Food safety , sous vide
Food safety is always a paramount concern in cooking. Of course, sous vide is no exception. The sous vide process has some benefits and some quirks in this regard. The Cinder Grill, with its modified Sous Vide process, has some of the same features and some unique features, as we’ll explore in this essay.
Food Safety: a Quick Overview
‘Food Safety’ as a concept is the prevention of foodborne illness and injury by correctly handling, preparing, and storing food. That sounds a little scary, but it’s actually not that difficult. Also it’s absolutely necessary, as anyone who’s suffered food poisoning can testify. With the sous vide method of cooking the focus is on handling and preparation of food, although storage also comes up. Because of the relatively low temperatures used in sous vide, one major consideration is the Danger Zone.
How to Avoid the Danger Zone
The ‘Danger Zone’ is a range of temperatures where bacteria particularly thrive and multiply. It’s generally defined as 40F to 140 F, or 4.4C to 60C . Many foods are best cooked to temperatures within this range, especially those with varied donenesses such as meat and fish,. However, the time they spend in this range needs to be minimized for optimal food safety. Sear them, serve them or chill them immediately upon reaching doneness.
This is one area where the Cinder Grill improves on traditional sous vide. Because it can bring a steak to temperature in one hour rather than six, the food spends far less time in the Danger Zone and is much less prone to spoilage.
How to Sous Vide Safely
With these considerations in mind, here are some tips on how to sous vide safely. All of these apply to cooking with the Cinder Grill.
- Obtain an accurate digital “instant-read” thermometer. This is for checking the temperature of both raw and cooked food to ensure that it reached a desired end point.
- Use separate surfaces for raw and cooked food, such as a new plate when removing cooked food from the Cinder Grill. This prevents bacteria from raw food from contaminating the cooked food.
- Consider food thickness. Thicker food reaches its final temperature more slowly, which means it must spend longer in the Danger Zone. Consider cutting a thick piece into two thinner pieces.
- Make certain that there are no air pockets in the sous vide bag, which will inhibit heating and can result in undercooked and thus dangerous regions. This is another place where the Cinder Grill is at an advantage; because it doesn’t need bags, there can be no insulating air pockets.
- Once the food is cooked, promptly sear and serve, serve, or refrigerate.
Storage and Serving
As we mention above, if the food will not be eaten immediately it should be chilled immediately to remove it from the Danger Zone. One of the convenient aspects of sous vide is that it reheats efficiently, so there’s no reason to “hold” the food at a warmer temperature. The Cinder Grill does even better at this: it has a built-in “hold” mechanism which keeps the food safely at temperature until you are ready to serve. It also reheats food excellently, even faster than water-based sous vide.
Some Final Notes on Food Safety.
Food safety is of course essential, but it doesn’t need to be difficult. Simply store food at appropriate cold temperatures when it’s not being cooked or served, and maintain proper hygiene. The Cinder Grill helps maintain food safety with its fast sous vide method and also its easy cleanup. Cook safely and deliciously with the Cinder Grill!

FAQs
Sous Vide Equipment
What hazards can you get from sous vide? ›
These risks include the potential for survival and growth of bacteria that can grow under the anaerobic (absence of oxygen) conditions created by the vacuum packaging, e.g. Clostridium botulinum. Remember, some foods may not be suitable for sous vide cooking.
What are the guidelines for sous vide food safety? ›
To make sure vegetative forms of pathogenic bacteria will be destroyed, always sous vide food at a temperature of 132.8℉ (56℃) or higher. Double check your circulator. To ensure your circulator's temperature is accurate, verify your water bath with a thermometer before cooking.
What are the FDA guidelines for sous vide? ›
Cook-Chill & Sous Vide Without a Variance
– Cooled to 34°F within 48 hrs. of reaching 41°F = 30- day shelf life; – Cooled to 34°F within 48 hours of reaching 41°F, removed from 34ᵒF, and maintained at 41°F ≤ 7 days (can't exceed 30 days);
Do you need a Haccp plan for sous vide? ›
Sous vide is a ROP process. With the exceptions identified below, sous vide processing requires a HACCP plan and may also require a variance. 2. ROP is NOT defined as packaging food items in a zipper/press and seal storage bag.
What is the danger zone for sous vide food? ›
Because of the relatively low temperatures used in sous vide, one major consideration is the Danger Zone. The 'Danger Zone' is a range of temperatures where bacteria particularly thrive and multiply. It's generally defined as 40F to 140 F, or 4.4C to 60C .
What is the warning about sous vide? ›
Do not sous vide for extended time below 130°F. This is called “incubation”, not “cooking”. Later, higher temperature cooking of these foods may not make the food safe. All perishable foods should be refrigerated at or below 41°F (5°C).
What is a major food safety concern for cook chill and sous vide packaged food? ›
Sous vide and cook-chill packaging may also be referred to as reduced oxygen packaging (ROP). Because the food is packaged in a reduced oxygen atmosphere, the main concern is the growth of, and toxin formation by, Clostridium botulinum and the growth of Listeria monocytogenes.
What are the bacteria of concern for sous vide? ›
Sous-Vide Processing
| Microorganism | Food |
|---|
| Staphylococcus aureus, Bacillus cereus, Clostridium perfringens, and Listeria monocytogenes | Salmon |
| Bacillus cereus spores | Chicken |
| Aerobic and anaerobic bacteria | Seasoned beef |
| Lactic acid bacterias, Bacillus cereus, Pseudomonas | Milk |
The plastic that touches the food is made of 100% polyethylene, contains no plasticizers or estrogen-like compounds. The FoodSaver bags are 5 layers of polyethylene with an outer layer of nylon. While you might get BPA from your cans of coconut milk, there is simply no BPA that will get into your food from sous vide.
Although some types of plastic have been found to release undesirable chemicals into food, especially under high heat or acidic conditions, the bags that we use for sous vide cooking are not among those plastics. High-density polyethylene, low-density polyethylene, and polypropylene are considered the safest plastics.
Do real chefs use sous vide? ›
For those who don't know, sous vide is a cooking method where food is vacuum sealed and cooked in a water bath under low temperatures, making it extremely tender and perfectly evenly cooked. Heston Blumenthal, the celebrity chef and master of molecular gastronomy, is one of the many big-name sous-vide fans.
When cooking sous vide What are the food safety challenges chefs face? ›
Food safety hazards are generally categorized as physical, chemical and microbiological. In sous vide foods, the hazard category of most concern is microbiological.
What is the health code for sous vide? ›
Section 114057.1 - Reduced-oxygen packaging method; HACCP plan; cook-chill or sous vide process, Cal. Health & Saf. Code § 114057.1 | Casetext Search + Citator.
Is sous vide a safe cooking method Why or why not? ›
Harmful bacteria can't grow above that temperature, and at around 135ºF, most bacteria will actually be destroyed after a few hours, making pasteurization possible. The precision temperature control of sous-vide cooking means it actually has the potential to be safer than traditional cooking methods.
Do I need a food sealer for sous vide? ›
No, vacuum sealing is not necessary for sous vide. In fact — and this isverycounterintuitive — foods inside a sealed vacuum bag aren'tunder vacuumat all!
What categories of bacteria can be a hazard in sous vide cooking? ›
This has led to concerns that psychrotrophic pathogens, such as Listeria monocytogenes, Yersinia enterocolitica, Clostridium botulinum, and the like could survive. The most hazardous of these is Clostridium botulinum, some strains of which produce a toxin at temperatures as low as 3.3 °C.
What is a disadvantage of sous vide? ›
Drawbacks of Sous Vide Cooking
Additionally, sous vide cooking can take longer than traditional cooking methods, since the food must be cooked for a longer period of time at a lower temperature.
