</p> <p>The USDA directs funds to help with home canning through these Extensions. These would be people who are part-time, or, whose full-time job is actually something else, with just a portion of their work week or year being funded for home canning matters. We’re never seen a tally on how many funded or partially funded positions per University Extension, but it’s likely less than a handful per.</p> <p>The funding for all parts of the wheel is bare bones.</p> <p>So, when in the canning world we talk about the “USDA”, we are talking about a network consisting of a small handful of people who, like Mulder and Scully in the X-files, care passionately about a small field that everyone else in the massive mother organization likely thinks is “weird”, so they are relegated to the “basement office” with hand-me-down furniture and a bare trickle of funding to make sure the lights come on when they flick the switch in the mornings. There are likely many community centres, golf clubs and parish church offices that have greater and more secure funding to work with than these people do.</p> <p>Still, Americans need to be grateful: America is the only country in the world that funds any knowledge transfer at all like this for home canning.</p> <p>In any event, when home canners refer to “USDA canning people”, these are the people they mean.</p> <p>The USDA never approves canning-related products or supplies. They will cite products as an example. And, they will positively recommend FOR practices, procedures and principles. And rarely, come out and explicitly recommend AGAINST something. (See <a href="https://www.healthycanning.com/usda-recommendations-for-and-against">USDA Recommendations for and against</a> .)</p> <h2><span id="The_USDA_canning_people_would_probably_love_to_spend_more_time_researching_the_questions_we_have">The USDA ‘canning people’ would probably love to spend more time researching the questions we have</span></h2> <p>These “USDA canning people” are caught in the middle, and probably frustrated. Under-staffed and under-resourced, they scramble to answer questions from 300 million Americans and keep them from wiping out their churches and neighbourhoods with botulism from using 70 year old canning books with dangerously out-dated advice.</p> <p>At the same time, some home canners criticize them for being “behind on consumer demands” and not having researched more pressure canning recipes using tofu and soy milk to keep up with changing tastes and changing times.</p> <p>The “USDA people” would probably love to research a lot more things such as that, and faster too (even if people didn’t always like the answers.) They probably would have loved to get an answer out about steam canning decades ago. Finally approved in 2015, it had been a question since at least the 1920s, according to Elizabeth Andress. <span class="footnote_referrer"><a role="button" tabindex="0" onclick="footnote_moveToReference_1248_1('footnote_plugin_reference_1248_1_2');" onkeypress="footnote_moveToReference_1248_1('footnote_plugin_reference_1248_1_2');"><sup id="footnote_plugin_tooltip_1248_1_2" class="footnote_plugin_tooltip_text">[2]</sup></a><span id="footnote_plugin_tooltip_text_1248_1_2" class="footnote_tooltip"> Andress, Elizabeth L and Gerald Kuhn.

The great body of the home canning research that we work from today was done with a small investment from the government in the 1940s — particularly 1943 to 1946, when food was used as a war weapon by the Allies. Most people would argue that that was a very good use of tax-payers’ money: in the decades since, it has generated and continues to generate a massive return on investment in terms of social capital, household economy, and population health. Very little if any of government money spent in any of the decades since then is still delivering such a return, let alone any return at all.</p> <p>While many home canners criticize the ‘USDA people’ for not keeping up, it’s possible we all keep missing the clues they have been trying give us. Those people obviously can’t say in public, “tell our USDA bosses at the top to give us a bit more money to research some of this stuff you guys want.” They’d get a strip torn out of them, and maybe lose their jobs. Instead, they say things such as “Currently we have no recommendation for doing that and currently there is no funding to research it.” That’s probably as clear as they dare to say, “we’d love to but we don’t have the funding — <em>but you could tell your elected representatives you want that situation to change</em>.” But home canners seem to get angry with them for the first part of that sentence, and not twig to the pretty clearly implied second part.</p> <h2><span id="The_USDA_is_considered_the_leading_expert_in_home_canning">The USDA is considered the leading expert in home canning</span></h2> <p>The USDA is considered the leading expert in home canning by both the private and public sector.</p> <p>Outside of America, the USDA’s home canning knowledge is also very widely respected, and is cited as the international authoritative source on home canning.

Home canning is an evolving science, and, by virtue of minimal funding to the USDA’s home canning research area for the past several decades, their research in some aspects may now well lag behind more current science-based findings out there in the field by industry and private-sector partners such as the Jarden home canning companies. As a home canner, when trying to identify what qualifies as a <a href="https://www.healthycanning.com/reputable-sources-for-home-canning-information/">reputable source for home canning information</a>, just be sure to verify that a source can point to science-based, lab-tested research results to back up their information.</p> <h2><span id="USDA_Extension_Agents">USDA Extension Agents</span></h2> <p>The people that the USDA helps fund at various University Extensions across the country are often referred to as “Extension Agents.”</p> <p>Some of these people can sometimes tend to be very conservative in their advice.

They are sometimes be a bit behind in their knowledge, too: in 2016, many are still saying that <a href="https://www.healthycanning.com/steam-canning">steam canning</a> is “not recommended” (It was in fact <a href="https://nchfp.uga.edu/publications/nchfp/factsheets/steam_canners.html" target="_blank" rel="nofollow noopener">approved by the National Center in June 2015</a>), and are saying that heritage tomatoes are more acidic than modern tomato varieties.</p> <p>A few are scientists and seem to be lucky enough to actually get some funded time to keep up with the latest news and even help move things forward. Most though appear to be educators who may be so run off their feet educating that they don’t always have time to keep up with the latest and greatest.</p> <p>Rick Heflebower and Carylyn Washburn, professors at Utah State, explain:</p> <blockquote><p>Extension agents are educators by profession. Their mission is to teach ‘research based’ methods to the public. For various reasons, rumors or opinions are spread around as though they are truth, such as the notion that ‘older tomato varieties are more acidic than newer hybrids’ and therefore safe to can without acidifying agents. In our study, the tendency was for the older varieties to be less acidic than the hybrid we compared them to. Advice is sought from Extension agents each season regarding which tomato varieties to grow successfully and how to safely process them. We feel that it is important for Extension agents to promote the current USDA recommendations and to understand them well enough to advise others.” <span class="footnote_referrer"><a role="button" tabindex="0" onclick="footnote_moveToReference_1248_1('footnote_plugin_reference_1248_1_5');" onkeypress="footnote_moveToReference_1248_1('footnote_plugin_reference_1248_1_5');"><sup id="footnote_plugin_tooltip_1248_1_5" class="footnote_plugin_tooltip_text">[5]</sup></a><span id="footnote_plugin_tooltip_text_1248_1_5" class="footnote_tooltip">Heflebower, Rick and Carylyn Washburn.

Anyone used to today’s modern 190% “safe and sound” guarantee from USDA home canning recommendations would fall out of their seats reading that. It would absolutely not be acceptable; people wouldn’t stand for it.</p> <p>A USDA scientist, Charles Ball, in 1927 summed up the USDA’s approaches as being “cut and try”: keep canning something with different processing times until it stopped going bad in the jars. (For more detailed information, see <a href="https://nchfp.uga.edu/publications/usda/review/earlyhis.htm" target="_blank" rel="nofollow noopener">Early History of the USDA</a>.)</p> <p>During the war, with shortages of proper equipment, some extension agents tried to be helpful by suggesting very long boiling water processing times for foods that the USDA overall already knew had to be pressure canned instead to be safe. And people got sick.</p> <p>Those days of trying to be helpful, with not very good results, are long gone.</p> <p>They wouldn’t get any thanks anyway, if their guess happened to be right. And if they were wrong, they’d be in a lot of trouble legally these days, and the people involved in the guess would lose their jobs. So there is just plain no upside in a guess for them.</p> <p>Besides that, they are too dedicated professionally to their field to do something as risky as guessing, regardless of the upside or downside. Their stance on canning plain cabbage from the National Center’s blog sums it up:</p> <blockquote><p>“… we do not just guess at a process time – the risk is too great.

They want to promote their methodology over the USDA’s:</p> <blockquote><p>The USDA doesn’t trust home-canners to do things right, and so their way to compensate for it is to tell you to cook the hell out of everything — and it produces low-quality canned goods…The USDA will tell you to never use an heirloom recipe.

There are people who say they are happy to <em>and do</em> follow the recommendations, but who would still just like to know the <em>why</em>. The old school USDA approach since World War Two, they feel, has been very much school marm: never mind the why, just do as you’re told. This has had the effect of getting Americans’ backs up, and Americans historically have never been at their most cooperative in such a condition. It has also had the effect of causing people to do internet searches on the “why”, and they often find dangerous, conflicting advice as part of the answer.</p> <p>Part of the reason for the lack of detailed reasons behind directions is surely a simple lack of time: there are so few people actually working in home canning for the USDA that they barely have time to find and hand you the right recipe from the store chest of tested recommendations and recipes that they have to work from, let alone sit down with you and go over it, as there can be 500 other new email queries to answer that day.</p> <p>The underlying issue, though, might be that original writers of those recipes and recommendations did not take the time, or feel it necessary, to separate out quality versus safety reasons in the directions. For instance, the canning recipes for tomatoes all direct you to peel the tomatoes first. Was that just a personal preference of the original recipe writer? Turns out, <a href="https://www.healthycanning.com/peeling-tomatoes/">peeling tomatoes for home canning is a safety reason</a>. But the directions don’t say.</p> <p>One blogger writes,</p> <blockquote><p>The USDA has done a tremendous amount of research on home canning. They do not approve or disprove anything but rather make recommendations based on the results of their research. They may not recommend using a certain ingredient (eg. corn starch) or canning a certain food (eg. broccoli) because the resulting quality is less than acceptable. They may not recommend canning a certain food (eg. thickened stew, pureed pumpkin) because it presents a safety issue as the heat cannot penetrate to the centre of the jar to ensure a safe product. The problem is, the USDA does not disclose whether their recommendation is based on safety <em>or</em> quality.” <span class="footnote_referrer"><a role="button" tabindex="0" onclick="footnote_moveToReference_1248_1('footnote_plugin_reference_1248_1_9');" onkeypress="footnote_moveToReference_1248_1('footnote_plugin_reference_1248_1_9');"><sup id="footnote_plugin_tooltip_1248_1_9" class="footnote_plugin_tooltip_text">[9]</sup></a><span id="footnote_plugin_tooltip_text_1248_1_9" class="footnote_tooltip"> <span class="footnote_url_wrap">https://momskitchencooking.blogspot.ca/2013/10/where-are-canning-police-when-you-need.html#sthash.6HzkQSLS.dpuf</span> </span></span><script type="rocketlazyloadscript" data-rocket-type="text/javascript">window.addEventListener('DOMContentLoaded', function() { jQuery('#footnote_plugin_tooltip_1248_1_9').tooltip({ tip: '#footnote_plugin_tooltip_text_1248_1_9', tipClass: 'footnote_tooltip', effect: 'fade', predelay: 0, fadeInSpeed: 200, delay: 400, fadeOutSpeed: 200, position: 'top right', relative: true, offset: [10, 10], });});</script></p></blockquote> <p>At various times in the past, USDA educators have tried to help people being understand the reasons behind canning recommendations:</p> <p>In 1921, a USDA writer wrote:</p> <blockquote><p>“SUCCESS in home canning depends a good deal on how well the canner understands the ‘why’ of each step in the method.

Some people feel that rather than make that quality decision themselves, which can be subjective (for instance, some people love canned turnip, others do not), that the USDA should have released the processing times to people with an advisory about quality, and let people decide themselves.</p> <p>Healthy Canning isn’t currently aware of the USDA having any such completed and safe-but-dubious-quality testing results they are holding back on. Ball, however, does: Ball had and then withdrew in 1977 canning advice for broccoli, Brussels sprouts, cauliflower, celery, and cabbage. Previous to withdrawing those canning recommendations Ball had warned about quality. If you are interested in the reason for the withdrawal, it’s Ball you would need to ask: the USDA never had issued canning recommendations on those products.</p> <h2><span id="Is_the_USDA_too_strict">Is the USDA too strict?</span></h2> <p>One criticism often levelled at the USDA is that they are too strict.

Done incorrectly, a hostess could be serving up a trip to the hospital when she puts last fall’s spaghetti sauce on her table.</p> <p>Illness stemming from eating home canned food is unnecessary, and researchers at Pennsylvania State University — considered the leading authorities in the field of understanding home preservation — are striving to do away with the outdated and unsafe methods of food storage and preservation that cause it.</p> <p>Because of its recognized leadership, the University’s Food Science Department has been awarded a five-year grant to establish the first Home Food Preservation Center of Excellence in the United States. Funding to operate the center totals $80,000 for the first year, and more than SHW, (HH) in each of the next four years. It was jointly offered by the U.S. Department of Agriculture’s Extension Service, Cooperative State Research Service and Agricultural Research Service. “It is an awesome responsibility in terms of the services we will be asked to perform.” says Gerald D. Kuhn, professor of food science and project leader. “We will have this become the national base of information for our peers, and for consumers, through the extension service.”</p> <p>Kuhn says Penn State began studying home preservation techniques in the mid-1970s, when home canning regained popularity after it was lost as a family art in the 1950s. “Valuable publications on the matter ceased in the ‘50s.” he says. Interest died off until 1975, when the energy crisis took hold and gardening became popular again. Gardeners renewed interest in preserving their harvests. However, the methods the preservers were using were suspect.</p> <p>” Anything is safe — put it in a jar and put a lid on it,” Kuhn explains is the concept many preservers were using. This naturally led to outbreaks of bacterial problems and increased cases of botulism. “We still have outbreaks of botulism.” he says.</p> <p>“Many changes have occurred during the last 20 years in terms of horticultural varieties, canning ingredients, equipment, home kitchens, lifestyles and preferences for foods.” Kuhn says. That is what the Penn State Center of Excellence team will be studying.</p> <p>Working with Kuhn are Dr. Sudhir Sastry, assistant professor of food engineering; Dr. Stephanie Doores, assistant professor of food science; Elizabeth Andress, research assistant; and Thomas Dimick, senior research technician.</p> <p>The team currently is working on venting practices and how they alter heat penetration, as well as a jar lid evaluation. In the summer, as the center is moved into its own facility and receives its computerized data acquisition system, the team will study several priority issues in the field, Kuhn says.</p> <p>The team will review equipment, including dial and weighted pressure gauges, and the use of pressure cookers, as well as the reevaluation and establishment of processes for various foods which need new data bases. Kuhn says. The foods cover a wide range, and include asparagus, spinach, corn, peas, ground meat, heart, tongue, soup stock, rabbit, all forms of tomato products and combination products.</p> <p>Miscellaneous projects will include special diet requirement foods, pie fillings and seafoods, such as salmon and tuna, Kuhn says. Future work may focus on new equipment, such as microprocessor-controlled canning.</p> <p>For now the center is focusing on canning, but may expand to study freezing, drying and pickling techniques. Andress, who with Kuhn organized a graduate-level seminar for extension personnel held at The Louisiana State University last year, says that each state issues pamphlets defining safe canning procedures, and “there is a lot of variety among them. A center can alleviate that problem.”</p> <p>Dr. Sastry adds that the center can become a source of data for the industry and the consumer: “We should be influencing all recommendations being made by the U S. Department of Agriculture,” he says.</p> <p>Kuhn says the equipment companies are looking to Penn State as a source of unbiased information. “Our name may not be on it, but it is likely that it began here,” he says of new advances in equipment for home canners.</p> <p>The team recognizes that one of its hardest tasks may well be convincing people that what they learned at “grandmother’s knee” may not be the safest method to use. “We still have many doubters but we hope that will continue to change,” he said. <span class="footnote_referrer"><a role="button" tabindex="0" onclick="footnote_moveToReference_1248_1('footnote_plugin_reference_1248_1_23');" onkeypress="footnote_moveToReference_1248_1('footnote_plugin_reference_1248_1_23');"><sup id="footnote_plugin_tooltip_1248_1_23" class="footnote_plugin_tooltip_text">[23]</sup></a><span id="footnote_plugin_tooltip_text_1248_1_23" class="footnote_tooltip"> Altoona Mirror.

The USDA has offered home canning and other home food preservation recommendations since the early 1900s. By the end of the century, it was time to review what was available. Extension agents on faculty at the University of Georgia applied for and received two grants that ran five years to cover the topic. “We were asked to do a literature review of a lot of the research that happened since the last major work at USDA, and determine some needs to do some more product development for their canning guides,” said Elizabeth Andress, professor and Extension Food Safety Specialist. “We developed probably 30-plus new canning recommendations, and we produced a video series. We produced the website, and the offerings on that include a free online course, and various outreach methods to help get out information from the USDA recommendations, also.” <span class="footnote_referrer"><a role="button" tabindex="0" onclick="footnote_moveToReference_1248_1('footnote_plugin_reference_1248_1_25');" onkeypress="footnote_moveToReference_1248_1('footnote_plugin_reference_1248_1_25');"><sup id="footnote_plugin_tooltip_1248_1_25" class="footnote_plugin_tooltip_text">[25]</sup></a><span id="footnote_plugin_tooltip_text_1248_1_25" class="footnote_tooltip"> Halloran, Amy. <a href="https://www.foodsafetynews.com/2011/04/gardening-is-back-and-canning-wont-be-far-behind/#.VO6ynS5Ciq8" target="_blank" rel="noopener">Preserving the Art of Canning Safely at Home</a>.

It understood that heat was required for sterilization, and worked with two heat sterilization methods. The bulletin recommended sterilizing jars by “fractional sterilization”: boiling the jars for an hour a day for two or three successive days. The first day killed moulds and most bacteria, but left the spores. The second and third days would in theory kill the spores that germinated as the jars cooled down after the first boiling. The alternative second heat sterilization method was boiling jars for 5 hours straight</p> <h3><span id="USDA_Canning_Publications_1917">USDA Canning Publications (1917)</span></h3> <h4><span id="Farmers_Bulletin_839_later_named_the_Home_Canning_by_the_One_Period_Cold_Pack_Method">Farmers’ Bulletin 839, later named the “Home Canning by the One Period Cold Pack Method”</span></h4> <p>This bulletin focussed on how to operate canning equipment properly. It dropped the fractional sterilization method.</p> <p>It worked with three heat sterilization methods: boiling water bath (100 C / 212 F), ‘water seal’ process (101 C / 214 F), and steam pressure processing at 5, 10 or 15 psi. For the jars, it recommended screw top containers.</p> <h4><span id="Farmers_Bulletin_853_named_Home_Canning_of_Fruits_and_Vegetables">Farmers’ Bulletin 853, named ‘Home Canning of Fruits and Vegetables’</span></h4> <p>This complementary bulletin was issued a few months after Farmers’ Bulletin 839.

Even in the commercial canning world, outbreaks of botulism from products were common. Knowledge of bacteria was still racing to catch up with the needs of the canning industry.</p> <p>Before 1919, the USDA was operating under the assumption that botulism spores were killed by exposure to 80 C (175 F) heat for one hour, based on what textbooks at the time were saying. In 1919, however, the researcher Georgia Spooner Burke in her lab experiments found that the spores were surviving being boiled for 3.5 hours, and in 1921, H. Weiss found that spores were surviving being boiled for up to 5 hours.</p> <p>In 1923, formulas were finally developed by Charles Ball which were reliable and became the basis for calculating thermal processing requirements for canning.</p> <p>Between 1930 and 1935, research studies were done on meats, particularly chicken and beef. Subsequent publications included these results.</p> <h3><span id="USDA_Canning_Publications_1936">USDA Canning Publications (1936)</span></h3> <h4><span id="Farmers_Bulletin_1762">Farmer’s Bulletin 1762</span></h4> <p>This bulletin covered canning fruits, vegetables and meats.

You should consider writing to your elected representatives to tell them that this is a question that is important to you and other home canners, and that you’d like them to toss a few shekels to the NCFHP so that they could undertake research on this (after all, the government is never *not* going to spend your money, it might as well go on something useful, and they keep the NCHFP on bare life support.)</p> <p>Anyway, I hope the Ball / celery information helps — at least you’ll know who to chase after!
