What's the job really like?
Andrew Taylor - Environmental Health Officer
"Hey Michael, how're you doing?" asks environmental health officer Andrew Taylor as he strides into the restaurant he is about to inspect. Michael smiles, "I'm just about to have my breakfast. Want some?"
Politely declining the offer, Andrew follows Michael into the kitchen. He listens carefully as Michael describes how things are going with food safety procedures put in place last month. Andrew then suggests some improvements the restaurant can make, ensuring the manager understands exactly what is required.
As Andrew has been covering restaurants and cafes in a small area of Wellington city for several years, he's got to know his clients well. "It's crucial that you tap into this connection – this alone will make them want to tell you about the way they're doing their business.
"It's only then that you get a better idea about how they can make improvements from a food safety point of view. If I ask them to spend $10,000 to $15,000 to change their ventilation system, for example, they will be more likely to understand why.
"Through these inspections, I've met some fantastic people with amazing stories that I might not otherwise have met."
Amokura finds out what it's like to be a health protection officer - 6.49 mins. (Video courtesy of Ministry of Health).
Clinton: Helping to make New Zealand a safer place to be is health protection officer Cameron Ormsby.
Cameron: Kia ora Amokura, my name is Cameron and I’m going to be taking you around for the day.
Clinton: Part of a health protection officer's job includes monitoring and removing potentially dangerous exotic mosquitoes from around New Zealand’s ports and today Cameron has taken Amorkura to Ports of Auckland.
Cameron: OK Amokura, this looks like a good spot. We’re looking for somewhere dark, where lots of mozzies can hide and rest. So this looks like a perfect spot so what we’re going to do now is we’re going to set up our adult trap and we’re going to try and catch some mosquitoes, so here we go.
Cameron: What I like about my job is that it’s a great mixture of being out in the field and also back in the office. So it’s that real application of science in a work sense. You finish the day and you look at what you’ve done and you’ve achieved your goal of protecting the health of a large number of people.
Cameron: Basically, red to positive, black to negative.
Cameron: This mosquito trap has a jar of liquid with a little wick on the end, and it’s what we call Octanol – it’s chemical formulation, and it’s the same as what we call bad cow's breath, so basically the mosquitoes smell bad cow's breath, get really interested, and they come up to here and they get sucked down by the fan and into the trap.
Clinton: A trap set up earlier has captured some suspect mosquitoes.
Cameron: Oh yeah there’s a couple, excellent. We have to chuck them in our vial for sending to the lab.
Clinton: But before they head back to the lab it’s off to carry out some inspections on a farm. Here they must ensure that all pest control chemicals such as the deadly cyanide are stored away safely, out of harm's way.
Stu: What we’ve got in here is actually quite dangerous. There’s a lot of toxins that can be stored in here at any one time, so it’s really good to get some feedback on actually how to look after it.
Cameron: The first thing we’re going to look at with Stu is how he is storing his goods, and how he has the appropriate storage for his goods. So you can clearly see that Stu has got his poisons stored here, and he’s got clear signage saying it’s a toxic substance, it’s a Class 6, and that’s brilliant, and he’s got it on some other areas where he’s storing his cyanide, so Stu, that’s brilliant.
Clinton: Having ensured there is clear signage to alert the public, Cameron checks that all poisons are safely locked away, there is good ventilation in the container and the correct paperwork is displayed. Out in the field they check that the bait station is also set up correctly.
Cameron: So we’re looking primarily at how he’s put the bait in a secluded spot, and the public health risk is severely mitigated.
Clinton: With no risk to the public it's time to head out and ensure future baiting plans are safe for both native species and people.
Farmer: I’d like to permanently bait this area of bush down below us here. It’s got a good set of conservation values – it’s got frogs and kauri snails.
Cameron: The people skills that you really need as a health protection officer are being able to problem-solve, that’s a key one, but also being able to relate to other people because often you’re having to work with other groups or organisations to solve a common problem and it’s using your skills of persuasion and people skills to really drive home the message of public health and get action.
Clinton: Health protection officers also investigate environmental hazards that may contaminate food sources. Heading out to an oyster farm Amo and Cameron are looking to spot any pollution sources running from the land into the oyster growing area.
Cameron: Out here we’re looking at a number of properties which border the river and also a lot of farmland so we’re looking at areas where there may be things like failing septic tanks where I guess pollution might come into the river, so that’s what we’re checking today. Amo, a good tool in public health is being able to map where pollution sources are. So if I give you this GPS tracker and you input the co-ordinates of these pollution sources so that we can look at them on a map, that would be great.
Clinton: Farm animals are a potential source of pollution to nearby waterways and Amo enters the GPS co-ordinates ensuring they can pinpoint the exact location on a map.
Cameron: It’s not legal to discharge pollution directly into a water body like this. So what we’re really trying to do as public health staff is we’re really trying to knuckle down on pollution source before they become a problem, and it’s great for New Zealand industry, and it’s great for the farmer in particular.
Cameron: We’ll take these back to the lab and we’ll see what the results are like.
Clinton: A big part of the job takes place back at the office, analysing results from out in the field.
Cameron: What we’re going to do Amo is we’re just going to look at these shellfish results. One thing that’s really exciting about a health protection job is you come into work and you’re not 100% sure what you’re going to end up doing that day. Things change from time to time. For example, you come in on a Monday and you’re running off to a big swine flu event, and the next day there will be a radiation event where someone will crash a truck carrying a radioactive substance, so no day is going to be the same.
Cameron: The waters are really good and the oysters are really good to eat so it should be a good harvest.
Clinton: With the oysters given the all clear for public consumption, Amo and Cameron take a closer look at the day's earlier catch.
Amokura: So how do you know if it is a dangerous mosquito?
Cameron: Well different aspects of mosquitoes are unique to each individual mosquito, so we’re looking at things like black or white stripes on the legs, or on the proboscis, and also I guess how its abdomen is shaped and how its wings are shaped, and what you’ll see there is a bit of black and white striping on it. It tells me initially it is a species native to New Zealand, but we’ll still send it to the lab for a proper ID.
Clinton: So how did our student go?
Cameron: I thought he went really well, he’s got a real appreciation of public health and the broader concepts of health. He’s also got that real scientist eye – I saw a gleam as he was looking down the microscope so I’ve got big hopes for him.
Amokura: I really enjoyed the job and I didn’t even know anything about health protection officers and I really enjoyed going out on the oyster barges.
