Didn't pressure can tuna long enough
Comments (4)jamhar, I was gone all day and just saw your post, did you make the 24-hour window for reprocessing? New lids, start just as though beginning for the first time, the timing must be consecutive uninterrupted minutes to be safe. 100 minutes. That was a shame, good news is while I prefer my tuna raw packed, I know many who pre-bake and that's the way the canneries do it too, they prebake whole fish then section off the meat and pack, can. My MIL didn't pressure can but she took whole tuna when she had it to the cannery, baked it there, filled the cans (and they really were cans not jars) and they canned it for her. The end product is more dry but can certainly be flaked up for tuna filling for sandwiches, used in casseroles etc. and may still be better than what you can buy at the store....See Morecanning tuna fish
Comments (9)Per NCHFP using quarts is not recommended. See link below for details. And the BBB says "Only can in half-pints or pints." I also checked several other canning sites with recipes for doing tuna and they all say the same thing - half-pints or pints only. I assume but don't know for sure, that it has to do with the density of tuna. Packed in a quart jar it would be difficult if not impossible to insure safe internal temps without an extraordinarily long processing time as it is already 100 mins. for pints. Simply adding more time won't insure the necessary temps are attained. Plus I would wonder, assuming you wouldn't use an entire quart at one time - that's a LOT of tuna salad ;) - once opened, how long would the remainder keep in the fridge without spoiling? I recommend freezing until you can get more pint/half-pint jars. Dave Here is a link that might be useful: NCHFP- Canning Tuna...See Morecanning tuna
Comments (2)I assume you mean filled up rather than the 2 or 3 inches your canner specified. NO it will make no difference in the tuna. The high pressure (and higher temp.) would have been throughout the canner. If you overfill canner, water instead of steam may blow out valve if you have that type. Jim...See MoreCanned tuna :-(
Comments (40)No one should be eating ANY tuna to excess: Excerpted from the EPA website (URL: http://water.epa.gov/scitech/swguidance/fishshellfish/outreach/advice_index.cfm): "By following these three recommendations for selecting and eating fish or shellfish, women and young children will receive the benefits of eating fish and shellfish and be confident that they have reduced their exposure to the harmful effects of mercury. 1.Do not eat Shark, Swordfish, King Mackerel, or Tilefish because they contain high levels of mercury. 2.Eat up to 12 ounces (2 average meals) a week of a variety of fish and shellfish that are lower in mercury. ◦Five of the most commonly eaten fish that are low in mercury are shrimp, canned light tuna, salmon, pollock, and catfish. ◦Another commonly eaten fish, albacore ("white") tuna has more mercury than canned light tuna. So, when choosing your two meals of fish and shellfish, you may eat up to 6 ounces (one average meal) of albacore tuna per week. ....6. The advice about canned tuna is in the advisory, but what's the advice about tuna steaks? Because tuna steak generally contains higher levels of mercury than canned light tuna, when choosing your two meals of fish and shellfish, you may eat up to 6 ounces (one average meal) of tuna steak per week. 7. What if I eat more than the recommended amount of fish and shellfish in a week? One week's consumption of fish does not change the level of methylmercury in the body much at all. If you eat a lot of fish one week, you can cut back for the next week or two. Just make sure you average the recommended amount per week." From Consumer Rpts (URL: http://www.consumerreports.org/cro/magazine-archive/2011/january/food/mercury-in-tuna/overview/index.htm) "Results from our tuna tests (canned, all kinds), conducted at an outside lab, underscore the longheld concern for those people. We found: Every sample contained measurable levels of mercury, ranging from 0.018 to 0.774 parts per million. The Food and Drug Administration can take legal action to pull products containing 1 ppm or more from the market. (It never has, according to an FDA spokesman.) The EPA compiles fish advisories when state and local governments have found high contaminant levels in certain locally caught fish. Samples of white tuna had 0.217 to 0.774 ppm of mercury and averaged 0.427 ppm. By eating 2.5 ounces of any of the tested samples, a woman of childbearing age would exceed the daily mercury intake that the EPA considers safe. Samples of light tuna had 0.018 to 0.176 ppm and averaged 0.071 ppm. At that average, a woman of childbearing age eating 2.5 ounces would get less than the EPA's limit, but for about half the tested samples, eating 5 ounces would exceed the limit. In 2006 we scrutinized the results of the FDA's tests in 2002 to 2004 of mercury levels in hundreds of samples of canned tuna. The agency's white-tuna samples averaged 0.353 ppm; light tuna, 0.118 ppm. But we found that as much as 6 percent of the FDA's light-tuna samples had at least as much mercury as the average in white tuna - in some cases more than twice as much. Given the uncertainties about the impact of occasional fetal exposure to such high levels, we urged the FDA to warn consumers about occasional spikes in mercury levels in canned light tuna. More than four years later, the FDA still hasn't issued such a warning. When we asked why, an FDA spokesman indicated that the agency had already taken the spikes into account when formulating its mercury advice. " ******************* ******************* BTW, if you think these guidelines ONLY apply to children or pregnant/nursing women, that's not true. A few years ago there was a report of an NFL football player who was trying to move to a healthier diet of less meat and lower cholesterol. As he didn't really like fish as a rule, he switched to canned tunafish. He was eating a can of tuna almost every day. After a few months he started to have numbness in his limbs (parethesia) and muscle weakness. A doctor finally diagnosed his illness, and got him on a natural detox diet. Extreme? Yes. But mercury poisoning is just as real a threat as lead poisoning. Heavy metals toxicity is something to always be aware of....See Morehomepro01
