Food truck operators need tools to reduce risks – like a handwashing sink

I like a good food truck meal. The experience is less about eating food from a small sweaty kitchen and sitting on the ground and more about ordering something from a small menu that the chef specializes in. A couple of weeks ago I had a fantastic sautéed cauliflower and roasted potato pita from a food truck at a community event.foodtruck

Before eating there I checked out whether they had an inspection grade (because there are some trucks that like to operate incognito, outside the law) and asked how they washed their hands. The chef told me that they have a handwashing sink with running water and a collection tank. I still have to trust that he actually uses it but at least he had the tools.

That’s a bit different from a food truck on the Carnegie Mellon campus. According to the Pittsburgh Post-Gazette, Tartan Express was forced to close following an inspection where they were cited lots of risky things including not having a sink.

The Allegheny County Health Department has cleared the Tartan Express food truck on the Carnegie Mellon University campus to reopen after it was closed earlier this week for multiple food safety violations, including lack of running water.

The truck, which serves Asian food, operates at 5000 Forbes Ave. “No one in the vehicle is able to wash hands when beginning new tasks, after handling money or touching the face or hair,” an inspector wrote this week.

Other violations included holding food at unsafe temperatures and inadequate sanitization.

Handwashing in the field: soap or sanitizer or both

Effective hand hygiene is essential to prevent the spread of pathogens on produce farms and reduce foodborne illness.

dirty.handsThe U.S. Food and Drug Administration Food Safety Modernization Act Proposed Rule for Produce Safety recommends the use of soap and running water for hand hygiene of produce handlers. The use of alcohol-based hand sanitizer (ABHS) may be an effective alternative hygiene intervention where access to water is limited. There are no published data on the efficacy of either soap or ABHS-based interventions to reduce microbial contamination in agricultural settings.

The goal of this study was to assess the ability of two soap-based (traditional or pumice) and two ABHS-based (label-use or two-step) hygiene interventions to reduce microbes (coliforms, Escherichia coli, and Enterococcus spp.) and soil (absorbance of hand rinsate at 600 nm [A 600]) on farmworker hands after harvesting produce, compared with the results for a no-hand-hygiene control.

With no hand hygiene, farmworker hands were soiled (median A 600, 0.48) and had high concentrations of coliforms (geometric mean, 3.4 log CFU per hand) and Enterococcus spp. (geometric mean, 5.3 log CFU per hand) after 1 to 2 h of harvesting tomatoes. Differences in microbial loads in comparison to the loads in the control group varied by indicator organism and hygiene intervention (0 to 2.3 log CFU per hand). All interventions yielded lower concentrations of Enterococcus spp. and E. coli (P < 0.05), but not of coliforms, than were found in the control group. The two-step ABHS intervention led to significantly lower concentrations of coliforms and Enterococcus spp. than the pumice soap and label-use ABHS interventions (P < 0.05) and was the only intervention to yield significantly fewer samples with E. coli than were found in the control group (P < 0.05). All interventions removed soil from hands (P < 0.05), soap-based interventions more so than ABHS-based interventions (P < 0.05).

ABHS-based interventions were equally as effective as hand washing with soap at reducing indicator organisms on farmworker hands. Based on these results, ABHS is an efficacious hand hygiene solution for produce handlers, even on soiled hands.

Handwashing with Dr. Oz (‘never heard of him’)

I was talking to a medical doctor and a couple of his students, and a New York City trip is in the works, and I said I’d only been to NYC a couple of times, including when I was on Dr. Oz.

Dr. Oz“Who’s Dr. Oz?”

“A television celebrity medical doctor.”

“Why would he call himself Dr. Oz? Does he represent all of Australia?”

Communication breakdown.

One of the students explained who Dr. Mehmet Oz was and how he was spawned from Oprah.

“Never heard of him.”

Dr. Oz released a handwashing video and it’s not bad. They got the water temperature bit right (so please, everyone else stop saying it has to be warm water, that’s just a personal preference).

They also got the soap and friction bit right.

The 20-second bit? Not so right.

So I turned to handwasher-in-chief, Don Schaffner of Rutgers University, who offered the following comments:

“The U.S. Food and Drug Administration model food code says two things: In section 2-301.12 it says “warm” water must be used for handwashing.  It’s isn’t science based as far as I know.

“In section 5-202.12 it says the handwash sink must provide water at a temperature of at least 38 °C (100 °F).  Also not science based.

“The video mentions 20 seconds.  As far as I know, that’s not science based either, and while it’s a perfectly fine length of time, 30 seconds would be better, and 15 seconds would be almost as good.”

Life of Poo handwashing: 30-second food safety stories

Everyone says they wash their hands.

life-of-pi_0But when researchers look, most don’t

(especially men).

A UK professor wrote a book, The Life of Poo,

Sorta like the Life of Pi (and the last book I read).

He says toothbrushes should be 2m from the loo.

And he says, no one washes their hands in a way that will work.

“Whether you are brushing your teeth, having sex, cleaning your bathroom, following the 2-second rule, debating the 5-second rule, guzzling probiotics or just sitting on the toilet, this book is likely to be of interest to you.”

 

30-second food safety stories.

I wash my hands.

I’m no Yogi Berra, but this Taco Bell worker caught with hands down his pants

There’s an old food safety saying: gloves give a false sense of security, and it doesn’t matter whether wearing gloves or not, you scratch your ass, bacteria are going to move.

taco.bell.2OK, it’s my saying.

Been making people cringe for 20 years.

But now, because everyone has a camera, there’s photographic proof.

A customer at an Ohio Taco Bell noticed one of the employees behind the counter had his skillful taco-making hands inside his pants, brushing up against his backside.

The customer posted the picture to Taco Bell through Facebook, and according to Fox 8, the employee was identified, then fired.

Taco Bell said:

“This is completely unacceptable and has no place in our restaurants. Our franchisee took immediate action, and has terminated the employee and retraining the entire staff. We want customers to know that the person in the photo was never in contact with the food, and that the Health Department inspected the restaurant and approved its operations.”

They couldn’t fire the guy fast enough, though, as the memes quickly started pouring into Taco Bell’s site.

If someone tried ordering a Choco Taco, this guy was definitely delivering.

But instead of the corporate apologetics, Taco Bell could have found a more fitting use for its PR thingies.

RIP Yogi. King of the soundbite

yogi.bera.sep.115Before athletes were required to have a Facebook, Twitter and Instagram in addition to their busy schedule of pre-, post- and mid-game interviews, Berra’s prowess with a funny quip and quick soundbite rivaled his skill on the field.

Lines like “It’s déjà all over again” have bcome so ubiquitous that they simply seem to have sprung, fully formed, from the American vernacular.

1, When you come to a fork in the road, take it.

  1. Ninety percent of the game is half mental.
  2. You wouldn’t have won if we’d beaten you.
  3. Make a game plan and stick to it. Unless it’s not working.
  4. We made too many wrong mistakes.
  5. Why buy good luggage, you only use it when you travel.
  6. All pitchers are liars or crybabies.
  7. Even Napoleon had his Watergate.
  8. If the world were perfect, it wouldn’t be.
  9. Take it with a grin of salt.

Entire publications have said less with many more words.

142 sickened with E. coli from UK takeaway because staff fail to wash hands

More than 100 takeaway customers were sick for up to two months with a rare strain of E. coli – after staff did not wash their hands after using the toilet, a court heard.

handwashing.sep.12Nottingham Crown Court heard that 142 customers of the Khyber Pass in Hyson Green, Nottingham, suffered with nausea, vomiting and diarrhea after the outbreak last June.

In one case, a 13-year-old girl spent four nights in hospital with a consultant saying the infection could have been fatal if it was not treated.

Amjad Bhatti and Mohammed Basit, owners of the Khyber Pass, in Gregory Boulevard, pleaded guilty to seven food hygiene offences and were sentenced on Wednesday.

Prosecuting, Bernard Thorogood said that nine of the 12 members of staff who handle food at the takeaway were found to have traces of the bacteria, and one of the defendant’s daughters fell ill.

Mitigating, Robert Egbuna said lessons had been learnt and improvements made at the takeaway.

He said: “It is not just a case of adding hand basins. There have been significant changes that have come about from the real shock of what has happened.”

Bhatti and Basit were both given four months prison suspended for a year, as well as being ordered to do 250 hours of unpaid work each.

His Honour Judge Jeremy Lea also said each of the victims should be paid £200 compensation by the defendants as well as paying costs of £25,752.36.

Not so: Antibacterial handwash ‘no better than soap at killing germs’

Food micro geek Don Schaffner of Rutgers University responds in a point-counterpoint style discussion of antibacterials in soap and effectiveness.

point.counterpointAccording to the story, a new study published in the Journal of Antimicrobial Chemotherapy found that antibacterial handwash is no more effective than plain soap at killing bacteria.

In recent years numerous products have appeared on the shelves claiming they were effective in killing 99.9 per cent of all germs.

But Korea University scientists investigated the effect of triclosan, the most commonly used active antiseptic ingredient in soap, in everyday conditions on bacteria such as MRSA, salmonella and listeria.

In recent years numerous products have appeared on the shelves claiming they were effective in killing 99.9 per cent of all germs. That’s actually a regulated label claim.  And it’s not “99.9 per cent of all germs.”  It’s 99.9 percent (3 log reduction for the math nerds) of certain regulatory-specified organisms under specified test conditions.

One central key weakness of the study is that authors state in their methods, “Antibacterial soap had the same formulation as plain soap except that it contained 0.3% triclosan.” While this might seem to be a good idea from the science perspective, it turns out that soap formulation is a tricky business. For antimicrobials to be optimally effective, the formulation might need to be adjusted. You can’t just throw sh*t in at ‘the maximum allowed by law’ and expect it to work.

Handwashing intervention in daycares doesn’t reduce illness

Either the employees were already real good at hand hygiene, or the interventions didn’t resonate with people.

dirty.jobs.daycare.e.coliInfections are common in children attending daycare centres (DCCs). We evaluated the effect of a hand hygiene (HH) intervention for caregivers on the incidence of gastrointestinal and respiratory infections in children. The intervention was evaluated in a two-arm cluster randomized controlled trial.

Thirty-six DCCs received the intervention including HH products, training sessions, and posters/stickers. Thirty-five control DCCs continued usual practice. Incidence of episodes of diarrhea and the common cold in children was monitored by parents during 6 months. Using multilevel Poisson regression, incidence rate ratios (IRRs) with 95% confidence intervals (CIs) were obtained. Diarrheal incidence was monitored in 545 children for 91 937 days. During follow-up, the incidence was 3·0 episodes per child-year in intervention DCCs vs. 3·4 in control DCCs (IRR 0·90, 95% CI 0·73–1·11). Incidence of the common cold was monitored in 541 children for 91 373 days. During follow-up, the incidence was 8·2 episodes per child-year in intervention DCCs vs. 7·4 in control DCCs (IRR 1·07, 95% CI 0·97–1·19).

In this study, no evidence for an effect of the intervention was demonstrated on the incidence of episodes of diarrhea and the common cold.

Blame consumers: How to handle an egg edition

Less than half of adults, only 48 percent, wash their hands with soap and water after cracking eggs, and over 25 percent eat cookie dough or cake batter containing raw eggs, according to a study published last month in the Journal of Food Protection. Both activities put a person at serious risk for food poisoning.

raw.egg.mayo“It’s shocking,” says lead author Katherine Kosa, a research analyst in food and nutrition policy at RTI International, a nonprofit research organization based in North Carolina. In an earlier study, her team found that 98 percent of people wash their hands after handling raw poultry, but somehow that same logic hasn’t extended to eggs, she says.

She and collaborators surveyed 1,504 US grocery shoppers about their food-handling habits. The researchers were happy to find that 99 percent of people purchased refrigerated eggs and kept them refrigerated. Keeping eggs adequately cool prevents any salmonella present in the eggs from growing to dangerous levels.

Atlanta café sucks at handwashing

Multiple food prep employees at Saigon Cafe in Buford were only rinsing their hands briefly in cold water while prepping food during a recent inspection, leading to a failing health score.

buford.t.justiceThe Gwinnett County health inspector said another employee touched raw beef with gloved hands, then took off the gloves to handle ready-to-eat foods but didn’t wash his hands to ensure they were free of contaminants.

The inspector said there was no managerial control over food safety at the restaurant. Saigon Cafe, 3380 Buford Drive, scored 44/U on the routine inspection. Previous scores were 85/B and 80/B.

Points were also taken off because improper cooling methods were being used for potentially hazardous foods. Cooked chicken, pork and chicken broth were all discarded because they had not cooled sufficiently in the time allowed.

Several items in coolers were not separated to prevent contamination. Unwashed fruits and vegetables were not separated from the ready-to-eat foods, and loosely wrapped packages of raw pork spring rolls and vegetable spring rolls were stacked together.
