Lifting the Lid on Can Opener Hygiene with Bonzer!

Mitchell & Cooper are UK manufacturers of the iconic Bonzer® can opener.

Although the name Bonzer® is often applied generically to any tabletop can opener, authentic Bonzers® are distinguishable by the red knob on the handle.  They have been in production since the 1940’s but the design is being constantly updated to meet the demands of contemporary catering.

The latest features to be added are a dishwasher friendly blade and cutting mechanism and blades with an anti-bacterial coating, perfect for maintaining hygiene standards in a busy professional kitchen.

But what’s the message on hygiene we hear you ask?!

It’s a scene every head chef can identify with. The Environmental Health Officer is coming for an inspection and the whole team has been polishing the kitchen and cleaning under the ovens and behind the fridge. However, on arrival the EHO goes straight to the can opener. Did you know that this is the most popular first step of most EHO’s?

Now industry has finally reopened, it is important that we think about the inevitable visit from our friends in the white coats.

Kat Cooper, Project Director at Mitchell & Cooper said

“The Environmental Health Officers often head straight for the can opener because it’s one of the most common items that chefs don’t consider on a deep clean or for general maintenance.  Residue from multiple can openings gets left on the blades and cogs of the opener.  This not only affects its functionality, but also provides a breeding ground for germs and bacteria.”

Thankfully, this can now be avoided by using one of the new Bonzer Titan openers with removable blades like the heavy duty Bonzer Titan Super Bench Can Opener.

This uses a stainless-steel blade fitting and titanium coated blade that gives greater cutting power and durability. But the clever bit is a dishwasher-safe trigger mechanism and a quick-releasing, anti-bacterial blade.

Now, the opener can be cleaned properly and kept hygienic, so you won’t get caught out at your next EHO visit.

Here are some top tips from Bonzer HQ:


  • Open the tops of cans not the bottoms, store cans such as beans, upside down.
  • Open dented cans from just to the left of the dent.
  • Turn the handle clockwise - anticlockwise rotation could loosen the mechanism.
  • Never turn the handle continually without a can in place.
  • When replacing the can opener - change the base as well.
  • Never sharpen the blade - sharp blades cause sharp edges.
  • Replace chipped blades and wheel.


Richard Davies, Executive Chef at Calcot Hotel & Spa, Tetbury said 

“My Bonzer can opener has been here at Calcot ever since I can remember, it’s probably older than me – They last a lifetime and are an integral part of the kitchen, and as such, should be maintained to the same standards as all other equipment – We certainly couldn’t do without it.  There are other brands available, but none withstand the constant heavy usage that a Bonzer does – It really isn’t worth compromising on quality as you will finish up paying more in the long run, in terms of both down-time and money."
