The Food Warden sticker, containing our modified Bacillus bacteria, could be perceived as a potential product. Therefore, we decided to conduct a market research survey, where we ask the respondents questions about their general food habits and if they would be interested in Food Warden as a possible product on the market. We also ask if they consider using a GMO-containing sticker next to food as safe. We used the surveygizmo survey engine for this task.

The respondents

We received a total of 167 responses to the survey. Most of our respondents (56.3%) were 16-25 years of age, 22.2% of the respondents were older than 40, and 21% of age between 26 and 40. Only one respondent (0.6%) was younger than 16 years of age.
This portrays our respondent group as young crowd, and in fact we recruited many of our respondents from students of our university (however, of multiple faculties - these are not biology students only!)
Vast majority (77.2%) of the respondents answered that they go grocery shopping on their own, and do they cook on their own.

Also, most of them (88.6%) buy their meat at the supermarket. The biggest group of the respondents buys meat two-three times a week (36.5%), or almost everyday (27.5%). Overall, more respondents buy food products in smaller amounts, only what they need immediately, even if it costs more (54.5%) compared to buying bigger ("family") packages to save money (45.5%).

Best before dates and food waste

The opinions of the respondents on "best before" dates are split: 52.1% does not think that such dates give an accurate measure of food edibility, while 47.9% believes they do. According to our survey results, many of the respondents throw away food - if they are not certain if it is good - relatively rarely (once a month - 46.1%, never or almost never - 21%). However, roughly a third of the respondents admits they do that often (29.3% - few times a month, 3.6% - more than once a week).

Food Warden as a potential product

85.2% of the respondents would like to use a product like the Food Warden sticker to indicate whether their meat is good to eat or not, out of which 72.5% would like to be sure if their meat is safe to eat, and 9% would be able to save money through buying bigger meat packages.

Interestingly, 67.7% of all respondents are willing to pay extra for their meat to include such a product, 5-15 eurocents or more.
Moreover, 82.5% of the respondents would like to see a product like Food Warden on the market; 12.1% like the concept, but wouldn't use the product; only 5.4% think such product is not needed.

GMOs next to food

Since we were asked by many people about public perception of using GMOs next to food, we asked our respondents very important question: Considering all of our safety measures, would you think the product containing GMOs would be safe to use next to your food? 55.8% answered yes, and 38.8% were not certain and would need to learn more about the safety measures. Only 3% of all respondents do not think it is safe.

Conclusions

We were positively surprised how enthusiastically many of our respondents reacted to our concept and the project. Among the feedback, we got some very thoughtful ideas about features that Food Warden would need to have as a product, but also many heart-warming messages (we keep the original spelling, mostly):

There is nothing more harmfull about the bacteria you used than one that might get on my food from whatever surceincluding myself, for as far as I know you are not using a bacteria that is pathological in any sense, and the proteins produced by the bacteria will not be harmfull either. There is no biohazard.

Save consume with FoodWarden! This is GOLD if you succeed and keep on trying to conquer the market. Just go for it!

I find it a very elegant system, because it prevends us from thoughing away good perfectly fine food.

It should be an European standard. You never know what producer, re-seller or retailer did with 'best before' dates. And most meat doesn't have it. On the other side 'best before' dates are not really a deadlines, so a lot of food is wasted, because it had reached its 'best before' date, but it is still eatable

I like the idea, and I think a lot of people will benefit from the product. Especially people who throw away food too soon with the only reason that it is at the expire date but still fine to eat

something like that should be standard

It is very usefull. I would like to see products associated with this idea.

Very good initative-hope it will be a hype on the market !

Even though most the respondents of our survey say they do not throw away food often, they would still be interested in our product. It is also very surprising to see that almost none of the respondents reject the product immediately because of GMOs, even though they would have to put it next to their food, in their fridge. We think that the perception of GMOs in the society is changing and is growing in acceptance, as long as it is closely watched and controlled. People realise that insulin for diabetic patients is produced by GMOs, and that many crops and vegetables are genetically engineered. Even among the oldest respondents (age 40+), 36.1% they would consider the product safe, and 52.8% chose the answer "maybe".

In general, our respondents were interested in the product as a food safety indicator, even if they do not throw away large amounts of food before due date, even if they do not suffer from food poisoning often. Interestingly, most people would like to pay a considerable amount of money extra to have a sticker like that included with their meat, and that underlines that there is a need for a product like Food Warden on the market.
