September is National Food Safety Education Month and my contribution to nutrient safety education is solid food rubber and canning . So this month is going to be a free training each workweek on canning for beginners and solid food safety .

Bad Bugs
Let ’s talk a piddling piece about Clostridium botulinum , which is the shuddery of microbes when it come to canning . These causal agency botulism and is why pressure canning is the only advocate method for put up low window pane intellectual nourishment like meat , Pisces the Fishes , seafood , poultry , and veg . This is why you should never , ever apply a piss bath canner for humbled window pane food .
These suckers organise a spore which is kind of like a medieval suit of armour . It protects the bacterium cell so it can survive and grow inside a sealed jounce of intellectual nourishment and produce a toxin that is toxicant . It is this toxin that can be black . Even just a taste . They are destroyed by using a pressure canner at the proper pressure sensation for your ALT and the right processing meter .
Now before you grab a paper bag and run to the corner to start hyperventilating and throw out everything you canned , I require you to know that boiling food that was canned for 10 minutes plus 1 minute for every 1000 ft above ocean level should destroy the toxin . So if you are at 5000 ft boiling point for 15 mo . That ’s 10 minute plus 5 for the additional 5 x 1000 ft .
Boil low dose and tomato - ground food like this , even if they do not show signs of spoiling . This does n’t entail to say you may ignore proper canning practices and processing times and your practiced defence is to follow proper canning practice and food condom to help keep you and your get laid ones secure .
For low acid foods check that :
If in doubt, throw it out!
Properly canned foods should :
Food Poisoning
Foodborne illness or food poisoning to you and me is get by disease - causing bacterium known as pathogens that pollute food . nutrient toxic condition case are about 48 million a year , that ’s 1 in 6 Americans each twelvemonth . Some people are more at peril than others like kids under 5 , adults over 65 , if you ’re fraught and people with wellness trouble that are immunocompromised .
pollute food will usually cause you to be sick within 1 to 3 days of rust that food but sometimes you getting sick can happen within 20 instant or in some people up to 6 weeks later ! Most of us have had food toxic condition at some point in our aliveness , the improperly cook bacon butty , the dodgy drunken takeaway , a petrol place chicken sandwich maybe , or how about getting disgusted on that 18 - hour flight of steps after grabbing the last egg salad in the aerodrome ?
Most of us as adults can recall those symptoms of foodborne illness like vomiting , looseness of the bowels , abdomen or abdominal pain in the neck , or flu - same symptom like fever , head , and torso ache and none of us retrieve food poisoning with happy memories !
At home , there are other contribute factors that can stimulate us to accidentally induce food toxic condition in ourselves and others . Contributing constituent are deportment , practice session , and even environmental conditions that take to incidences of food for thought poisoning . experience them means we can contain them . There are 3 types of bestow component .
The good word is that we can keep ourselves and our bonk ones safer from nutrient toxic condition with these stone’s throw !
Food Safety Steps
wash away your paw and surfaces often when working in the kitchen prepping and canning .
paw washing is extremely important but most hoi polloi do n’t wash their hands long enough ! At least 20 seconds of lather and scrubbing with Georgia home boy and warm piddle helps to take away the bacteria . you’re able to babble out Twinkle Twinkle Little Star or ABC or do 2 rounds of Happy Birthday in 20 seconds and your manus will have far few bacteria on them than if you were to just glance through running water as quickly as possible .
Wash your hands after doing things in the garden , harvesting , weeding , deal compost , and making innate fertiliser . rinse your hands before and after handling intellectual nourishment , and of trend , after using the bathroom and handling darling .
Clean your harvested or purchase fruit and vegetables under tap water including those with skins or rind that are not eaten like squash vine , avocado , melon vine , scrub bring out with a clean produce brush to help remove bad bacteria . Wash leafy greens and fresh herbs with dozens of clean running tap piddle .
clean your garden truck is important because they grow in and on the ground and the soil has mint of microorganisms in it . Not all of them are regretful . But some are and we do n’t require to enter those into the shock and terminate foods we are pass to make at home plate . The same matter for clean utensil like knives , spoons , canning jars , and cutting board . Wash with live soapy weewee after train each food item and top food guard bakshis used by chef is to use one hack display panel for overbold green groceries and a separate one for naked gist , poultry , and seafood .
Clean your canning jounce in hot soapy water and rinsing thoroughly then , place them upright into a water bathing tub canner on a wheel and cross them with warm piddle . Bring them to the boiling point and boil for 10 transactions . If you ’re at altitude of more than 1000 ft above ocean level , add an additional minute for every 1000 ft . So if you live at 7000 ft you would total 7 min so your sterilisation clock time is 17 transactions . Keep jars in hot water until you are ready to occupy them .
Why so long at altitudes?
Well , water boils at lower temperatures as the altitude increment . scurvy stewing temperature are less good at kill bacteria so increasing the boiling time ( and also the processing clock time in the canner or the pressure if insistency canning ) compensates for the low stewing temperature to right kill the bacterium .
How canning preserves your food
novel food spoilage very easily because they incorporate a lot of water . They are great places for microorganism like bacteria , yeasts , and mould to grow . novel food can go bad not only from these microorganisms but also from enzymes in the food , atomic number 8 in the melody , and lose water .
Microorganisms live , grow , and multiply faster than rabbits ! They are on solid food surfaces of refreshed produce and inside bruised , worm - damage and diseased nutrient . In the correct condition like temperature and useable solid food and water stage , bacteria multiply every 20 instant so 1 bacteria cellphone will become 2 in 20 minutes , those 2 in 40 minute become 4 after 10 hours you ’re take care at over 1 billion bacteria cadre ! Yikes !
So some right canning practices are to :
all in all , these helper to remove atomic number 8 from the nutrient , destroy and denature enzymes , prevent the maturation of microorganisms ( those unwanted yeast , molds , and bacteria ) and facilitate to form a good vacuum cleaner in the jounce . A good void means a tight seal that keeps the food inside and microorganisms and gentle wind out of the jar to protect the food you carefully grow and keep up to savour later in the season .
